Alerts updated:
Detection name | Detection description | Devo table/Data source/Category | Changes made |
| Attackers may attempt to escalate privileges to a user account by adding it to a local security-enabled group. This could indicate privilege abuse or potentially malicious activity. |

| Detects multiple failed authentications from a single IP in Office365. |
| Updated mmcity operation |

| Detects the same session ID used from a new IP for the same user in a short period of time. |
| New Alert! |
| Detects when a single internal IP is scanning other internal IPs using different ports for each scan attempt. This is a low and slow technique intended to avoid triggering traditional port scan and port sweep alerts. |
| Field Naming Update |
| Adversaries may impair a system's ability to hibernate, reboot, or shut down in order to extend access to infected machines. When a computer enters a dormant state, some or all software and hardware may cease to operate which can disrupt malicious activity. |
