The much-scrutinised and much-debated NIS2 is already in force. Does your business operate in the EU or support EU-based services? Then, regulators will look for proof that your systems can withstand attacks.
What does the NIS2 expect from your business?
Stripped down to basics, NIS2 wants you to prove that you can respond to incidents and stay operational when breaches do occur. You must:
- understand where your risks are across vendors and access points
- detect and report incidents within strict timelines
- involve leadership in cybersecurity decisions
- keep services running even when systems are under attack
What does it take to secure your systems?
- Map your infrastructure:
- What systems are critical to operations
- Where sensitive data is located
- Who has access and how they authenticate
- Which third parties connect to your environment
- Once you see the full picture, tighten your control over who and what can access your systems.
- Lock down access using role-based permissions
- Enforce multi-factor authentication
- Remove unused accounts and reduce unnecessary privileges
- Then focus on exposure.
- Run regular vulnerability scans and penetration tests
- Patch immediately
- Make system activity visible.
Actions usually move across systems: a login could trigger an API call, then hit a database, which updates records or calls another service. You don’t want each part to log activity separately. A properly configured SIEM cybersecurity setup can pull those events into one view and line them up in sequence, so you can follow what happened as it’s happening.
How do you keep operations running during an attack?
- Define:
- Which services must stay online
- What fallback processes exist
- How quickly systems can be restored
A second SIEM cybersecurity layer can help you correlate incidents across you infrastructure.
- Build redundancy into critical systems.
Separate environments so one breach doesn’t spread everywhere. Back up your data frequently and test whether you can actually recover it.
Cyberanalytics works directly with businesses that need to comply with NIS2. If you want to track how data moves across your systems and where it can be exposed — and fix it before regulators or attackers find it — call us at +48 886 282 803.
