Canonical Definition

The Software Security Standard (SSS) governs the establishment,

assessment, verification, determination, acceptance, and lifecycle
continuity of software security conditions.

SSS establishes the methodological conditions under which the security of a

software artifact, component, application, service, or integrated
system can be recognized as an identifiable, evidence-supported,
context-dependent governance state rather than an assumption derived
from implemented controls, successful security scans, the absence of
reported vulnerabilities, or declared compliance.

It governs the relationships among software security requirements,

protected assets, threat conditions, trust boundaries, attack
surfaces, security exposure, protective controls, security testing,
vulnerability identification, remediation verification, residual
security risk, and security conformity and acceptance.

SSS distinguishes declared security from demonstrated security, identified

threats from actual exposure, implemented controls from verified
effectiveness, vulnerability closure from verified remediation, and
security conformity from authorized acceptance of residual risk.

It applies to software created, modified, integrated, maintained, tested,

assessed, or operated by humans, organizations, automated development
systems, AI coding assistants, autonomous software agents, and
software infrastructure mechanisms.

SSS is technology-independent and does not prescribe a particular
programming language, security tool, development methodology, security
certification scheme, or deployment platform.

Its principal output is:

Governed Software Security State

Its foundational distinction is:

Declared Software Security ≠ Demonstrated Software Security.

Operational Role

The operational role of SSS is:

To ensure that software security requirements, relevant threats and
exposure conditions, protective controls, verification evidence,
vulnerabilities, remediation states, residual risks, and security
acceptance decisions remain identifiable, contextually applicable,
technically assessable, evidence-supported, appropriately authorized,
and traceable to the actual software artifact and configuration
throughout its lifecycle.

SSS provides the security-specific governance layer within SLGA™.

It establishes the conditions under which software security may be
competently evaluated and recognized.

It does not independently authorize software creation, configuration
changes, release, deployment, incident-response operations, or legal
compliance certification.

Core Question

How can software security be defined, demonstrated, assessed, and
accepted through competent evidence while ensuring that implemented
controls, successful scans, closed vulnerability records, or declared
compliance are not mistaken for proof that software is sufficiently
protected against relevant threats under its actual operating
conditions?

Position in Architecture Governance Flow

The SLGA™ governance flow is:

Software Requirements → Software Creation → Software Dependencies →

Software Configuration → Software Quality → Software Security →
Software Release → Software Deployment → Software Change Management →
Software Retirement

Cross-cutting:

Software Lifecycle Control

SSS governs the sixth lifecycle domain:

Software Security

Its upstream governance references include:

Software Requirements Standard (SRS): Governed software
requirements
Software Creation Standard (SCS): Governed software creation and
Software Dependency Standard (SDS): Governed software
dependencies
Software Configuration Standard (SCFS): Governed software
Software Quality Standard (SQS): Governed software quality

artifact provenance. configuration.

Its principal output is:

Governed Software Security State

Downstream consumers may include:

- Software Release Standard (SRLS)

- Software Deployment Standard (SDPS) - Software Change Management
Standard (SCMS) - Software Retirement Standard (SRTS) - Software
Lifecycle Control Standard (SLCS)

The lifecycle sequence establishes governance dependencies, not a

restriction requiring security work to occur only after quality
assessment.

Security requirements, threat analysis, control verification, and

vulnerability treatment may operate throughout the software lifecycle.

Software Security Governance Object

Every material software security determination shall reference an

identifiable Software Security Governance Object.

The object shall preserve, where applicable:

Security Object Identity: The governed software security subject.

Software Object: The component, application, service, or integrated

system.

Artifact Identity: The software artifact actually assessed.

Configuration Reference: The relevant configuration and execution

conditions.

Security Purpose: The protective objectives.

Security Scope: The boundaries of the determination.

Requirements: Applicable software security requirements.

Threat Context: Relevant threats and exposure conditions.

Controls: Applicable protective mechanisms.

Evidence: Verification and assessment records.

Vulnerabilities: Known or suspected security weaknesses.

Residual Risk: Remaining security exposure or uncertainty.

Acceptance: Any competent security acceptance decision.

Governance State: The recognized software security condition.

A software security governance object shall not be replaced by a generic

statement that a product is secure.

Security Declaration ≠ Governed Security Object.

Software Security Governance Principles

SSS establishes the following principles:

Identifiable Security Subject: Every material determination must
concern identifiable software.

Contextual Applicability: Security conditions depend on software purpose,

exposure, configuration, and intended operation.

Explicit Protective Requirements: Material protection objectives must
remain identifiable.

Threat Correspondence: Controls and assessments must correspond to
relevant threat conditions.

Evidence-Based Determination: Security conclusions require competent

supporting evidence.

Verified Control Effectiveness: Control implementation is not proof of
protection.

Vulnerability Transparency: Known vulnerabilities and unresolved findings

remain visible.

Bounded Assurance: Security claims cannot exceed their supporting

Legitimate Acceptance Authority: Security assessment and acceptance of

residual risk remain distinct.

Lifecycle Continuity: Security determinations must survive as
traceable records across changes.

Material Reassessment: Changes in threats, software, configuration, or

exposure may invalidate previous determinations.

Non-Absolute Security: No finite assessment demonstrates invulnerability

against every possible attack.

Software Security Purpose

SSS shall establish the security purpose relevant to the governed
software.

Purposes may include:

Preserving confidentiality
Protecting information integrity
Supporting service availability
Preventing unauthorized actions
Protecting privileged operations
Preventing unauthorized code or configuration modification
Preserving transaction integrity
Protecting communication between software components
Limiting compromise propagation
Supporting secure recovery

The purpose shall remain connected to actual software functions and

protected assets.

Security Objective ≠ Implemented Security Mechanism.

Software Security Scope

SSS shall establish the boundaries of each material security
assessment.

Scope may concern source code, executable artifacts, libraries,
services, interfaces, integrated systems, configurations,
dependencies, and operating environments.

The assessment shall identify relevant inclusions and exclusions.

A component assessment shall not automatically establish security of the

integrated application.

Component Security Assessment ≠ System Security Assurance.

Software Artifact Identity

SSS shall preserve the identity of the artifact to which a security

determination applies.

Relevant references may include:

Artifact identifier
Version
Build identity
Content integrity reference
Dependency composition
Configuration baseline
Assessment environment

A security report concerning one build shall not automatically establish

the security condition of another build.

Security Assessment of Version A ≠ Security Assessment of Version B.

Software Configuration Correspondence

SSS shall preserve the relationship between security evidence and relevant

configuration conditions.

These may include:

Enabled features
Authentication settings
Authorization configuration
Network exposure
Debug interfaces
Cryptographic settings
Runtime privileges
Dependency versions
External integrations

A correctly implemented control may be ineffective when disabled or
misconfigured.

Security Control Presence ≠ Active Security Protection.

Security Requirement Governance

SSS shall establish identifiable security requirements relevant to software

behavior and protection.

Requirements may concern authentication, authorization, data
protection, input handling, secure communications, integrity
verification, resilience, security logging, and prevention of
unauthorized execution.

Each material requirement should identify its purpose, applicability,
scope, relevant software object, and verification expectations.

Defined Security Requirement ≠ Demonstrated Security.

Security Requirement Applicability

SSS shall determine which security requirements apply to the actual

software context.

Applicability may depend on protected assets, intended use, user
privileges, integration relationships, deployment conditions, and
relevant threats.

Requirements shall not be treated as universally applicable without
context.

General Security Requirement ≠ Applicable Security Requirement.

Security Requirement Traceability

SSS shall preserve traceability between requirements, protective controls,

verification evidence, vulnerabilities, and security determinations.

The reference relationship is:

Security Requirement → Relevant Threat or Property → Protective Control →

Verification → Evidence → Security Determination

Traceability alone does not establish satisfaction.

Traceable Security Requirement ≠ Verified Security Requirement.

Security Assumption Governance

SSS shall identify material assumptions on which security conclusions

depend.

Examples include:

Trusted network segmentation
Correct identity-provider behavior
Protected signing keys
Secure infrastructure configuration
Trusted external services
Limited administrative access
Correct dependency behavior

Assumptions must remain distinguishable from verified conditions.

Where a material assumption is invalidated, affected security
conclusions shall be reassessed.

Assumed Protection ≠ Demonstrated Protection.

Protected Asset Identification

SSS shall identify assets requiring protection.

Assets may include:

Personal information
Financial records
Authentication credentials
Cryptographic keys
Operational commands
Business-sensitive information
Software integrity
Service availability
Critical application functions

Asset identification provides the basis for evaluating security

consequences.

Protected Asset Importance ≠ Vulnerability Severity.

Security Property Governance

SSS shall establish the relevant security properties of the software.

These may include:

Confidentiality
Integrity
Availability
Authenticity
Authorization correctness
Isolation
Resistance to unauthorized modification
Recovery integrity

A property shall be associated with assessable conditions where
technically feasible.

Declared Security Property ≠ Verified Security Property.

Trust Boundary Governance

SSS shall identify material trust boundaries within and around the
software.

Examples include boundaries between users and applications, services and

databases, internal and external APIs, development and production
systems, and autonomous agents and accessible tools.

A trust boundary shall remain associated with relevant authentication,

authorization, data handling, and control requirements.

Technical Access Across a Boundary ≠ Legitimate Authority.

Threat Identification

SSS shall recognize identifiable threat conditions relevant to the
software.

Threats may include:

Unauthorized access
Credential compromise
Injection attacks
Privilege escalation
Data manipulation
Service disruption
Malicious dependency behavior
Unauthorized software modification
Abuse of privileged interfaces

Identifying a possible threat does not establish that the threat has
been realized.

Identified Threat ≠ Observed Attack.

Threat Applicability

SSS shall assess whether a threat is relevant to the software object,
configuration, exposure, and operating environment.

Threat applicability may depend on attack-surface accessibility,
privileges, dependencies, protected assets, and trust boundaries.

A theoretical threat pattern shall not automatically be represented as an

actual software exposure.

Known Threat Pattern ≠ Demonstrated Exposure.

Threat Modeling Governance

SSS shall govern the evidentiary use of threat models.

A material threat model should identify:

Software scope
Protected assets
Trust boundaries
Relevant assumptions
Threat scenarios
Potential attack paths
Applicable controls
Known limitations

Threat modeling supports security analysis but does not substitute for
verification.

Completed Threat Model ≠ Demonstrated Software Security.

Attack Surface Identification

SSS shall identify relevant points through which software may be
accessed, influenced, or attacked.

Attack surfaces may include:

Public APIs
Authentication endpoints
Administrative interfaces
File-processing functions
Network services
Update mechanisms
External integrations
Agent-accessible tools
Plugin interfaces

An attack surface is not automatically a vulnerability.

Attack Surface ≠ Confirmed Vulnerability.

Security Exposure Assessment

SSS shall assess the conditions under which relevant threats may reach
the software.

Exposure may depend on:

Network accessibility
User privileges
Enabled functionality
Configuration
Deployment environment
External dependencies
Available mitigations

Exposure shall remain distinguishable from exploitability and observed

exploitation.

Security Exposure ≠ Demonstrated Exploitation.

Security Control Definition

SSS shall establish identifiable protective controls corresponding to

applicable security requirements and threats.

Controls may include authentication, authorization, input validation,
output encoding, cryptographic protection, isolation, integrity
verification, rate limiting, secure configuration, and security
logging.

Controls shall remain connected to the protective purpose they are
intended to serve.

Defined Security Control ≠ Implemented Security Control.

Security Control Applicability

SSS shall determine whether a selected control is suitable for the
relevant security conditions.

Applicability depends on the protected asset, threat model, software

architecture, trust boundary, and operating environment.

A generally recommended control may be insufficient for a particular
risk.

Recommended Control ≠ Sufficient Protection.

Security Control Implementation

SSS shall preserve evidence that the required control exists in the
relevant software artifact or configuration.

Evidence may include code references, configuration records, build
references, deployment settings, and integration records.

Implementation evidence shall not be treated as proof of
effectiveness.

Implemented Security Control ≠ Verified Security Control.

Security Control Effectiveness

SSS shall assess whether a control provides the intended protection under

relevant conditions.

Verification should consider:

Applicable threats
Correct artifact
Relevant configuration
Suitable assessment method
Expected protective behavior
Observed protective behavior
Known limitations

A control that executes successfully may still fail to prevent the
relevant attack.

Successful Control Execution ≠ Demonstrated Protective Effectiveness.

Security Architecture Correspondence

SSS shall preserve correspondence between documented security architecture

and the implemented software.

Relevant relationships include component boundaries, authentication paths,

authorization checks, data flows, dependency interactions, and
external interfaces.

Architectural documentation shall not be treated as independent evidence

that the implemented system conforms.

Documented Security Architecture ≠ Verified Security Implementation.

Authentication Security

SSS shall govern the security assessment of software mechanisms used to

establish and verify identity.

Relevant conditions include credential validation, session handling, token

verification, authentication failure behavior, and identity-provider
integration.

Successful authentication shall not automatically authorize subsequent

actions.

Authenticated Identity ≠ Authorized Action.

Authorization Security

SSS shall assess whether software operations are constrained by
applicable permissions.

This includes:

Resource access
Role boundaries
Delegated permissions
Privileged functions
Agent tool access
Data access
Constituent action authorization

Authority for an objective does not automatically authorize every
action used to achieve it.

Task Authority ≠ Constituent Action Authority.

SSS governs technical enforcement and verification.

General legitimacy of authority remains governed by competent

authority-governance mechanisms.

Data Protection Security

SSS shall assess security conditions protecting data processed,

transmitted, or stored by software.

Relevant conditions include access restrictions, confidentiality,

integrity, secure transmission, secure storage, and prevention of
unintended disclosure.

The existence of encryption does not establish comprehensive data
protection.

Encrypted Data ≠ Fully Protected Data.

Input and Output Security

SSS shall govern security-relevant handling of inputs and outputs.

Relevant conditions may include input validation, parsing, injection
resistance, output encoding, file handling, command construction, and
error disclosure.

Successful processing of valid inputs shall not establish resistance to

malicious inputs.

Functional Input Handling ≠ Secure Input Handling.

Software Interface Security

SSS shall assess security conditions governing software interfaces.

Interfaces may include APIs, administrative endpoints, plugin
interfaces, service connections, and autonomous agent tools.

The ability to exchange information or execute operations does not
establish that the interface is appropriately protected.

Functional Interface ≠ Secure Interface.

Dependency Security Correspondence

SSS shall preserve security-relevant relationships with software

dependencies.

Relevant considerations include:

Known vulnerabilities
Affected component versions
Transitive dependencies
Dependency privileges
Reachable vulnerable functionality
Security update availability
Relevant integration behavior

SDS governs dependency identity, origin, suitability, and continuity.

SSS governs the security consequences of those dependencies.

Identified Dependency ≠ Security-Verified Dependency.

Configuration Security

SSS shall assess whether the relevant software configuration supports

applicable security conditions.

Examples include:

Default credentials
Exposed debug services
Excessive privileges
Disabled protective mechanisms
Insecure network settings
Weak cryptographic configuration

SCFS governs configuration identity and integrity.

SSS governs security characteristics of the configuration.

Configuration Integrity ≠ Secure Configuration.

Software Supply-Chain Security Evidence

SSS shall recognize security-relevant evidence concerning software

components, artifacts, and build processes.

Evidence may include:

Component provenance
Artifact integrity
Build references
Dependency vulnerability findings
Signing records
Compromise indicators

Provenance and integrity evidence are important but do not establish
the absence of vulnerabilities.

Verified Software Origin ≠ Verified Software Security.

Secrets Handling Security

SSS shall assess software handling of sensitive secrets.

Secrets may include API keys, access tokens, signing credentials,
cryptographic keys, and service passwords.

Relevant conditions include storage, access, transmission, rotation,

revocation, and exposure.

The presence of a secrets-management system does not independently
demonstrate secure handling.

Secrets Management Tool ≠ Demonstrated Secrets Protection.

Security Testing Governance

SSS shall govern the security-specific purpose, scope, suitability, and

interpretation of software security testing.

Testing methods may include:

Static analysis
Dynamic analysis
Dependency scanning
Configuration assessment
Penetration testing
Fuzz testing
Security regression testing
Targeted vulnerability verification

Security testing must remain connected to applicable requirements and
threats.

Security Testing Completed ≠ Software Security Demonstrated.

Security Testing Scope

SSS shall identify the boundaries of security testing.

Scope may include artifact versions, interfaces, threat classes,
privilege conditions, configurations, environments, and exclusions.

A test result shall not be generalized beyond the conditions actually

assessed.

Tested Attack Surface ≠ Complete Attack Surface.

Security Assessment Method Suitability

SSS shall assess whether a security testing method is suitable for the
claim it is intended to support.

Static analysis may identify potentially insecure code patterns
without demonstrating runtime exploitability.

Dependency scanning may identify vulnerable versions without
establishing that vulnerable functionality is reachable.

Penetration testing may demonstrate resistance to selected attack
paths without establishing resistance to every possible attack.

Security Test Execution ≠ Sufficient Security Verification.

Security Testing Coverage

SSS shall evaluate security testing coverage against relevant requirements,

threats, attack surfaces, and operating conditions.

Coverage may concern:

Security properties
Threat scenarios
Privileged operations
Exposed interfaces
Critical software functions
Relevant configurations

Numerical coverage alone shall not establish adequate security
assurance.

High Security Test Coverage ≠ Proof of Software Security.

Security Evidence Governance

SSS shall preserve competent evidence supporting security
determinations.

Evidence may include:

Security requirements
Threat models
Control verification
Security test records
Vulnerability findings
Remediation evidence
Configuration references
Security acceptance decisions

Evidence must remain associated with the software artifact and
security condition assessed.

Security Evidence Present ≠ Security Evidence Sufficient.

Security Evidence Competence

SSS shall assess whether evidence is suitable for the security
conclusion being made.

Competence depends on relevant artifact identity, configuration, threat

conditions, testing method, assessment scope, and known limitations.

A successful security scan against a different artifact is
insufficient to establish security of the intended artifact.

Successful Scan ≠ Competent Security Evidence.

Security Evidence Integrity

SSS shall preserve material security evidence integrity.

Relevant conditions may include:

Evidence source
Assessment identity
Artifact correspondence
Record integrity
Temporal relevance
Material contradictions
Preservation of historical findings

An intact report may still support an invalid or overly broad
conclusion.

Intact Security Report ≠ Valid Security Determination.

Vulnerability Identification

SSS shall establish identifiable references for potential software

vulnerabilities.

Findings may originate from testing, scanning, research disclosures,
operational observations, incident investigation, human review, or
automated analysis.

A reported vulnerability shall remain distinguishable from a confirmed

vulnerability.

Vulnerability Report ≠ Confirmed Vulnerability.

Vulnerability Confirmation

SSS shall establish the conditions under which available evidence supports

recognition of a vulnerability in the relevant software.

Confirmation may require:

Affected artifact correspondence
Relevant vulnerability conditions
Applicable configuration
Technical evidence
Exposure assessment
Reproducible behavior where feasible

A vulnerable dependency version does not automatically establish
exploitable application behavior.

Known Vulnerable Component ≠ Demonstrated Exploitable Application.

Vulnerability Classification

SSS shall classify material vulnerabilities by technical
characteristics.

Categories may include injection, authentication weaknesses,
authorization weaknesses, data exposure, memory safety failures,
cryptographic weaknesses, insecure configuration, and dependency
vulnerabilities.

Classification shall remain distinct from severity.

Vulnerability Type ≠ Vulnerability Severity.

Vulnerability Severity

SSS shall assess the potential technical significance of confirmed

vulnerabilities.

Severity may depend on affected security properties, required
privileges, attack complexity, and potential consequences.

Severity alone shall not determine treatment priority.

Vulnerability Severity ≠ Remediation Priority.

Vulnerability Exploitability

SSS shall assess the conditions under which a vulnerability may be
exploited.

Relevant considerations include:

Reachability
Required privileges
Attack complexity
Configuration
Available mitigations
Dependency behavior

Potential exploitability shall not be confused with observed
exploitation.

Potential Exploitability ≠ Observed Exploitation.

Vulnerability Exposure

SSS shall evaluate the extent to which relevant vulnerability conditions

are accessible.

Exposure may depend on network accessibility, enabled functionality,
user privileges, deployment scope, and integration conditions.

A high-severity vulnerability may have limited exposure.

A lower-severity vulnerability may have extensive exposure.

Vulnerability Severity ≠ Actual Exposure.

Vulnerability Impact

SSS shall assess actual or reasonably supported consequences of material

vulnerabilities.

Consequences may include unauthorized access, data disclosure, service
disruption, data modification, privilege escalation, or software
compromise.

Potential impact shall remain distinguishable from demonstrated harm.

Potential Security Impact ≠ Observed Security Harm.

Vulnerability Prioritization

SSS shall govern vulnerability treatment priority.

Prioritization may consider:

Severity
Exploitability
Exposure
Protected assets
Operational consequences
Available mitigations
Remediation feasibility
Relevant dependencies

A single numerical score shall not substitute for contextual
assessment.

Severity Score ≠ Complete Security Risk Determination.

Vulnerability Remediation

SSS shall preserve references to vulnerability remediation actions.

Actions may include code correction, dependency updates, configuration
changes, stronger controls, interface restrictions, removal of
vulnerable functionality, or compensating measures.

Implementation of a corrective action shall remain distinguishable from

verified remediation.

Remediation Implemented ≠ Vulnerability Resolved.

Remediation Authority

SSS shall preserve relevant authorization references for security

remediation.

Authority may concern source-code changes, dependency updates,
configuration modifications, emergency interventions, or production
access.

Identification of a vulnerability does not independently authorize
changes to production software.

Authority to Identify a Vulnerability ≠ Authority to Modify Production

Remediation Verification

SSS shall require competent evidence before material remediation is
recognized as verified.

Verification may include:

Reassessment of the original vulnerability
Corrected artifact identification
Configuration correspondence
Relevant security testing
Verification of expected protective behavior
Assessment of remaining exposure

Closing a vulnerability ticket shall not independently establish verified

resolution.

Vulnerability Closure ≠ Verified Vulnerability Remediation.

Security Regression Governance

SSS shall recognize security regression risks arising from corrective

actions or software changes.

Regression assessment may concern authentication, authorization, input
handling, data protection, dependency interactions, and existing
controls.

Correction of one vulnerability does not establish that all other
security properties remain unaffected.

One Vulnerability Resolved ≠ Absence of Security Regression.

Residual Security Risk

SSS shall identify material security risk remaining after protective

controls, assessment, and remediation.

Residual risk may arise from:

Known unresolved vulnerabilities
Incomplete control verification
Unassessed attack surfaces
Operational exposure
Unsupported configurations
Incomplete remediation
Threat uncertainty

Residual risk identification shall remain separate from risk
acceptance.

Residual Risk Identification ≠ Residual Risk Acceptance.

Security Exception Governance

SSS shall recognize explicitly authorized exceptions to security

requirements or treatment expectations.

Exceptions may concern deferred remediation, temporary compensating
controls, restricted use, or time-limited exposure.

Each material exception should preserve:

Exception identity
Scope
Justification
Authority
Conditions
Duration
Reassessment triggers

An authorized exception does not establish that the underlying
security requirement has been satisfied.

Authorized Security Exception ≠ Security Conformity.

Security Conformity Governance

SSS shall establish supported determinations of conformity with applicable

security requirements.

Possible outcomes include:

Conforming: Competent evidence supports satisfaction of the applicable

security conditions.

Partially Conforming: Some applicable conditions are supported while
others remain unmet or unresolved.

Nonconforming: Competent evidence demonstrates failure to satisfy

applicable conditions.

Inconclusive: Available evidence is insufficient for determination.

Not Assessed: Relevant conditions have not been evaluated.

Conformity shall remain distinct from acceptance of residual risk.

Security Conformity ≠ Security Risk Acceptance.

Security Acceptance Authority

SSS shall preserve the legitimate authority under which residual security

conditions may be accepted.

Authority may derive from organizational governance, delegated
responsibility, contractual arrangements, or applicable institutional
procedures.

Technical security expertise alone does not establish acceptance
authority.

Security Assessment Competence ≠ Security Acceptance Authority.

Security Risk Acceptance

SSS shall govern the security-specific basis for accepting residual
risk.

A competent acceptance decision should identify:

Software artifact and configuration
Applicable security requirements
Relevant vulnerabilities
Residual risk
Supporting evidence
Acceptance authority
Decision scope
Conditions and restrictions
Validity boundaries
Reassessment triggers

Security acceptance shall not be represented as proof of
invulnerability.

Security Acceptance ≠ Proof of Software Invulnerability.

Conditional Security Acceptance

SSS shall recognize explicitly bounded acceptance where competent
authority permits it.

Conditions may include restricted use, limited deployment context,
compensating controls, remediation deadlines, additional monitoring,
or mandatory reassessment.

Conditional acceptance does not establish complete conformity.

Conditional Security Acceptance ≠ Complete Security Conformity.

Security Uncertainty

SSS shall preserve uncertainty affecting material security
conclusions.

Uncertainty may arise from incomplete threat information, unverified
controls, limited testing, unknown exploitability, incomplete artifact
correspondence, or changing operating conditions.

Uncertainty shall not be silently converted into security assurance.

Unresolved Security Evidence ≠ Demonstrated Security.

Security Conflict

A Security Conflict exists where material security evidence, findings,
or decisions are incompatible.

Examples include contradictory vulnerability assessments, conflicting

control verification results, incompatible artifact references, or
inconsistent acceptance decisions.

SSS shall preserve the conflict and supporting evidence.

Conflicting Security Evidence ≠ Permission to Select the Preferred

Security Evidence Gap

A Security Evidence Gap exists where material information required for
competent security assessment remains unavailable or insufficient.

Examples include missing control verification, incomplete security testing,

unknown affected artifact, missing remediation evidence, or unresolved
dependency exposure.

A gap does not automatically prove either security or insecurity.

Security Evidence Gap ≠ Proof of Security Sufficiency or Failure.

Critical Security Gap

A Critical Security Gap exists where missing or unresolved evidence
prevents competent determination of a materially consequential
software security condition.

Examples include:

A privileged function without verified authorization controls
A critical vulnerability with unverified remediation
An exposed interface with unresolved authentication behavior
A release candidate tested under a different artifact identity
An autonomous agent with production modification capabilities
but

unresolved permission boundaries.

A critical gap prevents unsupported positive security determinations for

the affected scope.

It does not independently establish that an attack occurred.

Critical Security Gap ≠ Confirmed Security Incident.

Security Continuity

SSS shall preserve security relationships across software versions,

configurations, dependencies, environments, and lifecycle transitions.

Continuity may include:

Security requirements
Threat models
Control verification
Vulnerability history
Remediation evidence
Residual risk
Security exceptions
Acceptance decisions
Reassessment records

Historical security conclusions shall not automatically remain valid after

material changes.

Historical Security Assessment ≠ Current Security Assurance.

Security Reassessment

SSS shall support reassessment when material security conditions
change.

Triggers may include:

Newly discovered vulnerabilities
Dependency updates
Software modifications
Configuration changes
New attack surfaces
Changed threat exposure
New operational environments
Compromised credentials
Invalidated controls
Expired exceptions
Contradictory evidence

Reassessment shall preserve relevant historical records.

Security Reassessment ≠ Historical Evidence Erasure.

Software Security Governance States

SSS shall support identifiable governance states, including:

Requirements-Pending: Material security requirements remain undefined.

Exposure-Assessment-Pending: Relevant threat exposure has not been

sufficiently assessed.

Controls-Defined: Applicable controls have been identified.

Controls-Implemented: Relevant controls have been implemented.

Control-Verification-Pending: Effectiveness remains unverified.

Remediation-Implemented: A corrective action has been implemented.

Remediation-Verification-Pending: Remediation effectiveness remains

unverified.

Remediation-Verified: Competent evidence supports remediation within
the assessed scope.

Security-Conforming: Applicable security conditions are sufficiently
supported.

Partially-Conforming: Only part of the applicable conditions is
sufficiently supported.

Security-Nonconforming: Competent evidence demonstrates failure to

satisfy applicable requirements.

Security-Accepted: Competent authority has accepted the assessed security

state.

Conditionally-Accepted: Acceptance is subject to explicit conditions.

Acceptance-Suspended: Reliance on a previous acceptance has been

suspended.

Acceptance-Withdrawn: A previous acceptance has been withdrawn.

Conflict-Detected: Material security evidence is incompatible.

Critical-Gap: A materially consequential security condition lacks

sufficient evidence.

Reassessment-Required: Material changes require renewed evaluation.

Unresolved: Available information does not support a sufficient
determination.

Control, verification, conformity, and acceptance states shall remain

distinguishable.

Security Control State ≠ Security Verification State ≠ Security Acceptance

SSS Core Module Architecture

SSS is implemented through five Core Modules. Module 1 — SRQM —
Security Requirements Module

Governed Mechanism: Identification, applicability, specification,

protective objectives, security properties, authorization references,
and traceability of software security requirements.

Principal Output: Governed Software Security Requirements State

Foundational Distinction: Defined Security Requirements ≠ Demonstrated

Security.

SRQM establishes which software security conditions must be governed.

It does not independently determine whether those conditions have been
satisfied. Module 2 — SEAM — Security Exposure Assessment Module

Governed Mechanism: Protected assets, threat identification, threat

applicability, trust boundaries, attack surfaces, exposure conditions,
threat modeling, and contextual security exposure.

Principal Output: Governed Software Security Exposure State

Foundational Distinction: Identified Threat ≠ Demonstrated Software

Exposure.

SEAM establishes the relevant security exposure conditions.

It does not independently establish control effectiveness or
vulnerability remediation. Module 3 — STCM — Security Testing &
Control Module

Governed Mechanism: Security control applicability, implementation

correspondence, effectiveness verification, security testing,
coverage, assessment method suitability, and supporting evidence.

Principal Output: Governed Software Security Testing & Control State

Foundational Distinction: Implemented Security Control ≠ Verified

Security Control Effectiveness.

STCM establishes the evidentiary relationship between protective controls,

threat conditions, and observed security behavior.

It does not independently accept residual security risk. Module 4 —
VMM — Vulnerability Management Module

Governed Mechanism: Vulnerability identification, confirmation,

classification, severity, exploitability, exposure, impact,
prioritization, remediation references, remediation verification, and
continuity.

Principal Output: Governed Software Vulnerability State

Foundational Distinction: Vulnerability Closure ≠ Verified Vulnerability

VMM establishes the governance conditions under which software

vulnerabilities are recognized, assessed, treated, and verified.

It does not independently establish complete software security. Module
5 — SRCM — Security Risk & Conformity Module

Governed Mechanism: Security conformity assessment, residual risk

evaluation, security exceptions, acceptance eligibility, acceptance
authority, conditional acceptance, evidence sufficiency, acceptance
validity, and reassessment.

Principal Output: Governed Software Security Risk & Conformity State

Foundational Distinction: Security Acceptance ≠ Proof of Software

Invulnerability.

SRCM establishes the conditions under which software security conformity

and residual security risk acceptance can be competently determined
within explicit boundaries.

It does not independently authorize software release or deployment.

SSS Module Governance Flow

The canonical module governance flow is:

Security Requirements

↓

Security Exposure Assessment

↓

Security Testing & Control

↓

Vulnerability Management

↓

Security Risk & Conformity

↓

Governed Software Security State

The flow represents governance dependencies rather than a mandatory

one-pass technical workflow.

New vulnerabilities may require revised exposure assessment.

Changes in threat conditions may require revised security
requirements.

Failed control verification may require changes to protective
mechanisms.

Remediation may require renewed security testing.

Residual risk findings may require additional controls, restrictions,
or reassessment.

The modules therefore form an iterative governance system.

Cross-Architecture Boundary

SSS governs software-specific security requirements, exposure assessment,

protective controls, security testing, vulnerability management,
remediation verification, residual security risk, and security
conformity and acceptance within SLGA™.

It does not independently govern organization-wide cybersecurity
strategy, enterprise information security management, physical
security, legal compliance certification, incident-response command,
or general organizational risk acceptance beyond software security.

Within SLGA™:

Software Requirements Standard (SRS) governs software requirements.

Software Creation Standard (SCS) governs software creation.

Software Dependency Standard (SDS) governs software dependencies.

Software Configuration Standard (SCFS) governs software configuration.

Software Quality Standard (SQS) governs software quality.

Software Security Standard (SSS) governs software security.

Software Release Standard (SRLS) governs software release.

Software Deployment Standard (SDPS) governs software deployment.

Software Change Management Standard (SCMS) governs software lifecycle

changes.

Software Retirement Standard (SRTS) governs software retirement.

Software Lifecycle Control Standard (SLCS) governs cross-cutting

lifecycle control.

Relevant interoperating OOF® architectures include:

GOA™ — Governance Architecture: General authority, delegation, and

governance boundaries.

AGA™ — Accountability Governance Architecture: Relevant responsibility

and accountability relationships.

ORA™ — Operational Reality Architecture: Assessment of actual operating

conditions and evidence correspondence.

ASGA™ — Autonomous Systems Governance Architecture: Relevant autonomous

system behavior and control boundaries.

AGI™ — Agent Governance Infrastructure: Agent permissions, delegated

authority, tool-path governance, and constituent action authorization.

OBIDENITY® — Origin-Bound Identity Governance Architecture®: Relevant

identity, origin, ownership, provenance, and continuity relationships.

SSS governs the software security conditions associated with these

relationships without replacing their competent architectural domains.

Canonical Boundary

SSS begins when a software object requires the establishment,
assessment, verification, treatment, acceptance, or reassessment of
software security conditions.

SSS governs:

Software security identity
Security purpose and scope
Artifact and configuration correspondence
Security requirements
Security assumptions
Protected assets
Security properties
Trust boundaries
Threat identification and applicability
Threat modeling
Attack surfaces
Security exposure
Protective controls
Control applicability and implementation
Control effectiveness
Security architecture correspondence
Authentication and authorization security
Data and interface protection
Dependency and configuration security
Software supply-chain security evidence
Secrets handling
Security testing and coverage
Security evidence competence and integrity
Vulnerability identification and confirmation
Vulnerability classification, severity, exploitability,
exposure, and
Vulnerability prioritization
Remediation and remediation verification
Security regression
Residual security risk
Security exceptions
Security conformity
Security acceptance authority
Conditional acceptance
Security uncertainty and conflicts
Security evidence gaps
Critical security gaps
Security continuity and reassessment
Software security governance states

impact.

SSS does not independently determine:

Enterprise cybersecurity strategy
Organization-wide information security governance
Physical security
Software creation authorization
Dependency origin validity
Configuration baseline integrity
Complete software quality
General software change authorization
Incident response command
Release authorization
Deployment authorization
Legal compliance
Legal liability

SSS ends when material software security conditions have been
represented as a:

Governed Software Security State

with sufficient software identity, security requirements, threat and

exposure context, protective control evidence, testing evidence,
vulnerability and remediation states, residual risk, acceptance
conditions, uncertainty, and lifecycle continuity information for
competent downstream governance.

Canonical Closing Statement

Software security cannot be established merely by implementing protective

controls, completing security scans, closing vulnerability tickets, or
declaring that a system is secure.

A security requirement may be documented without being satisfied.

A control may be implemented without providing effective protection.

A vulnerability may remain undetected despite extensive testing.

A reported remediation may remain unverified in the executable
artifact.

A component may appear secure in isolation while becoming exposed
through integration, configuration, dependencies, or operational
conditions.

And a previously accepted security state may become insufficient when
threats, vulnerabilities, software, or operating conditions change.

Declared Software Security ≠ Demonstrated Software Security.

Implemented Security Control ≠ Verified Security Control
Effectiveness.

Security Testing Completed ≠ Software Security Demonstrated.

Vulnerability Closure ≠ Verified Vulnerability Remediation.

Security Conformity ≠ Security Risk Acceptance.

Security Acceptance ≠ Proof of Software Invulnerability.

These distinctions are especially important as AI coding assistants
and autonomous agents increasingly generate software, select
dependencies, modify configurations, execute security tests, and
propose remediation.

An autonomous system may produce convincing security evidence without
demonstrating that the evidence is sufficient.

It may identify a vulnerability without possessing authority to modify
production software.

It may report successful remediation without verifying the corrected
artifact.

And it may recommend acceptance without possessing legitimate
authority to accept residual security risk.

The actor may change. The requirement for legitimate authority does
not.

SSS therefore governs the evidentiary relationship between software

security requirements, actual exposure, protective controls, observed
behavior, vulnerabilities, remediation, residual risk, and security
acceptance.

It does not promise absolute security.

It establishes the methodological conditions under which security claims

may be competently assessed, appropriately bounded, and preserved
throughout the software lifecycle.

SSS transforms software security from a collection of controls, scans,

vulnerability records, and compliance declarations into a governed,
evidence-supported security state — establishing which protective
conditions were required, which threats were relevant, which controls
were verified, which vulnerabilities remain, what residual risk
exists, and under whose legitimate authority that risk has been
accepted.

Software security is not governed because a system has been declared
secure. It is governed when its requirements, exposure, controls,
verification evidence, vulnerability conditions, residual risks,
acceptance boundaries, and lifecycle continuity remain sufficiently
established for competent security governance.
