Here are 36 SOC Incident Response Playbooks covering ransomware, phishing, insider threats, API abuse, and cloud misconfigurations. These playbooks provide structured guidance for Preparation, Detection & Analysis, Containment, Eradication, Recovery, and Lessons Learned.
You Should Know:
1. Ransomware Incident Response
- Detection Command (Linux):
sudo grep -r "encrypted" /var/log/
- Containment Steps:
sudo iptables -A INPUT -s <malicious_IP> -j DROP sudo systemctl isolate rescue.target
- Recovery:
ls -la /etc/shadow /etc/passwd Check for unauthorized changes
2. Phishing Attack Response
- Analyze Suspicious Email Headers:
cat email.eml | grep -i "received|from|to|subject"
- Block Malicious Domain:
sudo echo "0.0.0.0 phishing-domain.com" >> /etc/hosts
3. Insider Threat Detection
- Check User Activity:
last -a | grep "username" sudo ausearch -k insider_threat -i
- Monitor File Access:
sudo auditctl -w /etc/passwd -p war -k password_file_access
4. Cloud Misconfiguration Response
- AWS CLI Check for Public S3 Buckets:
aws s3api list-buckets --query "Buckets[].Name" | xargs -I {} aws s3api get-bucket-acl --bucket {} - Azure Security Scan:
Get-AzStorageAccount | Where-Object { $_.NetworkRuleSet.DefaultAction -eq "Allow" }
5. API Abuse Response
- Check Suspicious API Calls:
journalctl -u apache2 | grep "POST /api"
- Rate Limiting with Nginx:
limit_req_zone $binary_remote_addr zone=api_limit:10m rate=10r/s;
What Undercode Say:
A well-structured SOC Incident Response Playbook is critical for mitigating threats efficiently. Automation with tools like Wazuh, Splunk, and ELK Stack enhances detection. Key takeaways:
– Log Analysis: Always check `/var/log/` and Windows Event Viewer.
– Network Isolation: Use `iptables` (Linux) or `netsh` (Windows) to block malicious traffic.
– Forensics: Tools like Autopsy, Volatility, and FTK Imager help in post-incident analysis.
Prediction:
As cyber threats evolve, AI-driven SOC automation will dominate IR workflows, reducing response time from hours to seconds.
Expected Output:
- Linux Commands:
grep,iptables, `auditctl` - Windows Commands:
netsh advfirewall, `Get-WinEvent` - Cloud Security: AWS CLI, Azure PowerShell
- Forensics: Memory analysis with
volatility, disk analysis with `dd`
