We'll also discuss how policy files, which accord permissions and keystore, can be used as a repository for public and private keys. Moreover, we'll highlight the Java 2 SDK security tools and Netscape's signtool , since they enable deployment. This article traces the evolution of Java security, beginning with application security in the initial release of Java 2 and moving on to the latest version of Java 2, version 1.3. This approach helps introduce the concepts gradually, starting with very simple concepts and culminating in a fairly advanced example. This series does not intend to provide a comprehensive guide to computer security.
Computer security is a multifaceted issue touching several disciplines, departments, and cultures.
Investments in technologies should be followed up with investments in personnel training, strict enforcement of policies, and periodic review of the overall security policy. Read below for more details. Application security Let's begin our investigation by looking at application security. In Part 2 we saw how Java security has evolved from a sandbox model to a fine-grained security model. In a change from the past, in Java 2 security applications can be optionally subject to the same level of control as applets.
