In today’s digital landscape, Security Operations Centers (SOCs) are the frontline defenders against a myriad of cyber threats. To effectively combat these threats, SOCs rely on well-crafted playbooks that provide structured responses to various incidents. In this blog, we’ll explore several SOC playbook examples tailored to real-world cyber threats, highlighting their importance and how they can be implemented to enhance an organization’s cybersecurity posture.

1. Ransomware Playbook
Objective: To quickly identify, contain, and eradicate ransomware infections while minimizing data loss and operational disruption.
Steps:
- Detection and Identification:
- Monitor for unusual file encryption activities.
- Use endpoint detection and response (EDR) tools to identify ransomware signatures.
- Containment:
- Isolate infected systems from the network.
- Disable shared drives and network connections to prevent further spread.
- Eradication:
- Remove ransomware using anti-malware tools.
- Restore affected systems from clean backups.
- Recovery:
- Verify the integrity of restored data.
- Reconnect systems to the network after ensuring they are clean.
- Post-Incident Analysis:
- Conduct a root cause analysis to understand how the ransomware entered the network.
- Update security measures to prevent future incidents.
2. Phishing Attack Playbook
Objective: To detect, respond to, and mitigate the impact of phishing attacks targeting employees.
Steps:
- Detection:
- Monitor email gateways for phishing indicators such as suspicious links or attachments.
- Encourage employees to report suspected phishing emails.
- Containment:
- Block malicious email addresses and domains.
- Quarantine phishing emails to prevent further spread.
- Eradication:
- Remove phishing emails from all affected mailboxes.
- Use anti-phishing tools to scan for and eliminate any residual threats.
- Recovery:
- Reset credentials for compromised accounts.
- Educate affected employees on recognizing phishing attempts.
- Post-Incident Analysis:
- Analyze the phishing email to understand its characteristics.
- Update email filtering rules and employee training programs.
3. Insider Threat Playbook
Objective: To identify, investigate, and mitigate threats posed by malicious or negligent insiders.
Steps:
- Detection:
- Monitor user activities for unusual behavior, such as large data transfers or access to sensitive information.
- Use user and entity behavior analytics (UEBA) tools to detect anomalies.
- Investigation:
- Conduct a thorough investigation to determine the intent and scope of the insider threat.
- Interview relevant personnel and review access logs.
- Containment:
- Restrict access to sensitive systems and data for the suspected insider.
- Implement additional monitoring on the insider’s activities.
- Eradication:
- Remove any malicious software or tools used by the insider.
- Revoke access privileges if necessary.
- Recovery:
- Restore any altered or deleted data.
- Reinforce security policies and access controls.
- Post-Incident Analysis:
- Conduct a detailed review of the incident to identify gaps in security.
- Update insider threat detection and response strategies.
4. Distributed Denial-of-Service (DDoS) Attack Playbook
Objective: To mitigate the impact of DDoS attacks and ensure the availability of critical services.
Steps:
- Detection:
- Monitor network traffic for signs of a DDoS attack, such as unusual spikes in traffic.
- Use intrusion detection systems (IDS) to identify attack patterns.
- Containment:
- Implement rate limiting and traffic filtering to manage the attack.
- Use DDoS mitigation services to absorb and deflect malicious traffic.
- Eradication:
- Identify and block the source of the attack.
- Collaborate with internet service providers (ISPs) to mitigate the attack upstream.
- Recovery:
- Restore normal traffic flow and service availability.
- Conduct a thorough review to ensure all attack vectors are addressed.
- Post-Incident Analysis:
- Analyze the attack to understand its methods and impact.
- Update DDoS protection measures and incident response plans.
5. Malware Outbreak Playbook
Objective: To detect, contain, and eradicate malware infections within the network.
Steps:
- Detection:
- Monitor for signs of malware, such as unusual system behavior or alerts from antivirus software.
- Use threat intelligence feeds to stay informed about new malware variants.
- Containment:
- Isolate infected systems to prevent the spread of malware.
- Disable network connections for affected devices.
- Eradication:
- Use anti-malware tools to remove the infection.
- Conduct a thorough scan of the network to ensure all instances of malware are eliminated.
- Recovery:
- Restore systems from clean backups.
- Verify the integrity of restored data and systems.
- Post-Incident Analysis:
- Investigate how the malware entered the network.
- Update security measures to prevent future infections.
Cado simplifies the development of SOC playbooks by providing automated forensic analysis that can be integrated into incident response workflows. Analysts can use Cado’s platform to map out clear, repeatable procedures for handling incidents, collecting evidence, and escalating threats.
