Monitoring credential access in Active Directory (AD) is critical for detecting unauthorized activity. Kaido Järvemets’ latest blueprint details how to track Local Administrator Password Solution (LAPS) events using Microsoft Sentinel, ensuring defenders can trace who accessed passwords, when, and from where.
Key Steps for LAPS Monitoring with Sentinel
1. Enable Event ID 4662 Auditing
- Configure Group Policy to audit
AD DS > Security > Audit Directory Service Access. - PowerShell command to verify auditing:
Get-GPOReport -Guid (Get-GPO -Name "Default Domain Policy").Id -ReportType Html -Path "C:\AuditReport.html"
2. Forward Security Logs to Sentinel
- Use Azure Monitor Agent (AMA) to collect logs from Domain Controllers.
- Install AMA via ARM template or CLI:
az deployment group create --resource-group "YourRG" --template-file "AMA_Deploy.json"
3. Create a Custom Sentinel Analytics Rule
- KQL query to detect LAPS access attempts:
SecurityEvent | where EventID == 4662 | where ObjectName contains "ms-Mcs-AdmPwd" | project TimeGenerated, AccountName, Computer, IPAddress
4. Automate Alerts & Incident Response
- Set up Sentinel Playbooks to trigger Teams/SMS alerts.
You Should Know: Critical Commands & Scripts
- Check LAPS Password Expiry (Windows):
Get-AdmPwdPassword -ComputerName "TargetPC" | fl<br />
- List LAPS Permissions (PowerShell):
Find-AdmPwdExtendedRights -Identity "OU=Servers,DC=domain,DC=com" | Format-Table
- Linux Sysadmins (Audit LAPS via LDAP):
ldapsearch -H ldap://dc.domain.com -D "[email protected]" -W -b "dc=domain,dc=com" "(ms-Mcs-AdmPwd=)"
What Undercode Say
LAPS is a prime target for attackers moving laterally. By integrating Event ID 4662 with Sentinel, defenders gain real-time visibility into credential access. For deeper protection:
– Restrict LAPS permissions using Set-AdmPwdReadPasswordPermission.
– Deploy deceptive LAPS honey passwords to trap attackers.
– Cross-validate logs with `Sysmon Event ID 10` (Process Access).
Expected Output: A Sentinel dashboard showing LAPS access attempts, correlated with user/IP data, and automated alerts for anomalous behavior.
Prediction
As attackers increasingly exploit credential mismanagement, automated LAPS monitoring will become a baseline requirement for Zero Trust architectures. Expect Microsoft to enhance Sentinel’s native LAPS detection capabilities in 2024.
