When working with packet captures, trace files can contain sensitive information. Lisa Bock demonstrates how you can see the contents of a trace file and stresses the importance of sanitizing packet captures before sharing or posting on the web.
- [Instructor] Aside from Wireshark,…there are many other packet analysis tools and techniques…that are used in many other places such as businesses.…They monitor what we view…so they can present directed content and advertising.…And government, they use packet sniffing…to monitor for threats.…And hackers monitor and look for sensitive information…such as username and password.…
We know this so we take steps to encrypt our data…and conceal it either while it's in motion…or while it's in rest.…But what about our packet captures?…I have a little example to show you,…but if you want to follow along,…you can get this off of the website…the SampleCaptures page in the wiki on Wireshark…and this is the one I'm going to select…and I have another one that's been sanitized…and you'll need to unpack it.…
Now the first one I'm going to open has been sanitized.…Now I'll right click…and we'll follow the stream…and here you can see that the domain is concealed.…Down below, the email address is concealed.…So that's one step you can take…
