System Assessment
Once a system’s classification dossier is approved, it needs periodic assessment to prove it still meets the requirements of its assigned level.
Why periodic assessment?
A classification dossier sets the protection level a system must reach. But systems change constantly — new applications, new infrastructure, staff turnover — so compliance drifts over time. A TCVN 14423:2025 assessment surfaces that gap before the authorities come to check.
After you have the classification dossier
A system with an approved classification needs periodic re-assessment to stay compliant — not just at the first dossier.
Benchmarked against the approved level
Reviews every management and technical control against the requirement set for the system’s level.
A compliance report & remediation list
Sets out what passed, what didn’t and what to do before the next assessment, prioritised by risk.
