Por que isso importa para confiança e conformidade

• Early detection through robust logging satisfies the ‘Monitoring and Logging’ control objective, a single control that maps to many frameworks such as NIST CSF Detect and ISO 27001 A.12.4.
• Demonstrates the need for continuous evidence collection on log integrity and review frequency.
• Supports audit readiness by linking monitoring controls to multiple compliance frameworks via the Verisq Common Framework.
