Ransomware is no longer a threat reserved for large corporations; it targets small businesses with high success rates. As an IT expert, I constantly stress that proactive defense is cheaper than paying a ransom.

1. Implement the Principle of Least Privilege (PoLP)

Do your employees truly need administrative rights to do their job? For most, the answer is no. PoLP dictates that users should only have the minimum permissions necessary. If a standard user account is compromised, the ransomware's lateral movement within the network is severely restricted, limiting the potential damage.

2. Enforce Strict 3-2-1 Backups

This is the gold standard for data recovery. The rule states you should have:

  • 3 copies of your data (the primary data and two backups).
  • 2 different media types (e.g., local server and external HDD).
  • 1 copy stored off-site (cloud storage or physical media off-premises).

The off-site, immutable (unchangeable) cloud backup is the critical lifeline when local systems are encrypted.

3. Phishing Simulation and Training

Over 90% of ransomware attacks start with a phishing email. Technology can only do so much; your employees are your first and last line of defense. Regular, unannounced phishing simulations help identify weak points, and mandatory training reinforces best practices.

4. Keep Systems Patched and Updated

Unpatched software vulnerabilities are a favorite target. Utilize Managed Service Provider (MSP) tools to ensure all operating systems and third-party applications (browsers, plugins, Java, etc.) are kept current. Automated patching minimizes the window of opportunity for attackers.

5. Advanced Endpoint Detection and Response (EDR)

Traditional antivirus is no longer enough. EDR solutions monitor your endpoints (desktops, laptops, servers) in real-time for suspicious behavior (like mass file encryption) and can automatically isolate the infected device before the malware spreads across the network.
