Enterprises usually resort to blocking websites and applications for data security purposes. For instance, they ban the use of social media sites like Facebook and file sharing apps like Dropbox to protect sensitive data from being shared intentionally by the employees. However, blocking is not the solution.
A sniffer is a software or hardware tool that allows users to monitor internet traffic in real-time. It has various benefits such as monitoring network traffic, identifying invalid nodes, and debugging application traffic. But sniffers have downsides as well. Cybercriminals use sniffers to tap into a network and capture confidential information.
