'Detects a successful logon by a privileged account from an ASN not logged in from in the last 14 days.
Monitor these logons to ensure they are legitimate and identify if there are any similar sign ins.'

Adversaries may manipulate accounts to maintain access to victim systems.
Account manipulation may consist of any action that preserves adversary access to a compromised account, such as modifying credentials or permission groups

Detects scenario where if a user is assigned the SeEnableDelegationPrivilege right in Active Directory it would allow control of other AD user objects.
'Detects a URL being added to an application where the domain is not one that is associated with the tenant.
The query uses domains seen in sign in logs to determine if the domain is associated with the tenant.
Applications associated with URLs not controlled by the organization can pose a security risk.

This should be monitored closely and all additions reviewed.'

Look for adding a user to Administrators in remote desktop users via PowerShell.
Intent:
- Use MTP capability to look for insider threat potential risk indicators
- Indicators would then serve as the building block for insider threat risk modeling in subsequent tools
Definition of Insider Threat:
"The potential for an individual who has or had authorized access to an organization's assets to use their access, either maliciously or unintentionally, to act in a way that could negatively affect the organization."
This collection of queries describes the different indicators that could be used to model and look for patterns suggesting an increased risk of an individual becoming a potential insider threat.
Note: no single indicator should be used as a lone determinant of insider threat activity, but should be part of an overall program to understand the increased risk to your organization's critical assets. This in turn is used to feed an investigation by a formal insider threat program to look at the context associated with the whole person to understand the implication of a set of indicators.
