Our Recommendations

We make the following recommendations to strengthen your cybersecurity and reduce the risk of ransomware infection:

1.   Require multi-factor authentication (MFA) for all remote access (VPN, etc.), as well as for email. No exceptions should be made.

2.   Implement a defense-in-depth strategy for your network: use EDR on every endpoint (whenever possible), deploy IDS/IPS/NDR to protect the network perimeter, collect and analyze access control logs, etc.

3.   Always back up this data. Follow the 3-2-1 rule by keeping multiple copies of the data: three copies in total, stored on two different types of media, with at least one copy kept off-site.

4.   Ensure that your operating systems and applications are regularly updated to reduce vulnerabilities often exploited by ransomware and other malware.

5.   Raise awareness among your users about cyber risks.

6.   Monitor your network security 24/7. Threat actors don't take weekends or vacations.
