  SECURITY: NSA Security-enhanced Linux updated (Howard Holm)

Subject: SECURITY: NSA Security-enhanced Linux updated
From: Howard Holm <hdholm@epoch.ncsc.mil>

The SELinux web site <http://www.nsa.gov/selinux/> including the mail
list archive has been updated.  SELinux kernel patches for 2.6.0-test6
and 2.4.21 are available.  The updated kernel patches include support
for an selinux boot parameter and improved auditing.  A number of
bugfixes and improvements have been integrated into the user space tools
and utilities.  SRPMs for newer Red Hat packages are available.  The
star package has been added.  The example policy has been updated. 
Improvements have been made to existing policy tools, and a new policy
analysis tool has been added.

Security-enhanced Linux incorporates a strong, flexible mandatory
access control architecture into the major subsystems of the Linux
kernel. The system provides a mechanism to enforce the separation of
information based on confidentiality and integrity requirements.  This
allows threats of tampering and bypassing of application security
mechanisms to be addressed and enables the confinement of damage that
can be caused by malicious or flawed applications.  The SELinux web
site <http://www.nsa.gov/selinux/> contains background information,
documentation, source code, and archives for the selinux mailing-list.
