What is PAM? Understanding Privileged Access Management

By /

Listen to this Post

Privileged Access Management (PAM) is a critical cybersecurity 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 sensitive resources. PAM is essential for reducing the risk of cyberattacks, ensuring compliance, and improving operational efficiency.

How Does PAM Work?

  1. Privileged Account Discovery: PAM discovers and inventories all privileged accounts across the organization.
  2. Account Onboarding: PAM onboards privileged accounts, which involves creating, updating, and deleting accounts as needed.
  3. Access Request and Approval: Users request access to privileged accounts, and PAM routes the request to designated approvers for approval.
  4. Session Management: PAM establishes a secure session for the user to access the privileged account and monitors the session in real-time.
  5. Session Recording and Auditing: PAM records and audits all privileged sessions, providing a detailed record of all activities.
  6. Password Management: PAM securely stores and manages privileged account passwords, rotating them regularly to enhance security.

Tools Used in PAM

1. Privileged Account Management Software:

  • Examples: CyberArk, BeyondTrust, Centrify.
  • These tools provide a centralized platform to manage privileged accounts.

2. Password Vaults:

  • Examples: HashiCorp’s Vault, Thycotic’s Secret Server.
  • These secure storage solutions protect privileged account passwords.

3. Session Management Tools:

  • Examples: Bomgar, ObserveIT.
  • These tools establish and monitor secure sessions for privileged access.

4. Auditing and Logging Tools:

  • Examples: Splunk, ELK Stack.
  • These tools provide detailed auditing and logging capabilities for privileged access.

Benefits of PAM

  1. Improved Security: Reduces the risk of privileged account misuse and cyberattacks.
  2. Compliance: Helps organizations meet regulatory requirements and compliance standards.
  3. Increased Efficiency: Automates privileged account management tasks, reducing manual effort.
  4. Better Visibility and Control: Provides real-time monitoring and control over privileged access.

Best Practices for Implementing PAM

  1. Conduct a Privileged Account Discovery: Identify and inventory all privileged accounts across the organization.
  2. Implement a Centralized PAM Platform: Use a centralized PAM platform to manage and monitor privileged access.
  3. Establish a Least Privilege Model: Grant users only the privileges they need to perform their job functions.
  4. Regularly Review and Update PAM Policies: Ensure policies remain effective and aligned with organizational needs.

You Should Know: Practical Steps and Commands for PAM Implementation

1. Discover Privileged Accounts on Linux:

Use the following command to list users with sudo privileges:

grep -Po '^sudo.+:\K.*$' /etc/group

2. Rotate Passwords Automatically:

Use a script to rotate passwords for privileged accounts:

#!/bin/bash
for user in $(grep -Po '^sudo.+:\K.*$' /etc/group); do
echo "Rotating password for $user"
echo "$user:$(openssl rand -base64 12)" | chpasswd
done

3. Monitor Sessions with `auditd`:

Enable session monitoring on Linux using `auditd`:

sudo apt-get install auditd
sudo auditctl -w /etc/shadow -p wa -k privileged-access

4. Windows Command for Privileged Account Discovery:

Use PowerShell to list users in the Administrators group:

Get-LocalGroupMember -Group "Administrators"

5. Secure Password Storage with HashiCorp Vault:

Install and configure HashiCorp Vault for secure password management:

wget https://releases.hashicorp.com/vault/1.12.0/vault_1.12.0_linux_amd64.zip
unzip vault_1.12.0_linux_amd64.zip
sudo mv vault /usr/local/bin/
vault server -dev

What Undercode Say

Privileged Access Management (PAM) is a cornerstone of modern cybersecurity strategies. By implementing PAM, organizations can significantly reduce the risk of data breaches, ensure compliance with regulatory standards, and streamline access management processes. The use of tools like CyberArk, HashiCorp Vault, and Splunk, combined with best practices such as least privilege and regular policy reviews, ensures a robust security posture. Practical steps like automating password rotation, monitoring sessions, and discovering privileged accounts are essential for maintaining a secure environment.

Expected Output:

1. Linux Commands:

  • Discover sudo users: `grep -Po ‘^sudo.+:\K.*$’ /etc/group`
  • Rotate passwords: Custom script using `chpasswd`
  • Monitor sessions: `auditctl -w /etc/shadow -p wa -k privileged-access`

2. Windows Commands:

  • List administrators: `Get-LocalGroupMember -Group “Administrators”`

3. Tools:

  • CyberArk, BeyondTrust, HashiCorp Vault, Splunk

4. Best Practices:

  • Least privilege model, regular policy reviews, centralized PAM platform.

By following these steps and leveraging the right tools, organizations can effectively implement PAM and safeguard their critical assets.
