Ksplice

Ksplice is a new technology for protecting the security and reliability of machines on the network. Currently, all computer systems need to be rebooted regularly to apply OS updates, in order to be secure against potential attacks over the network. Ksplice makes it possible for system administrators and end-users to perform OS updates effortlessly, without a reboot. This project will make an open source Linux distribution be the first operating system in the world that does not require regular reboots for security updates.

This technology also has the potential to significantly hinder network attackers by reducing the window of vulnerability during which computer systems are running software with known problems.

Thus, Ksplice solves the underlying weakness in the system so that no malicious activity, no matter how it has been disguised, will be able to achieve its objective of compromising the system.
