Server management is a critical element in the field of information technology and is essential for maintaining the security and efficiency of digital systems. The National Cyber and Information Security Agency (NUKIB) provides several recommendations for server administrators to protect against cyber threats. These recommendations include:

  1. Updates and Patches: Regular updates of software and the server's operating system are essential. Administrators should regularly check for and install security patches and updates to prevent exploitation of vulnerabilities.

  2. Data Backup: Important data should be regularly backed up to secure and different locations. In case of an attack or system failure, this enables quick data recovery without significant losses.

  3. Security Tools and Firewall: Using security tools, such as antivirus programs and a firewall, helps protect the server from unauthorized access and malware. The firewall should be properly configured to block dangerous traffic.

  4. Encryption and Authentication: The use of strong encryption for sensitive data and secure user authentication methods is key. Two-factor authentication provides an additional layer of security.

  5. Physical Security of the Server: The physical security of servers should not be underestimated. They should be located in secure areas with controlled access.

  6. Monitoring and Audit: Regular monitoring and auditing of servers can detect unusual activities or potential security issues. Automated tools for monitoring can be significantly helpful.

  7. Employee Awareness and Training: Employees should be regularly trained in cyber security. Being informed about current threats and proper practices can significantly reduce the risk of an attack.

  8. Incident Response Plan: It is important to have a prepared plan for cyber incidents, including procedures for addressing and reporting these incidents.

  9. Regular Security Assessments: Regular security audits and vulnerability testing help identify and eliminate weak points in security settings.

  10. Access and Permission Restrictions: It is important to limit access to servers to only necessary users and applications and to properly set permissions.

By following these NUKIB recommendations, server administrators can significantly contribute to the security and stability of their IT systems. Cybersecurity is an ongoing process, and it is important to always be one step ahead of potential threats.
