Anyone who uses a tool like Wireshark without first obtaining the necessary permissions may quickly find themselves in hot water legally. However, as a security professional, there are two important reasons to sniff network traffic. First, peering into the details of packets can prove invaluable when dissecting a network attack and designing countermeasures. For example, if a denial of service occurs, Wireshark can be used to identify the specific type of attack. The tool can then craft upstream firewall rules that block the unwanted traffic. The second major use of Wireshark is to troubleshoot security devices. ![]() Specifically, I regularly use it to troubleshoot firewall rules.
