John Weeks of Sun has created an interesting application using Java for Solaris 10 Trusted Extensions.
It implements "tearlines" that allow a single document to be viewed
differently by users with different levels of classification on the
system. A "Public" user might only see the basic description of a
Sun bug report, for example, while an "Internal" user would see the
basic description along with internal information such as responsible
engineer, comments, release schedule etc.
Review John's presentation from JavaOne. Read more about it in the sidebar to this Government Computer News article.
Why should you care?
information has become a high priority for the US Government agencies
responsible for defense and homeland security. However, proper
precautions must be taken to ensure that the right people see only the
information they are allowed to see by law or policy. Solaris 10
with built in Trusted Extensions facilitates this capability by
providing a mature multi-level operating system.
This feature is available on Sun's Sparc, Intel and AMD platforms as well as those from other vendors such as IBM, Dell and HP.
