The advantage of this solution is that while dumpcap is run as root the vast majority of Wireshark's code is run as a normal user (where it can do much less damage). This can be achieved by installing dumpcap setuid root. Wireshark has implemented Privilege Separation which means that the Wireshark GUI (or the tshark CLI) can run as a normal user while the dumpcap capture utility runs as root.

The Security page provides explanations why this is a good idea. To be secure (at least in a way), it is recommended that even an administrator should always run in an account with (limited) user privileges, and only start processes that really need the administrator privileges. The way this is done differs from operating system to operating system. We need to run Wireshark or TShark on an account with sufficient privileges to capture, or need to give the account on which we're running Wireshark or TShark sufficient privileges to capture. Install these dependencies by running the following commands one by one.Capture privileges - How to enable Wireshark without running as root We have shortlisted the details of packages considered as dependencies which should be installed before going to install new Wireshark.
