Other Hooks

LSM provides two additional sets of hooks: module hooks and a set of top-level system hooks. Module hooks can be used to control the kernel operations that create, initialize, and delete kernel modules. System hooks can be used to control system operations, such as setting the system hostname, accessing I/O ports, and configuring process accounting. The existing Linux kernel provides some control over many of these operations using the capability checks, but those checks only provide coarse-grained distinctions among different operations and do not provide any argument information.
