How to track and restrict internet usage in your network?

Internet can be a benefit to business when used properly, but internet is often abused by employees and poses significant liability and security risks:

  • 1. Internet downloading and malicious websites are harmful to your network.
  • 2. Online messengers, social networks websites are killing your productivity.
  • 3. P2P programs and IPTV applications can easily consume most of your bandwidth.
  • 4. Sharing of copyrighted popular music and movies is illegal in most jurisdictions.

Therefore, it is necessary for business administrators to track employees internet usage and restrict internet usage in company networks.

Below I list several aspects to track and filter internet activity on company networks.

1. Keep a record of internet activities.

To track internet usage, you can setup a mirroring port in your switch, and connect an internet monitoring product to this mirroring port to archive all internet activities.

  • 1. Only work-related websites are allowed during work time.
  • 2. Destructive websites like violence, adult, shall be blocked always.
