A system dynamically blocking offending IP addresses is an example of a corrective security control because it takes action to fix or neutralize an issue after detecting a potential threat.

Classification of Security Controls:

Preventive Controls: Aim to stop incidents before they occur (e.g., firewalls, access controls).

Detective Controls: Identify and alert on security incidents (e.g., IDS, monitoring tools).

Corrective Controls: Take action to remediate or mitigate the impact of an incident (e.g., dynamic blocking systems).

Dynamic Blocking Control is not a standard category.

Dynamic Blocking:

The described system actively blocks IP addresses after identifying malicious behavior, making it corrective in nature.

Zero-Day Attack Mitigation:

This refers to dealing with unknown vulnerabilities, which is not the primary functionality of dynamic IP blocking.

Incident Response and Mitigation: Emphasizes corrective controls as key measures for neutralizing threats after detection.

Dynamic Protection Mechanisms: Highlights systems like dynamic blocking under the umbrella of corrective controls.
