II. History and Definition of Data Security
History
Since the invention of writing, heads of states and military commanders understood that it was necessary to provide some mechanism to protect the confidentiality of written correspondence and to have some means of detecting tampering. Julius Caesar is credited with the invention of the Caesar cipher ca. 50 B.C. (Caesar’s Cipher - Data Encryption), which was created in order to prevent his secret messages from being read should a message fall into the wrong hands. World War II brought about much advancement in information security and marked the beginning of the professional field of data security.
The end of the 20th century and early years of the 21st century saw rapid advancements in telecommunications, computing hardware and software, and data encryption. The availability of smaller, more powerful and less expensive computing equipment made electronic data processing within the reach of small business and the home user. These computers quickly became interconnected through a network generically called the Internet.
The rapid growth and widespread use of electronic data processing and electronic business conducted through the Internet, along with numerous occurrences of international terrorism, fueled the need for better methods of protecting the computers and the data they store, process and transmit. The academic disciplines of computer security, information security and information assurance emerged along with numerous professional organizations. They are all sharing the common goals of ensuring the security and reliability of data systems.
