How to Encrypt Data in Motion
CBT Nuggets trainer Knox Hutchinson dives deep into keeping network traffic that’s passing from one device to another (‘in motion’) safe. Data in motion is vulnerable – but it’s possible to secure it. Encrypting data in motion takes planning, expertise and knowledge of certain protocols that make it all possible.
Data in motion is one of the easiest things to hack, which is why it’s important to protect it first. A favorite tactic of hackers is to use a tool like a protocol analyzer to grab traffic as it flows across a wire. Protocol analyzers allow a hacker to intercept a copy of all the packets that flow across the network and then easily reconstruct the traffic.
If that traffic is sent in the clear, information like user names and passwords are completely exposed. Whether it’s by address bar, GUI or command line interface – even if you enter your user name and password directly or via Telnet – if you’re using an unencrypted protocol, a bad actor can intercept all that information.
