These consist of the protocols that define the format and structure of data and information that is either accessed from a directory or exchanged through communications.
- File Transfer Protocol (FTP)
A protocol used to transfer files over a TCP/IP network (Internet, UNIX, etc.). For example, after developing the HTML pages for a Web site on a local machine, they are typically uploaded to the Web server using FTP.
- Hyper Text Transfer Protocol (HTTP)
The communications protocol used to connect to servers on the World Wide Web. It’s primary function is to establish a connection with a web server and transmit HTML pages to the client browser.
- Hyper Text Transfer Protocol Secure (HTTPS)
The protocol for accessing a secure Web server. Using HTTPS in the URL instead of HTTP directs the message to a secure port number rather than the default Web port number of 80. The session is then managed by a security protocol.
- Internet Protocol (IP)
This is the protocol of the Internet and has become the global standard for communications. IP accepts packets from TCP, adds its own header and delivers a “datagram” to the data link layer protocol. It may also break the packet into fragments to support the maximum transmission unit (MTU) of the network.
- IP Security (IPSEC)
A set of protocols used to secure IP packet exchange. Tunnel and Transport are the two (2) modes supported by IPSEC. IPSEC uses certificates and Public Keys to authenticate and validate the sender and receiver.
- Transport Control Protocol (TCP)
TCP provides transport functions, which ensures that the total amount of bytes sent is received correctly at the destination.
- Wireless Application Protocol (WAP)
The Wireless Application Protocol (WAP) is an open, global specification that empowers users of digital mobile phones, pagers, personal digital assistants and other wireless devices to securely access and interact with Internet/intranet/extranet content, applications, and services.
