Network address translation between a private network and the Internet. Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. [1]
Various NAT traversal techniques have been developed: NAT Port Mapping Protocol (NAT-PMP) is a protocol introduced by Apple as an alternative to IGDP. Port Control Protocol (PCP) is a successor of NAT-PMP. UPnP Internet Gateway Device Protocol (UPnP IGD) is supported by many small NAT gateways in home or small office settings. It allows a ...
Logo. The Common Vulnerabilities and Exposures (CVE) system provides a reference method for publicly known information-security vulnerabilities and exposures. [1] The United States' National Cybersecurity FFRDC, operated by The MITRE Corporation, maintains the system, with funding from the US National Cyber Security Division of the US Department of Homeland Security.

Network access control is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network. [3]
One of the earliest commercially successful firewall and network address translation (NAT) products was the PIX (Private Internet eXchange) Firewall, invented in 1994 by Network Translation Inc., a startup founded and run by John Mayes. The PIX Firewall technology was coded by Brantley Coile as a consultant software developer. [9]
Network security are security controls, policies, processes and practices adopted to prevent, detect and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. [1]
The National Institute of Standards and Technology (NIST), a U.S. federal agency under the Department of Commerce, plays a central role in developing and maintaining cybersecurity standards, guidelines, and best practices. Initially created to ensure the security of federal information systems, NIST's standards have become globally influential ...
The NIST Cybersecurity Framework is meant to be a living document, meaning it will be updated and improved over time to keep up with changes in technology and cybersecurity threats, as well as to integrate best-practices and lessons learned. Since releasing version 1.1 in 2018, stakeholders have provided feedback that the CSF needed to be updated.
