Detailed explanation-1: -Explanation: Application layer firewalls are also called third generation firewalls. They came into the picture in around 1995-1998. Application level gateway firewalls are helped in making the network performance smooth for logging traffic.
Detailed explanation-2: -A next-generation firewall (NGFW) is a part of the third generation of firewall technology, combining a traditional firewall with other network device filtering functions, such as an application firewall using in-line deep packet inspection (DPI), an intrusion prevention system (IPS).
Detailed explanation-3: -Application layer gateway firewalls also known as proxy based firewalls can monitor and filter on the application layer (Layer 7), as well as doing the traditional filtering such as packet filtering and stateful packet inspection.
Detailed explanation-4: -There are three types of firewalls based on how you decide to deploy them: hardware, software, and cloud-based firewalls.
Detailed explanation-5: -Second-generation firewalls: Proxy services. The next generation of firewalls attempted to increase the level of security between trusted and untrusted networks. Known as application proxy or gateway firewalls, this approach to protection is significantly different from packet filters and stateful packet inspection.
