Which measure best identifies and prevents tampering in sensitive system logs?
Enforce multifactor tokens for every administrative action
Restrict remote connections using firewall rules and monitoring
Apply cryptographic validation with a non-rewritable archival system
Switch to a separate environment for daily backups
Applying cryptographic validation with a non-rewritable archival system ensures that any unauthorized modification to stored records is visible and effectively blocked. Regular backups do not guarantee proof of original content integrity. Network restrictions help block external threats but do not validate stored data. Enhanced authentication guards against unauthorized entry but does not confirm data remains unchanged post-login.
