Mitigating Azure PAM Risks in GCC: What UAE Banks Must Do Now

The Unseen Dangers of Azure PAM in the GCC

Azure Privileged Access Management (PAM) is a suite of controls designed to limit, monitor, and log access to critical resources. In the GCC, where regulatory bodies like NESA and the NCA ECC demand stringent audit trails, PAM is often the first line of defense against privilege abuse. But here's the thing: many banks and government entities deploy Azure PAM without fully grasping its default configuration, creating blind spots that sophisticated adversaries can exploit.

Azure PAM works by requiring just-in-time (JIT) access, automatically revoking privileges after a set period, and recording every privileged session. This technique reduces the attack surface by only granting access when it's needed, and for a limited time. However, misconfigurations, overly permissive role assignments, and lack of integration with existing identity governance tools can create a false sense of security.

A Real-World Example: The Abu Dhabi Telecom Provider

During a recent penetration test for a leading Abu Dhabi telecom provider, I discovered a glaring issue. The organization had enabled Azure PAM but hadn't enforced the "just-in-time" policy on any critical virtual machines. This meant that privileged users could remain logged in indefinitely, creating a perfect playground for attackers. When I attempted to use a stolen credential, the session persisted for 48 hours, giving the attacker ample time to pivot.

This scenario isn't isolated. I've seen a pattern emerge: vendors claim PAM is easy to set up, but the configuration is often left to the IT team's discretion, who may lack the depth to apply the nuanced controls that Azure offers.

Why UAE Banks Keep Failing Azure PAM Controls

1. Over-reliance on Default Settings

Most CISO teams assume that enabling Azure PAM automatically hardens the environment. In reality, default settings rarely align with NESA's strict audit requirements. For example, the default "Role-Based Access Control (RBAC) escalation" policy allows users to request elevated permissions without a mandatory approval workflow.

1. Fragmented Identity Ecosystem

Many GCC banks run a hybrid identity model, with on-prem AD and Azure AD. When Azure PAM is applied only to the cloud segment, privileged accounts that exist in the on-prem domain remain unprotected. Attackers can use a compromised on-prem credential to elevate privileges in Azure, bypassing PAM entirely.

1. Inadequate Session Recording

Azure PAM offers session recording, but many teams disable it to avoid storage costs. Without recording, a compromised privileged session leaves no forensic trail, making incident response much harder.

1. Lack of Integration with SIEM

PAM events are not automatically fed into the organization's SIEM. Consequently, security analysts miss real-time alerts for suspicious privileged activity, leading to delayed detection.

1. Insufficient Role Segregation

The "Security Admin" role is often granted to a handful of senior engineers. This role can modify PAM policies themselves, creating a circular problem where the very people who can bypass PAM controls are the ones supposed to enforce them.

How to Harden Azure PAM in a GCC Environment

Step 1: Enforce Just-In-Time (JIT) Access for All Critical Resources

To enforce JIT access, define a strict JIT window - 30 minutes for everyday tasks, 4 hours for high-risk operations. Automate approvals using Azure AD Conditional Access to require a manager's approval before elevating privileges. Regularly audit the JIT policy to ensure no resource is exempted without justification.

Step 2: Align PAM with NESA Compliance Requirements

To align PAM with NESA compliance requirements, ensure every privileged session is logged with user identity, timestamp, and action performed. Store logs for at least 24 months, as mandated by NESA. Integrate PAM logs into the NESA audit framework and schedule automated compliance reports.

Step 3: Integrate PAM Across On-Prem and Cloud Identities

To integrate PAM across on-prem and cloud identities, map on-prem privileged accounts to Azure AD identities, then apply PAM policies to those mapped accounts. Use Azure AD Connect to sync privileged group memberships and prevent orphaned privileged accounts that bypass PAM.

Step 4: Enable Session Recording and Anomaly Detection

To enable session recording and anomaly detection, turn on session recording for all privileged sessions. Implement AI-driven anomaly detection using Microsoft Sentinel or a third-party SIEM that can flag unusual session patterns.

Step 5: Harden Role Segregation and Least Privilege

To harden role segregation and least privilege, create distinct privileged roles - separate "PAM Admin," "Application Admin," and "Security Admin." Implement role-based approval workflows, requiring at least two independent approvals for any role elevation. Conduct a monthly review of role assignments, removing any that are no longer necessary.

Step 6: Integrate PAM with SIEM for Real-Time Alerts

To integrate PAM with SIEM for real-time alerts, configure Azure Monitor to forward PAM events to Sentinel. Set up alerts for failed privilege requests, prolonged sessions, and policy changes. Use playbooks for automated response, triggering a playbook that logs the user out and notifies the security team when a suspicious privileged session is detected.

A Real-World Attack Scenario: APT28 Targeting a UAE Bank

In 2023, a UAE bank fell victim to a phishing campaign spear-phishing for a senior IT director. The attacker obtained the director's credentials and used them to request elevated privileges via Azure PAM. Because the bank had not enforced JIT or required multi-factor approval, the attacker received immediate admin access to the core banking application.

The attacker then pivoted to the on-prem domain, exploiting an unpatched SMB vulnerability. With elevated privileges, the attacker exfiltrated customer data over a month before detection.

Key lessons from this attack: JIT and MFA are essential, even for trusted users. Phishing is still a highly effective vector, and regular security awareness training is crucial. Cross-domain visibility is critical, and Azure PAM alone cannot protect on-prem resources; integration is mandatory.

People Also Ask

What Are the Most Common Misconfigurations in Azure PAM?

The most frequent misconfigurations include leaving the "always on" policy enabled, disabling session recording, and granting blanket admin roles without approval workflows.

How Does Azure PAM Compare to Traditional PAM Solutions?

Azure PAM is tightly integrated with Azure AD, offering native JIT and session recording. Traditional PAM solutions often require separate appliances and may lack seamless integration with cloud workloads, leading to fragmented security postures.

Why Is Azure PAM Essential for NESA Compliance?

NESA mandates detailed audit trails for privileged access. Azure PAM automatically logs every privileged session, meeting the audit requirements and providing evidence during regulatory reviews.

Final Thoughts

Azure PAM is a powerful tool, but it's not a magic bullet. As a CISO in the GCC, you need to treat PAM as a living policy, not a one-time deployment. I've seen firsthand how a well-configured PAM system can prevent attacks, but a poorly configured one can leave you wide open. So, the next time you review your Azure PAM settings, ask yourself: are we really protected, or are we just checking boxes? The answer might surprise you.
