Creating Tearline documents for cross domain access using Solaris 10 with Trusted Extensions
By user12611852 on May 31, 2007
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.
Why should you care?
Sharing 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.
