Next Generation Firewall - An Introductory Use Case

Master's thesis

Abstract:

Traditional firewalls were unable to differentiate between different forms of web traffic and simply followed internet protocols. Due to their inability to analyse the contents of network packets and discern between legitimate business applications and threats, they were forced to accept or reject all traffic. SSL traffic cannot be examined or decoded by a traditional firewall. A firewall is a piece of hardware or software that prevents unauthorized access to a computer system for the purposes of this issue statement. A next-generation firewall (NGFW) is a system security architecture that is based on hardware or software that has security features to identify and stop attacks at the application, port, and convention levels. Since the firewall is the first line of defence against such attacks and business system security is essential, firewall technology has evolved to address the problem. Traditional firewalls have failed because they lack granular insight into identifying distinct types of web activity and are unable to inspect the information payload of system packets. The overall goal is to investigate how the Next Generation Firewall is used and how it functions within a large and complicated network. It can be determined that the Next-Generation Firewall performs much better in terms of neutralising attacks launched by external users on a company network compared to traditional firewall. It can improve the security of data communication networks against external network attacks.
