Discover the ins and outs of Java security Part 3. This article, the first in a series, will cover the general concepts of computer security and cryptography. Although mobile code is not a revolutionary concept, Java and the Internet present some unique challenges to computer security. The evolution of Java architecture and its impact on security, the different security APIs and tools, and applet security will be covered in the subsequent articles. This security series does not intend to provide a comprehensive guide to computer security.
