Chapter 6 Server Maintenance A network server refers to a dedicated computer or software application that provides network services to other computers, known as clients, within a network. These servers play a crucial role in facilitating communication and resource sharing among devices in a network.  Network server maintenance is crucial for ensuring the smooth and secure operation of a networked infrastructure. Regular and proactive maintenance helps prevent issues, optimize performance, and enhance the overall reliability of the network.  IMPORTANCE OF NETWORK SERVER MAINTENANCE Prevent Downtime Performance Optimization Security Updates Data Integrity and Backup Resource Management Software and Application Updates Hardware Health Monitoring License Compliance  IN SERVER MAINTENANCE Backup Regularly Test Backups Implement Update Software Redundancy and Security Patches and Failover Regularly Check Monitor Server Health for Hardware Issues Document Changes Perform Regular Security Audits  IN SERVER MAINTENANCE Neglect Regular Maintenance Skip Monitoring Make Changes Assume Backups Are Without Testing Always Successful Overlook Security Delay Security Patching Best Practices Forget Documentation Security Protection Measures  Keep Software Updated Use Strong Authentication Firewall Configuration Encrypt Data in Transit and at Rest  Regular Backups Monitoring and Logging Access Control Intrusion Detection and Prevention Systems (IDPS) Back-up Plan and Procedures 1.
