Firewalls as first line of defense
The main function of a firewall is to act as the first line
of defense into your network, protecting it from external
attacks. You can also use a firewall to open up ports for
specific incoming and/or outgoing traffic. Firewalls also
have logging facilities that will inform you about any
failed attacks on your network.
Please check the link below of my website where u can find
more about firewalls and other it solutions available.
