This session will be started with the brief introduction of Information Security and some important terms relevant to it. Then they will learn about Firewall, Needs, Characteristics and Limitations of Firewall. While learning they will be engaged in interesting activities, discussions and games.
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. Goals: Aims/Outcomes-
1.Be familiarized with the term Information Security and its requirement.
