Addressing Technical Complexity:
Security Architecture Alignment: Aligning with a security architecture helps manage the complexity by providing a structured framework for implementing and managing security controls.
Comprehensive Framework: A security architecture ensures that all security controls are integrated and aligned with the organization's overall security strategy, reducing the risk associated with technical complexity.
Steps Involved:
Develop or Adopt a Security Architecture: Use established frameworks such as SABSA, TOGAF, or Zachman.
Implementation: Apply the security architecture across all systems and processes to ensure consistency and integration.
Monitoring and Maintenance: Continuously monitor the security architecture and update it as necessary to address new threats and technologies.
Comparison with Other Options:
Documenting System Hardening Requirements: Important but does not address the overall complexity.
Minimizing Dependency on Technology: Not always feasible and does not fully address the inherent complexity.
Establishing Configuration Guidelines: Helpful but should be part of the broader security architecture.
Best Practices:
Continuous Improvement: Regularly update and improve the security architecture to adapt to evolving threats and technologies.
Training and Awareness: Ensure that all relevant personnel understand the security architecture and their role in maintaining it.
