J2EE™ Security for Servlets, EJBs and Web Services: Applying Theory and Standards to Practice

Toward the Solution

Solving a problem as complex as computer security needs a systematic and comprehensive approach. Before we get to that, let's talk about technologies that solve parts of the problem.

Enabling Technologies

A number of technologies, resources and processes have been developed to counter the threat of online security. Some of the prominent ones are discussed below:

Cryptography

The practice of keeping content secure from prying eyes is known as cryptography. A cryptographic algorithm or cipher is used to convert plain-text content to cipher-text through a process known as encryption and back to plaintext through the reverse process known as decryption. A key may be used during the encryption and decryption process. Algorithms ...
