Context
Rulebases that have grown over years often contain old openings, broad services and temporary exceptions without ownership. This is not just an administrative issue, but a direct increase in attack surface.
A good rulebase review combines technical cleanup with clear ownership and change processes.
Practical focus
- Identify rules without hits and without owners
- Reduce broad any-rules to specific targets
- Separate management and server segments
- Enable logging for critical paths
- Document changes with risk and business context
