Prevention Strategies

1. Robust Backup and Recovery Systems

3-2-1-1-0 Backup Rule

  • 3 copies of important data
  • 2 different storage media types
  • 1 offsite backup location
  • 1 offline or immutable backup
  • 0 errors in backup verification

Backup Infrastructure Best Practices

  • Regular automated backup scheduling
  • Encryption of backup data at rest and in transit
  • Air-gapped or immutable backup storage
  • Regular recovery testing and validation
  • Comprehensive backup monitoring and alerting

Recovery Time and Point Objectives

  • Define Recovery Time Objectives (RTO) for critical systems
  • Establish Recovery Point Objectives (RPO) for data tolerance
  • Document detailed recovery procedures
  • Test recovery processes regularly
  • Train staff on recovery protocols

2. Network Segmentation and Access Controls

Zero Trust Architecture Implementation

  • Verify all users and devices before granting access
  • Implement least privilege access principles
  • Continuous monitoring and validation
  • Micro-segmentation of network resources
  • Dynamic access controls based on risk assessment

Network Security Controls

  • Next-generation firewalls with deep packet inspection
  • Intrusion detection and prevention systems (IDS/IPS)
  • Network access control (NAC) solutions
  • VPN security hardening and monitoring
  • Regular network vulnerability assessments

3. Endpoint Protection and Hardening

Advanced Endpoint Security

  • Next-generation antivirus with behavioral analysis
  • Endpoint detection and response (EDR) solutions
  • Application whitelisting and control
  • Device encryption and secure boot processes
  • Regular security patching and updates

System Hardening Measures

  • Disable unnecessary services and protocols
  • Implement application control policies
  • Configure secure system settings
  • Regular security configuration reviews
  • Automated compliance monitoring

4. Email and Web Security

Email Security Solutions

  • Advanced threat protection (ATP) for email
  • Sender Policy Framework (SPF) implementation
  • DomainKeys Identified Mail (DKIM) validation
  • Domain-based Message Authentication (DMARC) policies
  • User education on phishing recognition

Web Security Controls

  • Secure web gateways (SWG) deployment
  • DNS filtering and threat intelligence
  • Web application firewalls (WAF)
  • Content filtering and categorization
  • Regular web application security testing
