Remediation in cybersecurity consists of correcting, closing or neutralising a vulnerability or a threat. vulnerability identified in an information system, network or application.
Why is remediation essential?
-
- Preventing attacks : By correcting vulnerabilities, you considerably reduce the risk of falling victim to a cyber attack.
- Damage limitation : if an attack has already occurred, remediation can limit the consequences and prevent it from happening again.
- Regulatory compliance : numerous regulations (RGPD, NIS 2, etc.) require organisations to implement effective security measures, including remediation.
Typical stages in a remediation process
-
- Identifying vulnerabilities : vulnerabilities and weaknesses in the system, applications or networks are identified during security audits, penetration testing, security analysis or intrusion detection systems.
- Risk assessment : Each identified vulnerability is assessed in terms of potential risk, considering the potential impact of successful exploitation and the likelihood of this occurring.
- Prioritisation Vulnerabilities are classified according to their level of risk. High-risk vulnerabilities are generally treated as a priority
- Choice of solution : a number of options can be considered, including software updates, configuration of firewallapplication of patches, etc.
- Implementation : the chosen solution is executed.
- Monitoring and verification : we check that the vulnerabilities have been corrected and that the system is once again secure.
- Documentation: all stages of the remediation process are documented to facilitate monitoring and audits.
