wireshark is a powerful open - source network analysis tool. it allows network administrators, security experts, and developers to capture and analyze network traffic in real - time.
by using wireshark, one can inspect packets at a granular level. it reveals details such as source and destination ip addresses, protocols in use, and the content of data within packets. this helps in troubleshooting network issues, like identifying bottlenecks or connection failures. in security, it can detect abnormal traffic patterns that might indicate a cyber - attack, such as unauthorized access attempts or data exfiltration. overall, wireshark is an essential asset for understanding and optimizing network performance and security.
