Security Architecture
Security architecture, katmanlı savunmaları (network, application, data, IAM) ve varlıkları korumak ve risk yönetimini desteklemek için policy, standard ve teknolojilerin entegrasyonunu tanımlar.
Kapsamlı bir security architecture, people, process ve technology genelinde bilgi varlıklarını korumak için governance, risk management ve engineering practices oluşturur. Bu, governance ve policy, reference model ve çoklu katmanlarda bir technical stack'i kapsar: governance/policy layer; network security; application security; data security; identity and access management; endpoint ve cloud security; ve supply chain security. Etkili mimariler, kontrolleri tanınmış standartlara (örn. NIST SP 800-53, ISO/IEC 27001, ISO/IEC 27002, NIST SP 800-160, CSA CCM; SABSA; TOGAF) eşler ve security'yi software development lifecycle (secure SDLC) ve threat modeling (örn. STRIDE, PASTA) içine entegre eder. Risk tabanlı bir yaklaşım, least privilege ve defense-in-depth'i vurgular, net ownership, ölçüm ve monitoring (SIEM, EDR, IAM analytics) ve governance review'lar aracılığıyla sürekli iyileştirme ile birlikte. Architecture artifact'leri, reference diagram, policy mapping, control catalog, data classification scheme ve gelişen tehditlere ve regülasyon gereksinimlerine uyum sağlamak için devam eden bir programı içerir. Education ve awareness, supply chain risk management ve incident response entegrasyonu, business hedefleri ve regülasyon posture ile uyumu sağlayarak mimariyi tamamlar.

❓ Sık sorulan sorular
What is the purpose of a security architecture?
To provide a risk-based blueprint for selecting and implementing security controls that protect critical assets while enabling business operations, governed by policy and continuous improvement.
What frameworks or standards guide security architecture?
Common references include NIST SP 800-53, ISO/IEC 27001/27002, NIST SP 800-160, SABSA, TOGAF, and threat modeling practices (STRIDE, MITRE ATT&CK).
What are typical layers or components?
Governance/policy, network security, application security, data security, identity and access management, endpoint/cloud security, and supply chain security.
How does security architecture relate to risk management?
It translates risk-based requirements into concrete controls, aligns with risk appetite, and enables measurable security outcomes.
What is Zero Trust in this context?
A model that requires verification and least-privilege access for every resource, irrespective of location or network perimeter.
