My main use case for Arctic Wolf Managed Detection and Response is detecting and responding to security threats. My job involves responding to the alerts that Arctic Wolf detects and managing their risks by either hardening and patching devices and endpoints, or by responding to an alert, investigating, and remediating incidents.
A recent situation where I used Arctic Wolf Managed Detection and Response to respond to a threat involved an alert indicating that a user's account may have been breached. I was able to investigate and confirm what was occurring after an incident where a user had multiple sign-in failures and eventually a malicious user was able to access their account.
Once I received the alert from Arctic Wolf Managed Detection and Response, the first thing I did to investigate and remediate the situation was to validate the alert by examining the logs and confirming the sign-in logs in Entra ID to determine that the user was indeed breached and that the malicious user was able to guess that user's password. After that confirmation, I immediately contained the user by disabling the account, resetting their password, and ensuring MFA was enabled.
