Incident Response Plan

Identify the Incident

Monitor alerts and logs for unusual activities

Check security tools, logs, or user reports

• Classify the incident severity:
  • 🟢 Low: Minor issue, no impact
  • 🟡 Medium: Some users affected, partial system impact
  • 🔴 High: Full outage, security breach, data compromise

📌 Tools to use:

• Firewall logs
• Cloud monitoring (AWS, GCP, Azure)
• SIEM (Security Information and Event Management)

📌 Activate the Incident Response Team (IRT)

✅ Notify the right team immediately ✅ Assign an Incident Manager to take control ✅ Communicate the issue to leadership & key stakeholders ✅ Set up a dedicated incident Slack/Teams/War Room

📌 Key Contacts:

• Security Team: (Email, Phone)
• IT Operations: (Email, Phone)
• Legal & Compliance: (Email, Phone)
• Public Relations (PR) Team: (If external communication is needed)

Contain the Threat

✅ Block malicious traffic, isolate affected systems ✅ Reset compromised accounts and enforce MFA ✅ Disable access to vulnerable endpoints ✅ Apply temporary patches or firewall rules

📌 Emergency actions:

• Stop affected services (systemctl stop )
• Lock compromised user accounts (passwd -l )
• Network segmentation: block traffic from affected IPs

Investigate the Root Cause

✅ Gather logs from affected systems:

journalctl -u <service> --since "1 hour ago"

✅ Review security logs (SIEM, IDS/IPS, WAF) ✅ Check for unauthorized access or file changes ✅ Analyze compromised accounts, leaked credentials
