A SOC (Security Operations Center) playbook in cybersecurity is a documented set of procedures and guidelines that outlines the steps security analysts should take in response to security incidents and events. The playbook typically includes incident response workflows, escalation procedures, and details on how to isolate and contain security incidents to minimize their impact.
The goal of a SOC playbook is to provide security analysts with a standardized, repeatable process for responding to security incidents, enabling them to quickly and efficiently identify, contain, and remediate security incidents. Playbooks are often tailored to specific types of security incidents and can include details on how to respond to a range of threats, including malware infections, phishing attacks, and unauthorized access attempts.
Overall, a SOC playbook helps to streamline incident response processes, improve consistency and accuracy in response efforts, and enable organizations to better manage and mitigate the impact of security incidents.
What can be found in a SOC playbook?
We just explain that the playbook is an incident response workflow,
An IR (Incident Response) workflow, here are some of the topics included in the SOC playbook:
- Identification: The first step in incident response is to identify a potential security incident. This could be triggered by an alert from a security tool or by an analyst observing suspicious activity.
- Triage: Once an incident has been identified, the next step is to triage it to determine its severity and impact. This could involve reviewing logs and other data to understand the scope of the incident.
- Containment: If the incident is determined to be serious, the next step is to contain it to prevent further damage. This might involve isolating affected systems, disabling network access, or shutting down affected services.
- Investigation: With the incident contained, the investigation can begin in earnest. This might involve gathering additional data, interviewing witnesses, or reviewing system configurations to understand how the incident occurred.
- Remediation: Once the investigation is complete, the next step is to remediate the incident. This could involve patching systems, changing passwords, or reconfiguring security controls to prevent similar incidents from occurring in the future.
- Reporting: Finally, the incident response team should document the incident and report on it to stakeholders, including senior management, legal, and regulatory bodies as required.

What is the best practice methodology for the SOC playbook
Yes, there are several best practice methodologies that organizations can follow when creating a SOC playbook. Some of these methodologies include:
NIST Incident Response Framework The National Institute of Standards and Technology (NIST) provides a framework for incident response that can be used as a basis for creating a SOC playbook. The framework includes a set of guidelines for preparing for, detecting, analyzing, containing, eradicating, and recovering from security incidents.
SANS Incident Response Process The SANS Institute provides a six-step incident response process that can be used as a foundation for a SOC playbook. The steps include preparation, identification, containment, eradication, recovery, and lessons learned.
MITRE ATT&CK Framework The MITRE ATT&CK Framework is a knowledge base of adversary tactics, techniques, and procedures (TTPs) based on real-world observations of cyber attacks. The framework can be used to help identify and respond to security incidents by mapping incident indicators to specific TTPs.
ISO 27035: ISO 27035 is an international standard for information security incident management that provides guidance on incident detection, analysis, containment, eradication, and recovery. The standard can be used as a reference for creating a SOC playbook.
CIS Controls The Center for Internet Security (CIS) provides a set of best practices for securing IT systems and networks. The CIS Controls include a section on the incident response that can be used as a starting point for developing a SOC playbook.
These methodologies provide a structured approach to creating a SOC playbook, but it's important to tailor the playbook to the specific needs and risks of your organization. A good SOC playbook should be reviewed and updated regularly to ensure it remains effective in the face of evolving cyber threats.
