Common situations behind “system-theoretic process analysis for security (STPA-Sec)” and the first step
  • A customer or supply-chain audit asks for an ISO 27001 certificate:Define the certification scope and applicable controls, then build records that pass a certification body audit
  • A regulator or industry rule requires stronger information security management:Map the regulatory requirements to an ISO 27001 management system so one set of evidence answers several demands
  • Already certified and want to outsource the annual internal audit:Check auditor qualifications and independence, and whether findings turn into corrective actions
