Description: Authenticated exploit on device Host in Space via connection with RemoteHost: an attacker with access to RemoteHost in location Space can send a malicious message via its pairing connection with Host that, after authentication, can exploit a bug in Host.

Threat Type: Primary Threat

Matching Pattern:

CSG-PatchingAtHost

Use a systematic procedure for regular security patching of software used (including hosted processes) on device Host, and have a contingency plan included in the system operating policies and practices for HostManager to manually apply patches immediately should the need for them become urgent.

CSG-PatchingAtHost-Implementation

Represents a situation in which software patches have been applied manually by HostManager to eliminate vulnerabilities in device Host. This strategy represents activation of a contingency plan at runtime, and can be selected to discover what effect this would have on risk levels, allowing this to be used for decision support calculations. Note that this should only be considered if a suitable software patch is available. To implement this at runtime, signal the responsible user HostManager. Then deselect the SoftwarePatched control and restore the asserted Extrinsic TW levels of Host once the update has been confirmed.
