Group Policy Modification Incident Response Playbook

This download includes the 6clicks Incident Response playbook for Group Policy Modification

The purpose of a Cyber Security Playbook, or Security Playbook, is to provide all members of an organisation with a clear understanding of their roles and responsibilities regarding cybersecurity – before, during and after a security incident.

Adversaries may modify the configuration settings of a domain to evade defenses and/or escalate privileges in domain environments. Domains provide a centralized means of managing how computer resources (ex: computers, user accounts) can act, and interact with each other, on a network.

The policy of the domain also includes configuration settings that may apply between domains in a multi-domain/forest environment. Modifications to domain settings may include altering domain Group Policy Objects (GPOs) or changing trust settings for domains, including federation trusts.

Remember: If you face an incident, follow IRM, take notes, and do not panic. Contact your CERT immediately if needed.

6 steps are defined to handle security Incidents:

• Preparation: get ready to handle the incident
• Identification: detect the incident
• Containment: limit the impact of the incident
• Remediation: remove the threat
• Recovery: recover to a normal stage
• Aftermath: draw up and improve the process
