Simulating PAM Integration With SIEM: Privileged Access Alerting And Analysis Explained

This document explores how Privileged Access Management (PAM) integrates with Security Information and Event Management (SIEM) for real-time monitoring, correlation, and threat detection. The simulation includes attack scenarios using CyberArk, alongside logs from EDRs, Windows/Linux event logs, VPNs, and cloud platforms (AWS) to demonstrate SIEM alert correlation.

You Should Know:

1. PAM-SIEM Integration Setup

To simulate PAM-SIEM integration, follow these steps:

• Step 1: Configure CyberArk Log Forwarding

  CyberArk log forwarding to SIEM (Splunk/Syslog) 
  Set-CPMSyslogServer -ServerAddress "SIEM_IP" -Port 514 -Protocol UDP 
  

• Step 2: Ingest Windows Event Logs

  Forward Windows Security Logs to SIEM 
  wevtutil sl Security /e:true 
  

• Step 3: Linux Syslog Configuration

  Configure rsyslog to forward logs to SIEM 
  echo "auth. @SIEM_IP:514" | sudo tee -a /etc/rsyslog.conf 
  systemctl restart rsyslog 
  

2. SIEM Alert Correlation Rules

Example Splunk SPL for detecting suspicious privileged access:

index=cyberark OR index=windows EventCode=4624 Account_Name="admin" 
| stats count by Account_Name, src_ip 
| where count > 5 

3. Simulating Attack Scenarios

• Brute Force on Privileged Accounts

  Simulate brute force with Hydra 
  hydra -l admin -P passwords.txt ssh://TARGET_IP 
  

• Abusing Sudo Rights (Linux)

  Check sudo logs 
  sudo grep "sudo:" /var/log/auth.log 
  

• Detecting Unauthorized AWS CLI Access

  AWS CloudTrail monitoring 
  aws cloudtrail lookup-events --lookup-attributes AttributeKey=Username,AttributeValue="admin" 
  

4. Automated Response with SIEM

• Splunk Adaptive Response (Block IP)

  | blockip src_ip 
  

• Azure Sentinel Playbook (Disable User)

  Disable-AzureADUser -ObjectId "compromised_user" 
  

What Undercode Say:

PAM-SIEM integration is critical for detecting privilege escalation, lateral movement, and insider threats. Key takeaways:
– Monitor CyberArk sessions for anomalies.
– Correlate Windows Event ID 4672 (Admin Logon) with SIEM alerts.
– Use Linux auditd for tracking sudo commands (auditctl -a always,exit -F arch=b64 -S execve).
– Automate responses to reduce attacker dwell time.

Expected Output:

• SIEM Alerts: Unusual privileged logins, multiple failed access attempts.
• Log Sources: CyberArk, Windows Event Logs, Linux auth.log, AWS CloudTrail.
• Commands Used:

  Check failed SSH attempts 
  grep "Failed password" /var/log/auth.log 
  

  List privileged users in Windows 
  net localgroup administrators 
  

Prediction:

As cloud and hybrid environments grow, PAM-SIEM integration will evolve with AI-driven anomaly detection, reducing false positives and improving real-time threat response.
