Is there a security framework or general tool that can be used to ensure that a certain process started at boot in Linux cannot be terminated by any user or other process, including the root user?

See SELinux. –  Steven Monday Apr 9 '11 at 20:05

In short: no. The root user can do anything without restriction. Even init can be killed by root (which brings the system down.)
