Step-by-step explanation:
Analyzing Network Performance, Efficiency, and Security
An IT professional can analyze the performance, efficiency, and security of the network by using network monitoring and diagnostic software. One specific software suite that can be used is Wireshark.
Performance: Wireshark can capture and analyze network traffic, helping IT professionals identify any bottlenecks or performance issues. They can examine packet loss, latency, and bandwidth utilization to optimize network performance.
Efficiency: By monitoring network traffic, IT professionals can identify ineffective protocols or unnecessary network traffic that may be impacting efficiency. They can analyze the data provided by Wireshark to make informed decisions about network design and configuration.
Security: Wireshark can detect and analyze network vulnerabilities, malicious activity, and unauthorized access. IT professionals can use it to monitor traffic for signs of intrusions, identify suspicious patterns, and strengthen network security measures.
