There are various ways to avoid it and nowadays since ransom attacks have become common , so I’ll list a few methods -:

• Regular Backups:
  • Frequency: Perform regular backups of critical data.
  • Storage: Store backups offline and offsite to prevent ransomware from accessing them.
  • Testing: Regularly test backups to ensure they can be restored successfully.
• Employee Training:
  • Awareness Programs: Conduct regular training on recognizing phishing attempts and other social engineering tactics.
  • Phishing Simulations: Run simulated phishing campaigns to test and improve employee vigilance.
• Patch Management:
  • Regular Updates: Keep all software, including operating systems and applications, up to date with the latest security patches.
  • Vulnerability Management: Use tools to identify and address vulnerabilities in your systems.
• Endpoint Protection:
  • Antivirus/Antimalware: Use reputable antivirus and antimalware software with real-time protection.
  • Endpoint Detection and Response (EDR): Implement EDR solutions to monitor and respond to threats on endpoints.
• Network Segmentation:
  • Isolate Critical Systems: Segregate critical systems and sensitive data from the rest of the network to limit the spread of ransomware.
  • Access Controls: Implement strict access controls and least privilege principles.
• Email Filtering:
  • Spam Filters: Use robust spam filters to reduce the likelihood of malicious emails reaching users.
  • Attachment Scanning: Scan email attachments for potential threats before delivery.
• Multi-Factor Authentication (MFA):
  • User Accounts: Enforce MFA for all user accounts, especially those with administrative privileges.
  • Remote Access: Require MFA for remote access to your network

Hope it helps!
