摘要： In some embodiments, a system is provided, comprising enforcement hardware configured to execute, at run time, a state machine in parallel with application code. Executing the state machine may include: maintaining metadata that corresponds to one or more state variables of the state machine; matching instructions in the application code to transitions in the state machine; and, in response to determining that an instruction in the application code does not match any transition from a current state of the state machine, causing an error handling routine to be executed. In some embodiments, a description of a state machine may be translated into at least one policy to be enforced at run time based on metadata labels associated with application code and/or data manipulated by the application code.

摘要： Systems and methods for stalling a host processor. In some embodiments, the host processor may be caused to initiate one or more selected transactions, wherein the one or more selected transactions comprise a bus transaction. The host processor may be prevented from completing the one or more selected transactions, to thereby stall the host processor.

摘要： A system including at least one processor programmed to translate a policy into policy code, wherein: the policy is provided in a policy language; the policy code is in a programming language that is different from the policy language; and the policy includes a statement that maps an entity name to one or more metadata symbols to be associated with an entity in a target system against which the policy is to be enforced.

摘要： A system including at least one processor programmed to identify, based on a policy to be enforced, one or more metadata symbols corresponding to an entity name; identify, from a target description describing a target system, an entity description matching the entity name, wherein the entity description describes an entity of the target system; and apply a metadata label to the entity of the target system, wherein the metadata label is based on the one or more metadata symbols corresponding to the entity name, as identified based on the policy.

摘要： Systems and methods for updating metadata. In some embodiments, in response to detecting an instruction executed by a hardware system, a source location of the instruction may be identified. First metadata associated with the instruction may be used to determine whether the instruction is allowed. In response to determining that the instruction is allowed, the source location of the instruction may be associated with second metadata.

摘要： A system including at least one processor programmed to identify, based on a policy to be enforced, one or more metadata symbols corresponding to an entity name; identify, from a target description describing a target system, an entity description matching the entity name, wherein the entity description describes an entity of the target system; and apply a metadata label to the entity of the target system, wherein the metadata label is based on the one or more metadata symbols corresponding to the entity name, as identified based on the policy.
