d

to the access control list (ACL) entries. This entry identifies specific types of packets that can be sent to each host and all other traffic is blocked. It will also check the MAC address of a requester to determine whether the device being used are able to make the connection is authorized to access the data or not.


Hybrid firewalls

It is a type of firewalls which combine features of other four types of firewalls. These are elements of packet filtering and proxy services, or of packet filtering and circuit gateways.


2. Development Era:

Firewall can be categorised on the basis of the generation type. These are-


First Generation

Second Generation

Third Generation

Fourth Generation

Fifth Generation

First Generation:

The first generation firewall comes with static packet filtering firewall. A static packet filter is the simplest and least expensive forms of firewall protection. In this generation, each packet entering and leaving the network is checked and will be either passed or rejected depends on the user-defined rules. We can compare this security with the bouncer of the club who only allows people over 21 to enter and below 21 will be disallowed.


Second Generation:

Second generation firewall comes with Application level or proxy servers. This generation of firewall increases the security level between trusted and untrusted networks. An Application level firewall uses software to intercept connections for each IP and to perform security inspection. It involves proxy services which act as an interface between the user on the internal trusted network and the Internet. Each computer communicates with each other by passing network traffic through the proxy program. This program evaluates data sent from the client and decides which to move on and which to drop.


Third Generation:

The third generation firewall comes with the stateful inspection firewalls. This generation of the firewall has evolved to meet the major requirements demanded by corporate networks of increased security while minimizing the impact on network performance. The needs of the third generation firewalls will be even more demanding due to the growing support for VPNs, wireless communication, and enhanced virus protection. The most challenging element of this evolution is maintaining the firewall's simplicity (and hence its maintainability and security) without compromising flexibility.


Fourth Generation:

The fourth generation firewall comes with dynamic packet filtering firewall. This firewall monitors the state of active connections, and on the basis of this information, it determines which network packets are allowed to pass through the firewall. By recording session information such as IP addresses and port numbers, a dynamic packet filter can implement a much tighter security posture than a static packet filter.


Fifth Generation:

The fifth generation firewall comes with kernel proxy firewall. This firewall works under the kernel of Windows NT Executive. This firewall proxy operates at the application layer. In this, when a packet arrives, a new virtual stack table is created which contains only the protocol proxies needed to examine the specific packet. These packets investigated at each layer of the stack, which involves evaluating the data link header along with the network header, transport header, session layer information, and application layer data. This firewall works faster than all the application-level firewalls because all evaluation takes place at the kernel layer and not at the higher layers of the operating system.


3. Intended deployment structure:

Firewall can also be categorized based on the structure. These are-


Commercial Appliances

It runs on a custom operating system. This firewall system consists of firewall application software running on a general-purpose computer. It is designed to provide protection for a medium-to-large business network. Most of the commercial firewalls are quite complex and often require specialized training and certification to take

full advantage of their features.
