F5 is an American technology company that has been operating since 1996 and it works specializes in application security, cloud management, online fraud prevention, application delivery network (ADN), network security, access and licensing. One of the most popular and famous products of this company is BIG-IP firewalls. In general, F5 firewalls are a good option to protect data centers against any internal and external threats by providing appropriate security solutions. The software uses the TMOS architecture designed by the company itself, which was first introduced in 2004 with version 9.0 of the BIG-IP firewall. The TMOS architecture is based on the Linux operating system and uses a traffic management microkernel (TMM) to communicate directly with network hardware and manage all network activity. This architecture creates a standard full-proxy mode that completely disconnects the network connections in the big-ip and establishes new connections between the big-ip and the server members in one assembly. This allows the user to have optimal TCP class on both sides of the connection that allow traffic to change in either direction. The hardware part of BIG-IP firewalls is divided into SYSTEM, VIPTION and VELOS categories.
