Cisco PIX - Wikipedia. Cisco PIX (Private Internet e. Xchange) was a popular IPfirewall and network address translation (NAT) appliance. It was one of the first products in this market segment. In 2. 00. 5, Cisco introduced the newer Cisco Adaptive Security Appliance (Cisco ASA), that inherited many of the PIX features, and in 2. PIX end- of- sale. The PIX technology was sold in a blade, the Fire. Wall Services Module (FWSM), for the Cisco Catalyst 6. Router series, but has reached end of support status as of September 2. The PIX name is derived from its creators' aim of creating the functional equivalent of an IP PBX to solve the then- emerging registered IP address shortage. At a time when NAT was just being investigated as a viable approach, they wanted to conceal a block or blocks of IP addresses behind a single or multiple registered IP addresses, much as PBXs do for internal phone extensions. When they began, RFC 1. RFC 1. 63. 1 were being discussed, but the now- familiar RFC 1. The design, and testing were carried out in 1. John Mayes, Brantley Coile and Johnson Wu of Network Translation, Inc., with Brantley Coile being the sole software developer. Beta testing of PIX serial number 0. December 2. 1, 1. KLA Instruments in San Jose, California. The PIX quickly became one of the leading enterprise firewall products and was awarded the Data Communications Magazine . Together they continued development on Finesse OS and the original version of the Cisco PIX Firewall, now known as the PIX . During this time, the PIX shared most of its code with another Cisco product, the Local. Director. On January 2. Cisco announced the end- of- sale and end- of- life dates for all Cisco PIX Security Appliances, software, accessories, and licenses. The last day for purchasing Cisco PIX Security Appliance platforms and bundles was July 2. The last day to purchase accessories and licenses was January 2. Cisco ended support for Cisco PIX Security Appliance customers on July 2. The ASA series of devices run PIX code 7. Through PIX OS release 7. PIX and the ASA use the same software images. Beginning with PIX OS version 8. ASA using a Linux kernel and PIX continuing to use the traditional Finesse/PIX OS combination. Though classified as a network- layer firewall with stateful inspection, technically the PIX would more precisely be called a Layer 4, or Transport Layer Firewall, as its access is not restricted to Network Layer routing, but socket- based connections (a port and an IP Address: port communications occur at Layer 4). By default it allows internal connections out (outbound traffic), and only allows inbound traffic that is a response to a valid request or is allowed by an Access Control List (ACL) or by a conduit. Administrators can configure the PIX to perform many functions including network address translation (NAT) and port address translation (PAT), as well as serving as a virtual private network (VPN) endpoint appliance. The PIX became the first commercially available firewall product to introduce protocol specific filtering with the introduction of the . Protocols for which specific fixup behaviors were developed include DNS and SMTP. The DNS fixup originally implemented a very simple but effective security policy; it allowed just one DNS response from a DNS server on the Internet (known as outside interface) for each DNS request from a client on the protected (known as inside) interface. They can access the CLI from the serial console, telnet and SSH. GUI administration originated with version 4. Starting with version 7. IOS- like. As the PIX only supports IP traffic (as opposed to IPX, DECNet, etc.), in most configuration commands . The configuration is upwards- compatible, but not downwards- compatible. When a 5. x or 6. ACLs, versus conduits and . This allows for an easy migration from PIX to ASA. PIX OS v. 7. 0 is only supported on models 5. E), 5. 25 and 5. 35. Although the 5. 01 and 5. E are relatively recent models, the flash memory size of only 8 MB prevents official upgrading to version 7. E using monitor mode up to version 7. The 8 MB flash size only allows for installation of the PIX OS software, not the ASDM software (GUI). For the PIX 5. 15(E) to run version > 7. MB for restricted and 6. MB for Unrestricted/Failover licenses). A 5. 15(E) UR/FO can run 7. MB memory installed, but that is not recommended as larger configuration and session/xlate tables can exceed the available memory. Cisco ASA includes the capability of detecting and terminating connections via Dead Connection Detection (DCD). All flash cards and the early encryption acceleration cards, the PIX- PL and PIX- PL2, were sourced from Productivity Enhancement Products (PEP). Nearly all PIXs used Ethernet. NICs with Intel 8. COM 3c. 59. 0 and 3c. Ethernet cards, Olicom- based Token- Ring cards, and Interphase- based FDDI cards. Some Intel- based Ethernet cards for the PIX are identified at boot with the designation . This designation denotes a multicast receive bug in the card's firmware. Both the PIX 5. 10 and 5. NICs, flash cards, etc., with the Cisco Local. Director 4. 16/4. Service Selector Gateway 6.

This results in a much higher cleartext throughput, as the PCI bus is no longer the bottleneck (the PCI bus is 3. MHz and 3. 2 bits, resulting in maximum throughput of 1.

It is manufactured by Productivity Enhancement Products. Aside from progressive manufacturing refinements, the 5. KB and 2 MB flash cards were identical aside from the chips that populated it. Both booted from a 2. F2. 56 chip, but the 5. KB card only populated two of the flash sockets with 2. F0. 20 chips, while the 2 MB card populated all four sockets with 2.

Equation Group was later hacked by another group called The Shadow Brokers, which published their exploit publicly, among others. The vulnerability requires that both SSH and SNMP are accessible to the attacker. The codename given to this exploit by NSA was EXTRABACON. The bug and exploit (CVE- 2. According to Ars Technica, the exploit can easily be made to work against more modern versions of Cisco ASA than what the leaked exploit can handle. For PIX- 5. 25, RAM configurations above 3.
