Final answer:
IPSec is an IETF standard that provides security services at the IP layer by securing and authenticating IP packets.
Step-by-step explanation:
IPSec is a collection of Internet Engineering Task Force (IETF) standards that define an architecture at the Internet Protocol (IP) layer that protects IP traffic by using various security services. Unlike SSL/TLS and HTTPS, which secure data at the transport layer, or SSH, which provides secure shell access, IPSec operates at the IP layer to secure and authenticate IP packets. It ensures data integrity, data confidentiality, and data authentication between hosts across an IP network.
TEC officers have taken individual membership of IETF. TEC participates in various working groups of IETF responsible for standardization of the Internet’s core protocols (both IPv4 and IPv6), submitting contributions in the meetings, working with technical bodies' work programs, and having access to the most up-to-date information on Internet standards.
The various activities of IETF in which TEC participates include: -
Applications and Real-Time Art (ART)
The ART area develops application protocols and architectures in the IETF. The work in the area falls into roughly three categories, with blurry distinctions between them. One category consists of protocols and architectures specifically designed to support delay-sensitive interpersonal communications via voice, video, instant messaging, presence, and other means, otherwise known as "real-time" applications and services.
A second category consists of protocols and architectures to support applications that may be more tolerant of delay, including HTTP, email, and FTP. The third category consists of building blocks that are designed for use across a wide variety of applications and may be employed by both real-time and non-real-time applications, such as URI schemes, MIME types, authentication mechanisms, data formats, metrics, and codecs.
