1. Data Backup & Recovery Policy
- Implement automatic, encrypted, and offsite backups of critical data.
- Use the 3-2-1 backup rule (3 copies, 2 different media, 1 offsite).
- Regularly test backup restoration to ensure data can be recovered.
- Store backups in a way that prevents ransomware from accessing them (e.g., air-gapped or immutable storage).
2. Endpoint Security & Antivirus Policy
- Deploy next-gen antivirus (NGAV) and endpoint detection & response (EDR) tools.
- Require real-time scanning of files and attachments for malware.
- Block unauthorized software installations using application whitelisting.
- Automatically isolate infected devices to prevent lateral movement.
3. Email & Phishing Protection Policy
- Implement email filtering and scanning to block phishing attempts.
- Use DMARC, SPF, and DKIM to prevent email spoofing.
- Train employees to recognize malicious email attachments, links, and social engineering attacks.
- Prohibit enabling macros in email attachments by default.
4. Patch Management & Vulnerability Policy
- Enforce regular software updates and patching of operating systems, applications, and firmware.
- Use automated vulnerability scanning to detect security weaknesses.
- Establish patching SLAs (e.g., high-risk vulnerabilities patched within 48 hours).
- Require legacy system replacement if security updates are no longer available.
5. Network Segmentation & Access Control Policy
- Implement Zero Trust Architecture (ZTA) to limit access based on identity verification.
- Use firewalls, network segmentation, and VPN restrictions to control traffic.
- Restrict admin privileges to essential personnel only.
- Require Multi-Factor Authentication (MFA) for remote access, VPNs, and privileged accounts.
6. Incident Response & Ransomware Playbook Policy
- Develop a ransomware-specific response plan with clear roles and responsibilities.
- Establish a crisis communication plan to notify stakeholders without worsening the situation.
- Work with law enforcement & cybersecurity firms in case of extortion.
- Prohibit employees from paying ransoms without executive approval.
7. Secure Remote Work & Bring Your Own Device (BYOD) Policy
- Enforce VPN usage with encryption when accessing company resources remotely.
- Mandate corporate security software on personal devices used for work.
- Restrict the use of personal cloud storage for company files.
- Enable remote wipe capabilities for lost or stolen devices.
8. Least Privilege & Admin Account Security Policy
- Follow the Principle of Least Privilege (PoLP)—limit admin access to only what is necessary.
- Require separate accounts for administrative tasks (no dual-purpose accounts).
- Monitor and log privileged account activity for unusual behavior.
- Implement Just-in-Time (JIT) access to reduce persistent admin privileges.
9. Threat Intelligence & Security Monitoring Policy
- Deploy Security Information & Event Management (SIEM) systems for real-time threat monitoring.
- Subscribe to cyber threat intelligence feeds to stay updated on new ransomware variants.
- Require 24/7 security monitoring via internal teams or Managed Security Services Providers (MSSPs).
- Conduct regular penetration testing to identify security gaps.
10. Employee Cybersecurity Awareness & Training Policy
- Conduct mandatory ransomware awareness training for all employees.
- Run regular phishing and social engineering simulations.
- Encourage a culture of reporting suspicious emails and activities immediately.
- Implement a zero-tolerance policy for security negligence.
