Get Security AuditRansomware Attacks Are Preventable
90% of ransomware attacks exploit known vulnerabilities that could have been patched. Follow our prevention guide to significantly reduce your risk.
Essential Ransomware Prevention Measures
Implement these critical security measures to protect your systems from ransomware attacks:
Patch Management
Keep all software and operating systems updated with the latest security patches to eliminate vulnerabilities.
User Training
Educate employees on phishing emails, suspicious links, and social engineering tactics used by attackers.
3-2-1 Backup Rule
Maintain 3 copies of data, on 2 different media, with 1 copy offline/offsite to ensure recoverability.
Access Controls
Implement least privilege access and multi-factor authentication to limit ransomware spread.
Email Filtering
Use advanced email security to block malicious attachments and phishing attempts before they reach users.
Endpoint Protection
Deploy next-gen antivirus with ransomware-specific detection capabilities on all devices.
Ransomware Prevention Implementation Guide
Step-by-step instructions to build your ransomware defense strategy:
Conduct a Security Assessment
Identify vulnerabilities in your current infrastructure:
- Perform vulnerability scanning
- Review current backup procedures
- Evaluate endpoint protection
- Analyze user access privileges
- Test incident response plans
Note: We offer free initial security assessments to identify your most critical risks.
Implement Backup Best Practices
Establish a robust backup strategy that protects against ransomware:
- Schedule automated daily backups
- Maintain offline/air-gapped backups
- Test backup restoration monthly
- Encrypt backup data
- Monitor backup integrity
Warning: Many ransomware variants now specifically target and encrypt backup files.
Harden Your Network Defenses
Implement network-level protections against ransomware:
| Defense | Implementation | Effectiveness |
|---|---|---|
| Email Filtering | Advanced threat protection for attachments/links | Blocks 95% of initial infection vectors |
| Network Segmentation | Isolate critical systems from general network | Limits lateral movement of ransomware |
| Application Whitelisting | Only allow approved executables to run | Prevents 99% of ransomware execution |
| RDP Security | VPN + MFA for remote access, disable direct RDP | Blocks common brute force attacks |
Develop an Incident Response Plan
Prepare for potential ransomware incidents with a clear response plan:
- Detection: Implement monitoring for early warning signs
- Containment: Immediate isolation procedures for infected systems
- Communication: Designate response team and notification procedures
- Recovery: Documented restoration processes from clean backups
- Review: Post-incident analysis to improve defenses
Tip: Regularly test your incident response plan with simulated ransomware scenarios.
Ransomware Attack Vectors and Prevention
Understand how ransomware spreads and how to protect against each method:
| Attack Vector | Percentage of Attacks | Prevention Measures |
|---|---|---|
| Phishing Emails | 54% | Advanced email filtering, user training, disable macros |
| RDP Exploitation | 27% | VPN with MFA, RDP gateways, network-level authentication |
| Software Vulnerabilities | 13% | Patch management, vulnerability scanning, application control |
| Malicious Websites | 4% | Web filtering, browser hardening, ad blockers |
| USB/Removable Media | 2% | Device control policies, disable autorun, regular scanning |
