Classification:attackTactic:[TA0003-persistence](https://attack.mitre.org/tactics/TA0003)Technique:[T1556-modify-authentication-process](https://attack.mitre.org/techniques/T1556) 
## Goal{% #goal %}

Detect when multi-factor authentication (MFA) is disabled for an Azure AD user.

## Strategy{% #strategy %}

This rule monitors the following Azure AD Audit Log event to detect when a user's MFA is disabled:

- `Disable Strong Authentication`

Disabling MFA makes an account more vulnerable to takeover. Attackers may attempt to disable MFA to gain access other user accounts or maintain persistence in an already-compromised account.
