Software Configuration
Implement configuration changes to software (other than the operating system) to mitigate security risks associated to how the software operates.
Techniques Addressed by Mitigation
| Domain | ID | Name | Use | |
|---|---|---|---|---|
| Enterprise | T1546 | .013 | Event Triggered Execution: PowerShell Profile |
Avoid PowerShell profiles if not needed. Use the -No Profile flag with when executing PowerShell scripts remotely to prevent local profiles and scripts from being executed. |
| Enterprise | T1562 | .006 | Impair Defenses: Indicator Blocking |
Consider automatically relaunching forwarding mechanisms at recurring intervals (ex: temporal, on-logon, etc.) as well as applying appropriate change management to firewall rules and other related system configurations. |
| Enterprise | T1559 | Inter-Process Communication |
Consider disabling embedded files in Office programs, such as OneNote, that do not work with Protected View.[4][5] |
|
| .002 | Dynamic Data Exchange |
Consider disabling embedded files in Office programs, such as OneNote, that do not work with Protected View.[4][5] |

| Enterprise | T1137 | Office Application Startup |
For the Office Test method, create the Registry key used to execute it and set the permissions to "Read Control" to prevent easy access to the key without administrator permissions or requiring Privilege Escalation. [1] |

| Enterprise | T1539 | Steal Web Session Cookie |
Configure browsers or tasks to regularly delete persistent cookies. |
|
| Enterprise | T1553 | Subvert Trust Controls |
HTTP Public Key Pinning (HPKP) is one method to mitigate potential man-in-the-middle situations where and adversary uses a mis-issued or fraudulent certificate to intercept encrypted communications by enforcing use of an expected certificate. [3] |
|
| .004 | Install Root Certificate |
HTTP Public Key Pinning (HPKP) is one method to mitigate potential man-in-the-middle situations where and adversary uses a mis-issued or fraudulent certificate to intercept encrypted communications by enforcing use of an expected certificate. [3] |

| Enterprise | T1535 | Unused/Unsupported Cloud Regions |
Cloud service providers may allow customers to deactivate unused regions.[2] |
|
| Enterprise | T1550 | .004 | Use Alternate Authentication Material: Web Session Cookie |
Configure browsers or tasks to regularly delete persistent cookies. |
