Responsive Control

This is covered in the CompTIA CySA+ course.

"Responsive controls" in a Security Operations Center (SOC) refer to security measures that are implemented after a security incident has been identified and confirmed, outlining specific actions an analyst must take to mitigate the issue, often following a documented procedure within an incident response playbook.

Key points about responsive controls:

Action-oriented:

Unlike preventive controls that aim to stop an attack before it happens, responsive controls focus on taking immediate corrective actions once a breach is detected.

Playbook-driven:

To ensure consistency and efficiency, responsive actions are usually documented in a detailed incident response playbook, guiding analysts through necessary steps depending on the type of incident.

Examples of responsive actions:

Isolating a compromised system from the network

Quarantining a malicious file

Patching a vulnerable system

Resetting user passwords

Blocking suspicious IP addresses

Investigating the root cause of an incident

Restoring data from backups
