Description

For most organizations the first line of defense is the firewall system. This term can actually represent different components and this course explores this interesting concept. The term firewall is a metaphor for protecting separate zones or domains. In a network, a firewall is intended to control what passes from one security zone to another. If a system is compromised in one zone, firewalls help to contain the attack to within that zone. Also, within a network, firewalls also have the function of preventing the undesirable access in the first place. This course explores the fundamentals of firewall technologies.
