NSA Security-enhanced Linux

Subject:  SECURITY: NSA Security-enhanced Linux updated
Date:  Sat, 14 Dec 2002 22:38:13 CST

The SELinux web site <http://www.nsa.gov/selinux/> including the mail
list archive has been updated.  The site includes a new release of the
LSM-based SELinux prototype. The base kernel versions have been updated
to 2.4.20 and 2.5.51.  Initial SID and context for SCMP packets has been
added.  Additional policy enhancement and patch contributions have been
merged. The logrotate patch has been updated to 3.6.5-2. The private
file oversight in LSM, inode_doinit bug in SELinux, and selopt compile
problems have all been fixed.

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.
