Ransomware has become the defining cybercrime of our era. Attackers encrypt your data, shut down your operations, and demand payment — often targeting backups to leave you with no option but to pay.
The good news: most ransomware attacks succeed because of preventable gaps, not sophisticated exploits. Here are 10 controls that eliminate most of the risk.
1. Enforce Multi-Factor Authentication Everywhere
Over 80% of ransomware intrusions begin with stolen credentials. MFA breaks this attack chain. Deploy it on email, VPN, remote desktop, and every cloud service — no exceptions.
2. Patch Systems Within 14 Days of Release
Ransomware groups weaponise public vulnerabilities within days. A disciplined patch cycle (critical patches within 14 days, others within 30) closes the window attackers rely on.
3. Implement Email Filtering and Anti-Phishing Controls
Phishing remains the most common initial access vector. Deploy DMARC, DKIM, and SPF on your domain. Use an email security gateway that sandboxes attachments before delivery.
4. Deploy Endpoint Detection and Response (EDR)
Traditional antivirus misses modern ransomware. EDR tools monitor process behaviour and can terminate ransomware execution before encryption begins — even on day-zero variants.
5. Segment Your Network
Ransomware spreads by moving laterally through flat networks. Micro-segmentation and VLAN isolation mean a compromised workstation cannot reach file servers, backup systems, or OT networks.
6. Restrict Remote Desktop Protocol (RDP)
RDP exposed to the internet is one of the most exploited entry points. Disable it entirely if not needed. If required, put it behind a VPN and enforce MFA.
7. Maintain Offline, Immutable Backups
Ransomware increasingly targets backup systems. Follow the 3-2-1 rule: three copies, two different media types, one offsite/offline. Test restores quarterly — a backup you haven’t tested is not a backup.
8. Apply Least Privilege Across All Accounts
Limit what each user and service account can access. A ransomware payload running as a standard user causes far less damage than one running as a domain admin.
9. Run a Tabletop Exercise
Know what you’ll do before you’re forced to. A tabletop exercise walks your team through a simulated ransomware incident — so decision-making is fast and coordinated when it matters.
10. Conduct Regular VAPT Testing
Vulnerability assessments and penetration tests show you exactly which gaps ransomware actors would exploit — before they do. Fix what you find.
Cyberto Solutions offers managed endpoint security, network segmentation assessments, and full VAPT engagements to help your organisation close these gaps systematically.
