<br/><br/> "The book starts with information security principles, and public key cryptography is discussed further, a commonly used cryptographic method used to encrypt data is also discussed. Unlike symmetric cryptography, which uses a single key, this type of system is considered asymmetric because it relies on a pair of keys. The book also presents the coverage on the legal and ethical issues of securities. It closes with a focus on security threat and attack today."
