Abstract
In some examples, a system executes a monitor separate from an operating system (OS) that uses mapping information in accessing data in a physical memory. The monitor identifies, using the mapping information, invariant information, that comprises program code, of the OS without suspending execution of the OS, the identifying comprising the monitor accessing the physical memory independently of the OS. The monitor determines, based on monitoring the invariant information of the OS, whether a security issue is present.
