Firewalls are computer programs that protect computers from unauthorized access. They do this by blocking traffic from certain sources.
There are many different types of firewalls, but all of them have a few common features.
First, all firewalls have a rule-based system. This means that they are designed to allow certain types of traffic through, while blocking other types.
Second, all firewalls have a filtering engine. This is a program that looks at the traffic that is being sent through the firewall and decides whether or not it is allowed.
Third, all firewalls have a monitoring feature. This allows the administrator to track the traffic that is passing through the firewall.
Fourth, all firewalls have a security feature. This allows the administrator to password protect the firewall and protect it from unauthorized access.
Finally, all firewalls have a configuration management system. This allows the administrator to manage the firewall’s settings and rules.
