Network monitoring is primarily used to detect and resolve network issues, ensuring the smooth operation of the network.

Ping, Traceroute, and SNMP are all commonly used network monitoring tools.

SNMP stands for Simple Network Management Protocol.

A Network Operations Center (NOC) is responsible for monitoring and managing network devices, analyzing network traffic, and responding to network incidents.

Latency, throughput, and packet loss are all common metrics used for monitoring network performance.

Active monitoring involves sending probes to network devices, while passive monitoring involves listening to network traffic. Active monitoring is used for real-time monitoring, while passive monitoring is used for historical analysis. Active monitoring is more resource-intensive than passive monitoring.

Network traffic analysis is used to identify network security threats, optimize network performance, and troubleshoot network issues.

Malware, phishing, and DDoS attacks are all common types of network security threats.

A firewall's primary role is to block unauthorized access to a network.

Network intrusion detection systems (NIDS) are used to detect and alert on suspicious network activity.

Network monitoring software, configuration management tools, and network automation tools are all common network management tools.

Network configuration management is used to ensure that network devices are configured correctly, track changes to network configurations, and automate network configuration tasks.

Network automation can provide reduced operational costs, improved network performance, and increased network security.

AI can be used to automate network monitoring tasks, analyze network data and identify trends, and detect and respond to network anomalies.

The increasing complexity of networks, the growing volume of network data, and the need for real-time monitoring are all challenges associated with network monitoring.
