Instance based security in Java

If your application needs instance based access control there is not a big variety of solutions out there. Here are some helpful links I found while searching on the internet listed in no particular order.

• Apache Shiro
• SAF – Security Annotation Framework (Targeted at Spring applications)
• Security Features of JBoss AS 5.1.0
• ACL Security in Seam
• Spring Security
• Fine-grained Java EE authorization using Enum-based access control lists with EAz
• Java Package java.security.acl (out-dated)
