Improve the Safeguards

I l @ ve RuBoard

If the incident could have been prevented by implementing safeguards, then those safeguards should be implemented, if they are financially justifiable, even if the vulnerability is repaired. Once a vulnerability is discovered, it is probable that other similar vulnerabilities will also be discovered . Implementing a safeguard may prevent incidents based on similar vulnerabilities that have not yet been reported .

Improving safeguards includes changes to existing safeguards and adding new ones. Safeguards can be either technical or procedural.

Review Safeguards

All safeguards should be reviewed and their configurations adjusted based on the information gained from the incident. Evaluate whether there needs to be an adjustment to security procedures to maintain the configurations of these safeguards as new vulnerabilities are discovered or new services are added.

Add Safeguards

Evaluate if there is a need for additional safeguards in locations that were not anticipated, but which the incident brought to light. Determine if there is a need for new safeguards to protect new services or new locations.
