Ransomware spiked in 2024, with attacks like LockBit 3.0 hitting small and mid-sized businesses hard, costing millions in downtime and recovery. Sysadmins, securing your network is non-negotiable in this threat landscape.
The Issue: Phishing emails and unpatched vulnerabilities (like those in outdated VPNs or Windows Server 2016) let ransomware slip through, encrypting critical data and halting operations.
Quick Fix:
Patch Religiously: Use tools like SCCM or Intune to auto-deploy updates for OS and apps. Prioritize CVEs with high severity (e.g., CVE-2024-29847).
Segment Networks: Isolate critical systems with VLANs to limit ransomware spread. Use pfSense or Cisco for easy setup.
Backup Smart: Follow the 3-2-1 rule (3 copies, 2 local, 1 offsite). Test restores monthly with Veeam or rsync.
Tip: Deploy an EDR solution like CrowdStrike Falcon for real-time threat detection. It’s a game-changer for catching ransomware early.
