Security, networking speed and container-based virtualization are the focus of the latest enhancements in Red Hat Enterprise Linux 7.2, the newest release of Red Hat‘s open source OS.
RHEL 7.2, which debuted Thursday, includes the following enhancements:
An OpenSCAP plug-in for Anaconda, the RHEL installer, which allows users to verify that the packages they install on their systems during setup have not been subject to tampering.
DNSSEC support for preventing DNS spoofing and other DNS-related security attacks.
Tweaks to packet processing, support for TCP (DCTCP) and other updates to the networking stack. Networking throughput has been “doubled in many network function virtualization (NFV) and software defined networking (SDN) use cases” in RHEL 7.2, according to Red Hat.
Updates to container software packages, including Docker and Atomic Host. In addition, RHEL 7.2 includes the beta release of the Red Hat Container Development Kit 2 for building container-based applications.
A backup and disaster-recovery tool called Relax-and-Recover.
None of these changes totally revolutionizes RHEL, but they make the platform more robust and easier to administer in several of the areas that matter most, especially security and networking.
