Security: Access control
Control use of systems and data
Security support and updates
Granting access to a resource is contingent on authenticating the user requesting the access and determining whether they are authorized to make the kind of access that they are requesting.
SELinux and MAC
Some operating systems rely on password protection, course-grained permissions, or ad hoc application controls to implement access control. Red Hat® Enterprise Linux® offers Security-Enhanced Linux (SELinux), a revolutionary and more powerful approach, built directly into the Linux kernel. SELinux provides mandatory access control (MAC), a security feature crucial for a trusted operating system. And Red Hat Enterprise Linux 4 and 5 have both received Common Criteria validation as such.
JBoss Enterprise Data Services Platform
JBoss® Enterprise Data Services Platform provides operations that are consistent with the datacenter-wide view of identity and authentication. This lets applications apply fine-grained access controls directly to information processing business logic.
