The technique used after a security breach and intended to limit the extent of any damage caused by the incident is called corrective controls.
Corrective controls are a set of procedures, processes, or techniques implemented after a security incident has occurred to mitigate the damage caused by the incident. They help restore systems and data to a normal and secure state. Corrective controls typically include the following:
Containment: The first step is to contain the damage and prevent it from spreading further. This is done by isolating affected systems, disconnecting them from the network, and disabling any access that the attacker may have gained.
Eradication: Once the damage is contained, the next step is to eliminate the cause of the security breach. This involves identifying the source of the attack and removing any malicious code or software that may have been installed.
Recovery: The third step is to recover from the damage caused by the security incident. This includes restoring any lost data or system functionality, and testing to ensure that the system is fully operational and secure.
Lessons learned: Finally, it is important to analyze the incident and identify any weaknesses in the security controls that allowed the breach to occur. This analysis can help prevent similar incidents from happening in the future.
In contrast, preventive controls are designed to prevent security incidents from occurring in the first place. Examples of preventive controls include firewalls, access controls, and security policies.
Detective controls are used to detect security incidents as they occur. Examples of detective controls include intrusion detection systems, log analysis, and security audits.
Safeguards refer to any measures taken to protect information or assets. This includes preventive controls, detective controls, and corrective controls.
In summary, corrective controls are the set of procedures, processes, or techniques implemented after a security incident has occurred to mitigate the damage caused by the incident.
