2. TOPICS Definition of firewall Importance of firewalls Functionality of firewalls Types of firewalls Best practices for firewall management Future challenge and trends

3. DEFINITION OF FIREWALL A firewall is a network security device that monitors and filters incoming and outgoing network traffic based on an organization’s previously established security policies.

4. Example: PACKET FILTERING Operate inline at junction point were device such as routers and switches do their work.

6. FUNCTIONALITY OF FIREWALLS A firewall is a security system designed to prevent unauthorized access into or out of a computer network.

7. TYPES OF FIREWALLS P acket filtering firewall. Circuit-level gateway. Application-level gateway, aka proxy firewall. Stateful inspection firewall. Next-generation firewall.

8. BEST PRACTICES FOR FIREWALL Harden and configure firewalls properly. Adopt a customized, phased deployment strategy. Enhance and regularly update firewall protocols. Regularly review and update access controls.

9. BEST PRACTICES FOR FIREWALL Implement a comprehensive logging and alert mechanism. Establish backup and restoration protocols. Subject firewalls to regular testing. Conduct routine firewall audits.

10. FUTURE CHALLENGE AND TRENDS In order to really know a story, you need to have been there… or at least heard about it first hand. We wanted to know about the current market challenges and which business trends are guiding us towards the future.
