Network management is the process of administering, operating, and securing computer networks to ensure optimal performance and availability. It involves monitoring network devices, analyzing traffic patterns, and implementing security policies to prevent unauthorized access and data breaches. Effective network management is crucial for maintaining business continuity, supporting user productivity, and safeguarding sensitive information. For instance, a network administrator might use network management tools to detect and isolate a compromised device exhibiting unusual traffic patterns. This differs from network monitoring, which focuses solely on observing network status and performance, whereas management encompasses proactive control and remediation. Network management concepts are frequently assessed on certifications like CompTIA Security+, CISSP, and CCSP.
