Utilize a two-person system to achieve a high level of security for systems with command level access to the spacecraft. Under this rule all access and actions require the presence of two authorized people at all times.
| ID | Name | Description | |
| IA-0007 | Compromise Ground System | Threat actors may initially compromise the ground system in order to access the target spacecraft. Once compromised, the threat actor can perform a multitude of initial access techniques, including replay, compromising FSW deployment, compromising encryption keys, and compromising authentication schemes. Threat actors may also perform further reconnaissance within the system to enumerate mission networks and gather information related to ground station logical topology, missions ran out of said ground station, birds that are in-band of targeted ground stations, and other mission system capabilities. | |
| .01 | Compromise On-Orbit Update | Threat actors may manipulate and modify on-orbit updates before they are sent to the target spacecraft. This attack can be done in a number of ways, including manipulation of source code, manipulating environment variables, on-board table/memory values, or replacing compiled versions with a malicious one. | |
| .02 | Malicious Commanding via Valid GS | Threat actors may compromise target owned ground systems components (e.g., front end processors, command and control software, etc.) that can be used for future campaigns or to perpetuate other techniques. These ground systems components have already been configured for communications to the victim spacecraft. By compromising this infrastructure, threat actors can stage, launch, and execute an operation. Threat actors may utilize these systems for various tasks, including Execution and Exfiltration. | |
| DE-0004 | Masquerading | Threat actors may gain access to a victim spacecraft by masquerading as an authorized entity. This can be done several ways, including through the manipulation of command headers, spoofing locations, or even leveraging Insider's access (i.e., Insider Threat) | |
| ID | Description |
| SV-IT-5 | Onboard control procedures (i.e., ATS/RTS) that execute a scripts/sets of commands |
| SV-SP-9 | On-orbit software updates/upgrades/patches/direct memory writes. If TT&C is compromised or MOC or even the developer's environment, the risk exists to do a variation of a supply chain attack where after it is in orbit you inject malicious code |
| SV-AC-1 | Attempting access to an access-controlled system resulting in unauthorized access |
| SV-MA-7 | Exploit ground system and use to maliciously to interact with the spacecraft |
| SV-AC-4 | Masquerading as an authorized entity in order to gain access/Insider Threat |
