Abstract: Technologies are disclosed for using hardware-embedded monitors to monitor pages of local memory and detect attribute violations or other unauthorized operations relating to the memory. The attribute violations may include mismatches of attributes (e.g., designating a page as writeable versus executable or vice versa) in entries in a translation buffer that point to a same physical address or other mismatches between designations of attributes for a page in physical and virtual space. Responsive to detecting a violation, an alert or other mitigation protocol, which may include an audit of activities surrounding the violation, may be performed.
