Execution Context
This function establishes the foundational security framework for software systems by designing robust controls and measures. The Security Architect defines threat models, data flow protections, and access governance structures early in the development lifecycle. This ensures that security is embedded into the system architecture rather than added as an afterthought, reducing remediation costs and enhancing overall system resilience against evolving cyber threats.
The Security Architect analyzes existing threat landscapes to identify critical vulnerabilities specific to the proposed software design.
Based on this analysis, the architect designs specific security controls such as encryption standards, authentication protocols, and network segmentation rules.
These designed measures are integrated into the system architecture documentation to guide subsequent development teams in implementation.
Operating Checklist
Identify critical assets and potential threat vectors relevant to the software system scope.
Select appropriate security controls including encryption, authentication mechanisms, and network isolation strategies.
Map control implementation points within the high-level system architecture diagrams.
Document all designed measures in the security requirements specification for engineering teams.
