A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It typically establishes a barrier between a trusted internal network and untrusted external network, such as the Internet.
As the nature of network threats and networks themselves change, the firewall still plays an important role. Enterprises looking to purchase a firewall should be aware of their needs and choose accordingly.
Many organizations may have purchased a firewall but may not have configured it correctly or are not using it to its full capability. Zunesis has created a Firewall Assessment to help your organization with your network security firewall needs.
