Security & Compliance

When a security loophole in the Linux kernel is identified, patching systems are the only way to minimize your exposure to a potential malicious attack. Patching often requires stopping the system. What if you are not allowed to interrupt service? SUSE Linux Enterprise Live Patching is the answer. It allows you to apply Linux kernel patches without any downtime.

Zero Execution Interruption

Stopping the Linux kernel is problematic for low-latency applications such as simulations and real-time applications. These applications don’t allow interruptions for even a millisecond, or they must be restarted. SUSE Linux Enterprise Live Patching doesn't stop the system during patching, ensuring that your mission-critical workloads run without downtime.

Fully Integrated Deployment

The patches in SUSE Linux Enterprise Live Patching are delivered as signed RPMs through a dedicated update channel. Introducing Live Patching into your established administrative process is simple because you can easily reuse your existing deployment methods including, but not limited to, YaST, Zypper, Subscription Management Tool (SMT), and SUSE Manager.
