8 Considerations for CyberArk PAM Architecture best practice

Core Components of CyberArk PAM Architecture

A well-structured CyberArk PAM architecture includes the following essential components:

• Password Vault Web Access (PVWA): The primary interface for users to request credentials and manage privileged accounts.
• Privileged Session Manager (PSM): Provides secure, monitored access to privileged accounts, ensuring session recording and auditing.
• Digital Vault: The highly secure repository where sensitive credentials, passwords, and session logs are stored.
• Central Policy Manager (CPM): Manages the lifecycle of privileged credentials by automatically rotating passwords according to predefined policies.
• Directory Services Integration: Allows for seamless integration with Active Directory (AD) to enforce authentication and authorization policies.

Ensuring High Availability in CyberArk PAM Architecture

To ensure continuous availability of CyberArk PAM architecture, it is important to set up a fault-tolerant and redundant system:

• Multiple PVWA Instances: Deploy multiple instances of PVWA behind a load balancer to distribute traffic and ensure high availability.
• Vault Disaster Recovery: While the Vault itself runs in a single-instance mode, configuring a Disaster Recovery (DR) Vault is essential for business continuity.
• Redundant PVWA and PSM Servers: Multiple instances of PVWA and PSM should be deployed to avoid a single point of failure and ensure uninterrupted access to privileged account management and session monitoring.
• Load Balancing: Implement load balancers to manage traffic between the multiple instances of PVWA, and PSM, ensuring optimized performance and failover capabilities.

Network Segmentation and Security in CyberArk PAM Architecture

Segregating network zones and applying strict access controls are fundamental for securing a CyberArk PAM architecture:

• Dedicated Vault Zone: The Vault should be isolated within a highly secure network zone with limited access only from key components like CPM, PSM, and PVWA.
• DMZ for Remote Access: If external users require access, deploy a PVWA instance in a DMZ zone and ensure all communication is encrypted with SSL to safeguard sensitive information.
• No Direct Access to the Vault: End-users should not have direct access to the Vault. All interactions should occur through secure channels like PVWA or PSM to maintain a high level of security.

Encryption and Server Hardening in CyberArk PAM Architecture

Strong encryption and system hardening are crucial for the security of CyberArk PAM architecture:

• TLS Encryption: Ensure that all communications between CyberArk components (PVWA, CPM, PSM) and between users and the Vault are encrypted using TLS to protect sensitive data.
• Vault Encryption: The Vault’s data should be encrypted with rotating encryption keys to ensure the highest level of security for stored credentials and recordings.
• Harden Servers: Perform system hardening on all servers, applying the latest security patches, disabling unnecessary services, and restricting server access to authorized personnel only.

Privileged Access Control in CyberArk PAM Architecture

Maintaining strict control over privileged access in a CyberArk PAM architecture is essential to minimizing the risk of misuse or compromise:

• Role-Based Access Control (RBAC): Assign access based on the principle of least privilege, ensuring users only have the permissions they need to perform their specific tasks.
• Separation of Duties: Implement role separation so that different teams or individuals handle different aspects of PAM, such as password management, session monitoring, and auditing.

Session Monitoring and Auditing in CyberArk PAM Architecture

One of the key benefits of a CyberArk PAM architecture is the ability to monitor and record privileged sessions:

• Privileged Session Manager (PSM): PSM isolates privileged sessions and provides the ability to record and audit those sessions. This enhances security by allowing for monitoring without exposing sensitive credentials.
• SIEM Integration: Integrating CyberArk with a Security Information and Event Management (SIEM) solution allows organizations to centralize alerts and analyze suspicious activities for immediate action.

Scalability in CyberArk PAM Architecture

As organizations grow, the CyberArk PAM architecture needs to scale efficiently:

• Horizontal Scaling: Deploy additional PVWA, and PSM instances to accommodate increased demand. CyberArk’s architecture is designed to scale horizontally, allowing for seamless growth as more privileged accounts and sessions need to be managed.
• Hybrid Deployments: For organizations with cloud and on-prem environments, consider hybrid deployments that allow the CyberArk PAM architecture to manage privileged access across multiple platforms.

Conclusion

Building a secure and scalable CyberArk PAM architecture is crucial for protecting privileged access and sensitive data. By following best practices like deploying redundant components, securing network zones, applying encryption, and monitoring privileged sessions, organizations can ensure that their PAM deployment is resilient and aligned with security objectives.
