 | `x_mitre_platforms` | string[] | All techniques | List of platforms that apply to the technique. |
 | `x_mitre_data_sources` | string[] | Enterprise and ICS domains | Sources of information that may be used to identify the action or result of the action being performed. |
 | `x_mitre_is_subtechnique` | boolean | Enterprise domain | If true, this `attack-pattern` is a sub-technique. See [sub-techniques](#sub-techniques). |
-| `x_mitre_system_requirements` | string | Enterprise domain | Additional information on requirements the adversary needs to meet or about the state of the system (software, patch level, etc.) that may be required for the technique to work. |

 Techniques map into tactics by use of their `kill_chain_phases` property. Where the `kill_chain_name` is `mitre-attack`, `mitre-mobile-attack`, or `mitre-ics-attack` (for enterprise, mobile, and ics domains respectively), the `phase_name` corresponds to the `x_mitre_shortname` property of an `x-mitre-tactic` object.
