An organization may wish to review its current technical architecture (whether documented or not) to identify cyber-security related gaps and understand how such gaps can be remediated using efficient and effective technologies and services; without investing time and money developing a reference technical security architecture and framework.
A proper cyber security technical architecture review should ensure the identification of gaps related to: secure networks and systems design and configuration, and security technologies needed to satisfy the organization protection requirements; all in alignment with the organization context (i.e., risk, maturity, technology environment, budget, regulations, contractual obligations, and security policies).
