A system includes a memory system and a processing system operably coupled to the memory system. The memory system includes a plurality of address spaces. The processing system is configured to perform operations including creating a data space from within a primary address space and a primary address space number access list entry referencing the data space. An unauthorized caller routine in a home address space configured to issue a service request including an address space-switching program call from the home address space to a program call target routine in the primary address space. The address space-switching program call references the primary address space number access list entry in the primary address space. A vulnerability identifier associated with the program call target routine is created and logged based on one or more conditions indicative of a cross-memory integrity violation detected responsive to the service request.

Cyber security for space-switching program calls

A system includes a memory system and a processing system operably coupled to the memory system. The processing system is configured to perform operations including setting a target register to point to a first protected storage location of the memory system resulting in a protection exception upon access, calling an authorized service, and confirming that the authorized service uses the target register based on detecting the protection exception. The target register is adjusted to point to a parameter list including one or more known values and a pointer to a second protected storage location resulting in the protection exception upon access to confirm use of a value of the parameter list responsive to calling the authorized service. Parameter list testing and target register testing is repeated for locations in the parameter list and target registers to construct a testing profile for vulnerability testing of the authorized service.

Cyber security testing for authorized services

Technical solutions are described for securing data by a communication apparatus. An example computer-implemented method includes receiving, by an encryption engine, a request to apply cryptography to input data. The computer-implemented method also includes generating metadata for the input data, where the metadata identifies characteristics of content included in the input data. The method further includes applying a cryptographic technique to the input data to generate output data, and outputting the output data and metadata in response to the request.

Privacy enabled runtime

Technical solutions are described for preventing unauthorized transmission of data by a communication apparatus. An example computer-implemented method includes monitoring a data transmission request from an application being executed by the communication apparatus. The data transmission request is associated with transmission data. The method further includes securing the transmission data, where the securing includes identifying a content of a predetermined type in the transmission data, and generating secured transmission data. The secured transmission data includes a corresponding modified version of the content of the predetermined type. The computer-implemented method also includes transmitting the secured transmission data in response to the data transmission request.

Embodiments are directed to a method of identifying an identification (ID) tag. The method includes using a movable reader to determine a presence of an ID tag, an absence of the ID tag and that the ID tag has moved. The method further includes using the movable reader to determine a localization probability score of the ID tag, and, based on the localization probability score, adjust the movable reader's determination of the presence of the ID tag.
