Keeping resources secure is an ongoing challenge. As defenses are implemented, new methods are devised to circumvent them. The following is a short list of the many excellent sites that contain security related information:
The JavaWorld’s bookstore security reference page http://www.javaworld.com/javaworld/books/jw-books-security.html
A good source of cryptographic related information is available from RSA laboratories ftp://ftp.rsasecurity.com/pub/labsfaq/labsfaq4.pdf.
The Java security pagehttp://java.sun.com/security/
