Introduction The AIC triad is one of the many approaches to secure networks in today's complex computing environments. What makes the AIC triad different from any other theory is that when it is used properly it forms the cornerstone of every aspect of computing and network security. Most IT security practices are focused on protecting systems from loss of confidentiality, loss of integrity, and loss of availability; these three together are referred to as the security triad, the CIA triad, and

In this method the sender uses a key with some enhanced rules and regulations to encrypt the simple text (plain text) into cipher text that need to send to receiver. The receiver also applies the same enhanced rules to decrypt the cipher text in-order to get the Original content of the message. Actually a single key employs for both process, so it is called as symmetric key cryptography. Figure 1.1 Specific Key Cryptography Secret key cryptography contains continuous ciphers (stream

adopted by millions of websites in the protection of their online business with their customers. SSL defines a secured abstraction layer of communication on the existing network infrastructure. Once the secure connection is established, the session key will be used to encrypt all transmitted data over the network. Web browser connects to a web server (for example, website) using secured SSL connection. However, the browser requests the server identify itself in order to establish the secured connection

connected directly or indirectly to the internet. PGP(Pretty Good Privacy) is an open-source freely available software for E-Mail security. It provides authentication through the use of digital signature, confidentiality through the use of symmetric block encryption, compression using the ZIP algorithm, E-Mail compatibility using the radix-64 encoding scheme and segmentation and reassembly to accommodate long e-mails.
