For a project such as OpenVZ, security of the software is of paramount importance. Let's explain how we assure that OpenVZ is secure.
Kernel
The OpenVZ kernel is based on the Linux kernel. The OpenVZ team tracks and analyzes all the security updates to the Linux kernel and applies them accordingly.
To achieve the maximum possible security and stability, stable OpenVZ kernels are based on Red Hat Enterprise Linux kernels, which are conservative and well-maintained. By using an enterprise kernel as a base (rather than latest vanilla kernel), we avoid adding new bugs or security holes, still the old ones are getting discovered and fixed, and the kernel matures.
