In today’s hybrid IT environments, where on-premises systems intertwine with cloud platforms like Microsoft Entra ID, cybersecurity risks are escalating at an alarming rate. On this episode of the CloudTweaks Podcast, host Steve Prentice is joined by Martin Cannard, VP of Product Strategy at Netwrix, to unravel the complexities of Privileged Access Management (PAM) and its critical role in safeguarding against modern cyber threats.
Why PAM Matters
Martin begins by defining Privileged Access Management as the process of securing, monitoring, and managing access to critical systems by users with elevated permissions. While PAM has evolved over two decades, from simple password checkouts to comprehensive session management, its importance in hybrid environments has never been greater. Misconfigured accounts, overly permissive access, and poor password hygiene create vulnerabilities that attackers readily exploit, often gaining access to both on-premises and cloud systems.
Threats in Hybrid IT
Martin provides real-world examples of how attackers leverage lateral movement, privilege escalation, and credential harvesting to compromise systems. He details methods like *pass-the-hash*, *pass-the-ticket*, and the emerging *pass-the-PRT (Primary Refresh Token)* attack, which bypasses MFA and conditional access controls. These tactics highlight how easily attackers can exploit gaps between on-prem Active Directory and cloud environments like Entra ID. Missteps like group nesting errors or improperly configured synchronization amplify these risks.
Emerging Threats and Vulnerabilities
The discussion also touches on supply chain risks, especially with third-party access to hybrid infrastructures. Contractors and vendors often introduce backdoor vulnerabilities through privileged accounts. Even as organizations gradually shift toward fully cloud-based environments, hybrid models will persist for years, keeping these risks relevant.
Practical Solutions: From Zero Standing Privilege to Just-in-Time Access
The episode emphasizes transformative solutions like Zero Standing Privilege (ZSP) and Just-in-Time Access (JIT), which reduce an organization’s attack surface by eliminating persistent privileges. Martin explains how these methods create ephemeral accounts that exist only when needed, preventing lateral movement and privilege misuse. For example, removing standing domain admin rights can significantly reduce risks without disrupting business operations.
How to Get Started
Martin advises organizations to focus on high-value, low-effort changes first, such as implementing privilege orchestration for domain administrators. Building confidence through quick wins and simple processes helps drive adoption across the organization. PAM strategies should extend beyond domain and global admins to local admins, applications, and databases, ensuring a consistent approach across all systems.
Key Takeaway
PAM is not just a tool but a mindset. As Martin aptly puts it, it’s far easier to deal with a problem by removing it, as opposed to simply managing it. By embracing simplicity and aligning PAM strategies with human behavior, organizations can build stronger defenses against ever-evolving cyber threats.
This episode is a must-listen for IT leaders, CISOs, and cybersecurity professionals looking to protect their hybrid environments from escalating risks. Whether you’re exploring PAM for the first time or refining an existing solution, Martin Cannard’s expert insights provide actionable strategies to mitigate threats and future-proof your infrastructure.
