PAM (Privileged Access Management) is a security framework designed to manage, monitor, and control access to sensitive systems, data, and applications. It provides a centralized platform to manage privileged accounts, which are accounts with elevated permissions that can access critical resources.
How Does PAM Work?
- Privileged Account Discovery: PAM discovers and inventories all privileged accounts across the organization.
- Account Onboarding: PAM onboards privileged accounts, including creating, updating, and deleting them as needed.
- Access Request and Approval: Users request access, and PAM routes requests to approvers.
- Session Management: PAM establishes secure sessions and monitors them in real-time.
- Session Recording and Auditing: PAM records and audits all privileged sessions for accountability.
- Password Management: PAM securely stores, manages, and rotates privileged passwords.
Tools Used in PAM
- Privileged Account Management Software: CyberArk, BeyondTrust, Centrify
- Password Vaults: HashiCorp Vault, Thycotic Secret Server
- Session Management Tools: Bomgar, ObserveIT
- Auditing & Logging Tools: Splunk, ELK Stack
Benefits of PAM
✅ Improved Security – Reduces risk of misuse and cyberattacks.
✅ Compliance – Helps meet regulatory requirements (e.g., GDPR, HIPAA).
✅ Efficiency – Automates account management tasks.
✅ Visibility & Control – Real-time monitoring of privileged access.
Best Practices for Implementing PAM
🔹 Discover All Privileged Accounts – Audit existing accounts.
🔹 Use a Centralized PAM Platform – Single control point.
🔹 Apply Least Privilege Principle – Grant minimal necessary access.
🔹 Regularly Review PAM Policies – Ensure ongoing effectiveness.
You Should Know:
Linux Commands for PAM Implementation
1. Check PAM Modules:
ls /etc/pam.d/
Lists all PAM configuration files.
2. Secure SSH with PAM:
sudo nano /etc/pam.d/sshd
Add:
auth required pam_tally2.so deny=3 unlock_time=600
(Locks user after 3 failed attempts.)
3. Password Policy Enforcement:
sudo nano /etc/pam.d/common-password
Add:
password requisite pam_pwquality.so retry=3 minlen=12 difok=3
4. Session Logging:
sudo nano /etc/pam.d/system-auth
Add:
session required pam_exec.so /path/to/log_script.sh
Windows Commands for PAM
1. List Privileged Users:
net localgroup Administrators
2. Enable Audit Logging:
auditpol /set /subcategory:"User Account Management" /success:enable /failure:enable
3. Restrict Access with Group Policy:
gpedit.msc
Navigate to:
`Computer Configuration → Windows Settings → Security Settings → Local Policies → User Rights Assignment`
4. Rotate Passwords via PowerShell:
Set-ADAccountPassword -Identity "AdminUser" -Reset -NewPassword (ConvertTo-SecureString "NewP@ssw0rd!" -AsPlainText -Force)
Automated PAM Script Example (Bash)
[sh]
!/bin/bash
Rotate passwords for privileged accounts
for user in $(cat /etc/privileged_users.list); do
new_pass=$(openssl rand -base64 16)
echo “$user:$new_pass” | chpasswd
echo “Rotated password for $user at $(date)” >> /var/log/pam_rotation.log
done
[/sh]
What Undercode Say
PAM is critical for securing high-level access in enterprises. Without it, organizations face risks like insider threats, credential theft, and compliance violations. Implementing least privilege, session monitoring, and automated password rotation significantly reduces attack surfaces.
🔐 Key Takeaways:
- Always log and audit privileged sessions (
pam_exec, Splunk). - Enforce strict password policies (
pam_pwquality, Active Directory). - Automate where possible (Bash/PowerShell scripts).
Expected Output:
A structured PAM deployment with:
✔ Discovered privileged accounts
✔ Centralized access controls
✔ Real-time session monitoring
✔ Automated password management
✔ Compliance-aligned auditing
