What is Network Sniffing?

Network Sniffing involves hardware or software that monitors and/or analyzes network traffic. Network sniffing can be done ethically – such as admins monitoring their own network’s status – or maliciously – as these tools in the hands of a hacker can be used to not only monitor private networks, but also intercept, and steal private information traveling over it such as user logins, emails, and proprietary data.

How to Recognize This Threat: An unauthorized sniffer is generally quite difficult to spot unless other sniffers are running to detect them.

How to Prevent This Threat: Secure your network against outside threats such as network sniffers with a firewall along with a security services subscription. Get a firewall Free with a 3-year subscription through SonicWall or Sophos.
