Crypto And Ransomware – Understanding and Defending Against Ransomware Attacks

  1. How to Protect Your Organization

Here are the essential steps, explained in simple and accessible terms:

2. Back up your data regularly

Keep copies of your important data in another location (USB drive, disconnected external disk, secure cloud). Regularly test that your backups can be restored correctly.

3. Keep all devices up to date

Always install security updates. They fix vulnerabilities that attackers often use to break into systems.

4. Use a reliable antivirus and security tools

These tools help detect viruses, suspicious behavior, and prevent attacks from spreading.

5. Protect your Internet access

A firewall filters incoming and outgoing connections and blocks unauthorized access.
Smaller organizations can already activate basic security features directly on their Internet router.

6. Secure remote access

If someone connects from outside (teleworking, maintenance), use a VPN and enable two-factor authentication.

7. Give users only the access they need

Each employee should have only the permissions necessary for their tasks — nothing more.

8. Use strong passwords

Choose long, complex, and unique passwords for each service. Change default passwords and enable two-factor authentication whenever possible.

9. Never install pirated software

Even if it seems convenient or free, pirated programs often contain malware.

10. Train and raise staff awareness

Regularly remind employees how to recognize suspicious emails, dangerous links, and how to react in case of a cybersecurity issue.

11. For more advanced organizations: Monitor system activity

Check system logs (firewall logs, server logs, etc.) to detect unusual or suspicious behavior.

12. Advanced: Strengthen Internet connection security

Using a proxy or an application firewall (WAF) can provide an additional level of protection.

13. Advanced: Segment your network

Separating your internal network into different zones helps prevent attackers from spreading throughout the entire system if one zone is compromised.
