Documentation and Audit Requirements
Documentation and Audit Requirements
Compliance requires comprehensive documentation demonstrating security controls, implementation details, and ongoing monitoring. Password systems need documentation covering architecture and data flows, security controls and configurations, incident response procedures, change management processes, and regular assessment results. This documentation must be accurate, current, and accessible to auditors.
Audit trails provide essential evidence of compliance and security. Every password-related operation should generate audit records including who performed the action, what action was taken, when it occurred, where (system/location), and why (purpose/authorization). These logs must be tamper-evident, retained according to regulatory requirements, and regularly reviewed for suspicious activity.
