A firewall is a system that enforces access control between two or above networks. Only authorized traffic between the organization and the outside, as formal security policy specifies, is allowed to pass through the firewall.

Organizations connected to their customers and business partners via the Internet are particularly exposed. Without adequate protection, organization open their doors to computer hackers, thieves, vandals, and industrial spies both internally and from around the
