Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network. The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible.
The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on Internet Protocol (IP) networks for automatically assigning IP addresses and other communication parameters to devices connected to the network using a client–server architecture.
A High Assurance Internet Protocol Encryptor ( HAIPE) is a Type 1 encryption device that complies with the National Security Agency 's HAIPE IS (formerly the HAIPIS, the High Assurance Internet Protocol Interoperability Specification). The cryptography used is Suite A and Suite B, also specified by the NSA as part of the Cryptographic ...
Internet Connection Sharing ( ICS) is a Windows service that enables one Internet -connected computer to share its Internet connection with other computers on a local area network (LAN). The computer that shares its Internet connection serves as a gateway device, meaning that all traffic between other computers and the Internet go through this ...
The Secure Real-time Transport Protocol ( SRTP) is a profile for Real-time Transport Protocol (RTP) intended to provide encryption, message authentication and integrity, and replay attack protection to the RTP data in both unicast and multicast applications. It was developed by a small team of Internet Protocol and cryptographic experts from ...
Secure network address translation (SNAT) is part of Microsoft's Internet Security and Acceleration Server and is an extension to the NAT driver built into Microsoft Windows Server. It provides connection tracking and filtering for the additional network connections needed for the FTP , ICMP , H.323 , and PPTP protocols as well as the ability ...
An application-level gateway ( ALG, also known as application layer gateway, application gateway, application proxy, or application-level proxy) is a security component that augments a firewall or NAT employed in a mobile network. [1] [2] It allows customized NAT traversal filters to be plugged into the gateway to support address and port ...
Secure Socket Tunneling Protocol ( SSTP) is a form of virtual private network (VPN) tunnel that provides a mechanism to transport PPP traffic through an SSL/TLS channel. SSL/TLS provides transport-level security with key negotiation, encryption and traffic integrity checking. The use of SSL/TLS over TCP port 443 (by default; port can be changed ...
