Abstract
Disclosed embodiments relate to secure and reliable customization of operating system kernels. Techniques include configuring a kernel security module for loading to an operating system kernel to run kernel-level scripts on the kernel, the kernel security module being configured to perform a security verification comprising operations of: identifying, at the kernel security module, a script received at the kernel security module for requested execution by the kernel, and verifying whether the script has a valid signature; determining, at the kernel security module and based on the security verification, whether to permit the script to be processed by the kernel; and identifying, based on the determining, executable code corresponding to the script to execute at the kernel.
