The Swiss Cheese Security Pattern
summary
Argues that layered defenses have inevitable holes so security follows a Swiss cheese security pattern rather than an impermeable onion, and recommends secure by design over prescriptive “security first.” Calls for one coherent strategy, logged risk decisions, annual reviews and measurable KPIs (mentions Azure security score), and practical controls: secret stores like Key Vault/HashiCorp Vault, PAM/PIM or JIT roles, network segmentation, backup handling and audit trails. Gives concrete failure modes: exposed backups, VPN-to-SMB access to DBs, and destructive ransomware as primary threats.
