Protocol analyzers allow administrators to peer into the actual packets traveling on a network. This is very useful when trying to troubleshoot network issues or investigate security incidents. Learn how cybersecurity professionals use protocol analyzers, such as Wireshark, to examine network activity.
- [Instructor] Protocol analyzers are an important tool…available to both network and security professionals.…Protocol analyzers allow administrators to peer…into the actual packets travelling on a network…and inspect them in deep detail.…This is very useful when trying to troubleshoot…network issues or investigate security incidents.…Protocol analyzers must be used carefully, however,…because they can also jeopardize the confidentiality of…sensitive information when they're used in the wrong hands.…
Let's take a look at a protocol analyzer in use.…We're going to use Wireshark, the most common…and free protocol analyzer.…Right here I'm running Wireshark on a server…that runs on a cloud.…And I have an RDP session open to the system…from my laptop that's running over port 3389.…I'm going to go here and just click start…to initiate the packet capture.…And immediately the screen begins filling up…with lines of communication.…Each one of these lines on the screen,…and you can see it's started scrolling already,…there's so many of these.…
