We all live in a digital world and it has become a mandate to understand the web even more well. Today we will read about PIX NETWORK. PIX (Private Internet Exchange) Firewall provides full firewall protection that completely conceals the architecture of an internal network from the outside world. PIX Firewall allows secure access to the Internet from within existing private networks and the ability to expand and reconfigure TCP/IP networks without being concerned about a shortage of IP addresses. With PIX Firewall, users can take advantage of larger address classes than they may have been assigned by the Internet’s Network Information Center (NIC). PIX Firewall provides this access through its Network Address Translation (NAT) facility as described by reference article that till date holds great importance and information

PIX Firewall Adaptive Security

The Adaptive Security (AS) feature applies to the dynamic translation slots and can be applied to static translation slots via the static command. The Adaptive Security algorithm is a very stateful approach to security. Every inbound packet is checked exhaustively against the Adaptive Security algorithm and against connection state information in memory. This stateful realistic and actual approach to security is regarded in the industry as being far more secure than a stateless packet screening approach.

PIX Firewall Features

With the firewall feature, you can eliminate the overhead and risks associated with UNIX-based firewall systems and have complete accounting and logging of all transactions, including attempted break-ins. Both NCSA and SRI certify that the PIX Firewall secures your network from outside intrusion.

PIX Firewall has the following features:

•Firewall capability that keeps intruders out of your internal network while permitting regulated conduit access through the firewall for services such as electronic mail, Telnet, FTP, SNMP, and HTTP (World Wide Web) use.

•Network translation services that let a site share one or more NIC-registered IP addresses among many users.

•An Identity feature that lets NIC-registered IP addresses pass through the firewall without address translation, while still retaining Adaptive Security.

•The PIX Firewall offers performance dramatically better than competing firewalls. It gains speed through a patent pending process called Cut-Through proxies, which is the fastest way for a firewall to authenticate a user. Unlike a proxy server that must analyze every packet at layer seven of the OSI model, a time- and processing-intensive function, the PIX Firewall first queries a TACACS+ or RADIUS server for authentication. Once approved, the PIX Firewall then establishes a data flow and all traffic thereafter flows directly and quickly between the two parties. This Cut-Through capability allows the PIX Firewall to perform dramatically faster than proxy-based servers while maintaining session state.

•An IOS-like command set for simplified configuration and administration.
