The Java software platform provides a number of features designed for improving the security of Java applications. This includes enforcing runtime constraints through the use of the Java Virtual Machine (JVM), a security manager that sandboxes untrusted code from the rest of the operating system, and a suite of security APIs that Java developers can utilise.
Java Authentication and Authorization Service, or JAAS, pronounced "Jazz", [1] is the Java implementation of the standard Pluggable Authentication Module (PAM) information security framework. [2] JAAS was introduced as an extension library to the Java Platform, Standard Edition 1.3 and was integrated in version 1.4.
Protection relies upon hardware memory protection and thus overhead is typically not substantial, although it can grow significantly if the program makes heavy use of allocation. [16] Randomization provides only probabilistic protection against memory errors, but can often be easily implemented in existing software by relinking the binary.
At the language level, Java Card is a precise subset of Java: all language constructs of Java Card exist in Java and behave identically. This goes to the point that as part of a standard build cycle, a Java Card program is compiled into a Java class file by a Java compiler; the class file is post-processed by tools specific to the Java Card ...
The particular logical access controls used in a given facility and hardware infrastructure partially depend on the nature of the entity that owns and administrates the hardware setup. Government logical access security is often different from business logical access security, where federal agencies may have specific guidelines for controlling ...
A forgeable reference (for example, a path name) identifies an object, but does not specify which access rights are appropriate for that object and the user program which holds that reference. Consequently, any attempt to access the referenced object must be validated by the operating system, based on the ambient authority of the requesting ...
