If you use encryption types, such as WEP, WPA, WPA2, IPsec, or SSL / TLS, you can configure Wireshark with keys so that it can decrypt and display real data if needed.

5. TeamViewer: Remote Desktop

Windows, Mac OS X, and Linux all have remote desktop solutions, though they are all incompatible. Using a protocol and application will make it a lot simpler to work with multiple platforms. However, operating system developers have not yet made it easy to use their solutions.
