Privilege escalation in OT and cloud: are standing privileges the problem?

TL;DR: Privilege escalation is increasingly driven by standing access, misconfigurations and credential abuse across IT, OT and cloud, according to Xage Security, and the article links that pattern to attacks that can reach physical systems, not just data. Eliminating persistent elevated access is the control boundary that matters most.

Editorial analysis by NHI Mgmt Group, based on content published by Xage Security: “Privilege Escalation Attacks: How to Stop Them With Zero Trust PAM”.

By the numbers:

• During Microsoft’s June 2024 Patch Tuesday, 49 vulnerabilities were addressed, with 49% classified as privilege escalation vulnerabilities.
• In August 2024, Microsoft disclosed updates for 85 vulnerabilities, with privilege escalation making up 37%.

Key questions

Q: What fails when privileged access stays permanently enabled?

A: Standing privileged access creates a long abuse window, weakens accountability, and makes audit evidence stale before anyone reviews it.

Q: When does privilege escalation become an operational resilience problem?

A: It becomes an operational resilience problem when elevated access can reach industrial systems, identity providers or cloud administration planes that support real business processes.

Q: What do security teams get wrong when they manage privileged cloud access with on-premises thinking?

A: A common mistake is treating cloud access like a fixed network problem instead of an identity problem.

Practitioner guidance

• Eliminate standing privileged access Inventory admin, contractor, service and support accounts that can still perform privileged actions outside a live task.
• Map OT privilege paths to business-critical assets Identify where legacy OT systems, identity providers and cloud control planes share the same elevation routes.
• Tighten third-party and contractor access lifecycles Require explicit expiry, offboarding and session-scoped access for vendors and temporary operators.

Bottom line: Standing privilege is the enabling condition that lets a limited compromise become broader administrative control across IT, OT and cloud.
