From the Gubment dept.:
During Red Hat's official launch event for their new Red Hat Enterprise Linux 6 (RHEL 6) release, executives from the company focused heavily on new performance gains. While performance and scalability are key elements of RHEL 6, so too is security.

With RHEL 6, Red Hat is debuting a number of new features into its enterprise Linux, including new virtual security services as well as the System Security Services Daemon. Security services aren't the only area of RHEL 6 built for security, as all RHEL 6 packages now benefit from a new 4096-bit RSA hardware signing key as well
