About the Book

Cryptography is the practise, study, and development of techniques for secret communication, including the transformation of readable text into an unreadable one and vice again. The data on one computer may be transmitted to another computer outside of a safe environment. Once your information is out in the wild, malevolent actors may alter it or fabricate it for their own ends. With the use of cryptography, our information may be reorganised and transformed to ensure its security while in transit between computers. The purpose of this book is to provide a practical survey of both the principles and practice of cryptography and network security. First, the basic issues to be addressed by a network security capability are explored through a tutorial and survey of cryptography and network security technology. Then, the practice of network security is explored via practical applications that have been implemented and are in use today.
