Ransomware
Ransomware resilience programme: the 4 pillars (NCSC)
The NCSC stresses no sector is immune; resilience beats hoping not to be hit.
Four pillars: (1) exposure reduction (MFA, segmentation, hardened backups), (2) early detection (logs, MSSP/SOC), (3) response (playbooks, crisis cell, comms), (4) recovery (tested backups, DR). MiliSec turns these into a 90-day plan with owners and evidence.
The MiliSec method
What we run for our Virtual CISO clients:
- Test immutable, offline backups quarterly.
- Segment OT/IT and critical VLANs.
- Run a ransomware tabletop with the crisis cell.
Going further
Ransomware is no longer a bug, it is organised crime. Groups encrypt, exfiltrate then negotiate.
Resilience is built before the crisis: tested immutable backups, segmentation, and a recovery plan rehearsed under real conditions.
