BRIEF ABOUT TOPICS
A firewall is a network security system, either hardware- or software-based, that controls incoming and outgoing network traffic based on a set of rules. Acting as a barrier between a trusted network and other untrusted networks, such as the Internet or less-trusted networks. A firewall controls access to the resources of a network through a positive control model. This means that the only traffic allowed onto the network defined in the firewall policy is, all other traffic is denied. Thus it protects (an internal network or system) from unauthorized access.

3.Understand the requirements, characteristics and limitations of firewall in networks.
4.Understand how the network traffic passes inside and outside (to/from the internal corporate network and to/from outer side network) from the system through firewall.
