In computing, a firewall can be software or hardware-based network security system that may control the incoming and outgoing network traffic by analyzing the data packets and determining whether they should be allowed through or not, based on a rule set. A firewall may establish a barrier between a trusted, secure internal network and another network that can be not assumed to be secure and trusted.
Many personal computer operating systems may include software-based firewalls to protect against threats from the public Internet. Many routers that can pass data between networks may contain firewall components and, conversely, many firewalls can perform basic routing functions.
