What is a firewall?
- A firewall is a network security system that establishes a barrier between a trusted, secure internal network and another network that may not be secure.
- Additionally, a firewall can help prevent hackers or malicious software from gaining access to your computer through a network or the Internet. A firewall can also help stop your computer from sending malicious software to other computers.
