Close every port you don't use.

Control the ports

Every computer has 65,536 ports each for TCP and UDP. Port Security lets you decide which ones stay open and shuts the rest.

• Block by port number, range, or jam everything at once

  Close a single port like 23, or a whole range, in one rule. Works for TCP and UDP.

• Sets the bound

  The way you wanted to do it

• Profiles for different machines

  A laptop, a kiosk, and a server shouldn't share the same open ports. Build a profile for each and apply it where it belongs.

• A clear record of what's blocked

  See which ports are closed or open on each computer./p>

• Military Grade Protection

  Protection how the military would have done it. (Hint, hint)

• Metasploit Blocking

  Blocks most Metasploitable attacks against Windows PCs

Questions

Straight answers about what the product does.

What is a network port?

A port is a numbered doorway a computer uses to send and receive network traffic. For example, web traffic commonly uses 80 and 443, and remote desktop commonly uses 3389. An open port with nothing needing it is an unnecessary way in.

How is this different from a firewall?

A firewall is the usual way a computer's ports get filtered, and Port Security works at that same level. Its job is to make closing and tracking ports simple to set up and easy to see across your machines.

Will blocking a port break something?

It can if a program on the machine needs that port. Block only ports you know are unused, and start with a small set. You can allow a port again at any time.

Does this replace other security measures?

No. Closing ports reduces what's exposed, which is one layer. Keep updating software, using strong credentials, and following your other security practices.

Do I need administrator access?

Changing port rules on a computer generally requires administrator rights, so the person setting it up will need them.
