OT and ICS Cybersecurity in Saudi Arabia: Meeting NCA OTCC
Industrial environments cannot be secured like an office network. A practical approach to visibility, segmentation and monitoring that respects safety and uptime.
Key takeaways
- Keep the core plan short; put technical detail in scenario playbooks.
- Define severity levels and who has authority at each level.
- Build regulatory and contractual notification timelines into the plan.
- Exercise it — tabletop at least twice a year, technical drills annually.
What a good plan contains
A usable incident response plan is short enough to read during a crisis. It sets out scope, roles, severity definitions, escalation paths, communication rules and links to detailed playbooks. NIST SP 800-61 and ISO/IEC 27035 provide solid reference structures.
Roles and authority
| Role | Responsibility |
|---|---|
| Incident commander | Owns the response, makes decisions, keeps the timeline |
| Technical lead | Directs investigation, containment and eradication |
| Communications lead | Internal, customer and media messaging |
| Legal and compliance | Regulatory notification, evidence and privilege |
| Business owner | Decides service priorities and accepts business risk |
| Scribe | Records actions and decisions with timestamps |
Severity levels
Define three or four levels using business impact, not technical detail: for example, a single infected laptop versus a compromise of the identity platform. Each level should specify who is notified, how quickly, and whether executive or board involvement is required.
Playbooks for likely scenarios
- Ransomware and destructive malware
- Business email compromise and payment fraud
- Compromised privileged or cloud administrator account
- Data breach involving personal data
- Distributed denial of service
- Third-party or supply-chain compromise
Each playbook lists detection sources, triage steps, containment options, evidence to preserve and recovery criteria.
Notification obligations
Saudi organizations should map notification duties in advance: incident reporting expectations from the NCA, sector regulators such as SAMA, and PDPL obligations to notify SDAIA and, where required, affected data subjects of personal data breaches. Confirm current timelines with your legal advisers and record them in the plan.
Evidence handling
Preserve volatile data, logs and disk images before rebuilding systems. Maintain chain-of-custody records and limit access to evidence. Decisions taken in the first hours often determine whether root cause can ever be established.
Exercising the plan
Run tabletop exercises with executives at least twice a year using realistic scenarios, and technical drills with IT and security teams annually. Capture lessons learned, update the plan, and track improvement actions to closure.
Next step: our Cybersecurity Services team writes playbooks and runs executive tabletop exercises.
Frequently asked questions
How long should an incident response plan be?
The core plan is typically 10–20 pages, with separate playbooks for specific scenarios.
Who should own the plan?
Usually the CISO, with sign-off from executive management and input from legal, communications and IT.
Should we have an incident response retainer?
For most organizations, yes. A retainer guarantees specialist support quickly and avoids procurement delays during a crisis.
