Firewalls are used to control access to a network by allowing only authorized traffic to pass through. They can be hardware devices or software programs that analyze incoming and outgoing data packets based on a set of predefined rules. Firewalls can be used to block specific types of traffic or limit access to certain websites or applications. Encryption, VPNs, anonymizing tools, and filtering can also be used for network security, but they do not specifically control access to a network like firewalls do.
