Incident Response Plan: Complete Building Guide
Breach happened — what do you do in the first 30 minutes? An incident response plan defines roles and steps in advance. We explain how to build one.
Why You Need an Incident Response Plan
The question is not "will you experience a security incident?" — the question is "when?" The average cost of security incidents for companies in the Middle East: $8.07 million (IBM 2024 report). Companies with a prepared response plan save $2.66 million compared to those without one.
An Incident Response Plan (IRP) is a document that defines exactly: who acts, how they act, and when — the moment a security incident is discovered.
The Six Phases of Incident Response
Phase 1: Preparation
This is the most important phase — and it happens before any incident.
Tasks:
- Define the response team and each member's role
- Document emergency contact numbers
- Set up forensic investigation tools
- Identify critical assets and rank them by importance
- Train the team on different scenarios
- Configure monitoring and alerting systems
Critical Assets — Rank Them:
| Priority | Asset | Reason |
|---|---|---|
| 1 | Customer database | Personal data + PDPL compliance |
| 2 | Payment systems | Financial data |
| 3 | Production servers | Service continuity |
| 4 | Communication | |
| 5 | Website | Reputation |
Phase 2: Detection and Analysis
How do you know an incident is occurring?
Indicators of Compromise (IoC):
- Abnormal increase in network traffic
- Repeated failed login attempts
- Unknown new files on the server
- Unfamiliar processes running in the background
- Changes to system files
- Alerts from IDS/IPS or antivirus software
Analysis Steps:
- Confirm it is an actual incident, not a false alarm
- Determine the scope: how many systems are affected?
- Identify the incident type: breach, ransomware, data leak
- Assess severity level: low, medium, high, critical
- Document everything from the moment of discovery
Phase 3: Containment
Goal: stop the damage from spreading without destroying evidence.
Short-term Containment:
- Isolate affected systems from the network
- Change compromised passwords immediately
- Block suspicious IP addresses
- Disable compromised accounts
Long-term Containment:
- Move affected systems to an isolated network for investigation
- Apply missing security patches
- Harden clean systems to prevent spread
Phase 4: Eradication
Complete removal of the root cause.
- Delete malicious software
- Close the exploited vulnerability
- Review all connected systems
- Verify no backdoors remain
- Update all credentials
Phase 5: Recovery
Bring systems back to normal operation.
- Restore from clean backups (verify they are not compromised)
- Return systems to production gradually
- Intensive monitoring for at least 72 hours
- Verify all services are functioning normally
Phase 6: Lessons Learned
The most important post-crisis phase — and the most frequently skipped.
- Review meeting within 5 days of the incident
- Document: what happened, how it happened, how we detected it, how we responded
- Update the response plan based on lessons
- Improve monitoring systems to prevent recurrence
Reporting Timeline
| Report | Timeframe | Recipient |
|---|---|---|
| Internal (response team) | Immediate | IT Manager |
| Senior management | Within 1 hour | CEO |
| NCA (if major incident) | Within 1 hour | National Authority |
| Affected customers | Within 72 hours | PDPL requires this |
