Ransomware Prevention
Comprehensive protection against ransomware attacks
1. Ransomware – Threat #1 for Businesses Today
In 2024, over 65% of severe data loss incidents in Vietnam originated from ransomware (according to VNCERT).
Ransomware is a type of malware that: Infiltrates the system (usually via email, USB, fake websites), Encrypts all data, systems, backup files, Demands ransom from the business (usually in Bitcoin).
Without preventive measures from the start, recovery costs can be 5–10 times the initial security investment.
2. Businesses are vulnerable to ransomware when…
| Common Situation | Risk |
|---|---|
| No regular data backups | Cannot recover data if encrypted |
| Staff lacks security awareness | Easily click fake links, download dangerous files |
| Computers lack endpoint protection | Hackers easily gain access |
| Internal network not segmented | Malware spreads throughout the system |
| No log monitoring, no alerts | Attack undetected until it's too late |
3. Multi-Layered Defense System
We build a multi-layered defense system based on the model:
Layer 1: Early Intrusion Prevention (Perimeter)
- UTM Firewall with IDS/IPS
- Web filtering – block malicious websites
- Email gateway protection before mail reaches staff
Layer 2: Endpoint Protection
- AI-integrated EDR/Antivirus solution
- USB control – prevent spread from peripherals
- Behavior monitoring – alert on abnormal encryption
Layer 3: Backup & Recovery
- 3-2-1 backup rule
- Periodic data snapshots
- Disaster Recovery Testing
4. Integration with International Security Standards
The solution is designed to meet or support the implementation of standards:
- ISO 27001: A.5.15, A.5.18, A.8.13, A.8.16
- NIST CSF: Identify – Protect – Detect – Respond – Recover
- ISO 22301: Business Continuity Management (BCP/DRP)
5. Case study: Manufacturing company fully encrypted due to public RDP
Situation: IT opened port 3389 (Remote Desktop) for convenient remote access. No monitoring, no Windows updates.
Hackers scanned the port, exploited it, installed ransomware → Affected entire accounting system, data servers, product designs → Took 3 weeks to recover, hundreds of millions in damages.
Cyber IT Security proposed solution:
- Close RDP port, use VPN with 2FA
- Separate LAN & servers
- Regularly backup important data
- Monitor system logs
