The Identity Conundrum: Enforcing Least Privilege Access At Scale

Overview

In the modern cybersecurity landscape identity isn’t a perimeter, it’s a highway. As organizations scale, that highway gets longer, wider and more complex. We’ve reached a point where non-human identities such as machine service accounts and AI rival or even outnumber actual human users in many organizations. This additional footprint and complexity, often combined with a lack of oversight makes it even more difficult to stop threat actors gaining a foothold.

To combat this, XM Cyber has announced major platform enhancements designed to tackle one of the most stubborn hurdles in security: identity and permissions sprawl. These updates empower organizations to enforce Least Privilege Access (LPA), effectively shrinking the attack surface before a threat actor can gain a foothold.

The Challenge: Complexity vs. Control

The principle of LPA is simple: give users only the access they need to do their jobs. Least privilege access is a well-established principle for maintaining effective security posture, but it can be a challenge for many organizations to achieve, as they struggle with the complexity of managing identities and access permissions at enterprise scale.

In a sprawling enterprise, this can mean thousands of identities across on-premises and multi-cloud environments, often with complex, intertwined relationships. As a result, security teams are often hesitant to revoke permissions for fear of breaking critical business operations.

Implementing Proactive Identity and Access Security Hygiene

XM Cyber already provides valuable insight for security and IAM teams, with actionable intelligence on Active Directory and cloud configurations, roles with excessive permissions, details on cached, leaked and reused local and domain credentials and the security posture of third-party identity security tools.

he upcoming capabilities take that intelligence a step further. In addition to preventing adversarial misuse of excessive permissions in the context of a validated attack path, identity and cloud security teams can now see if those permissions are actively in use. This makes it significantly faster for teams to assess if elevated permissions across Active Directory and cloud deployments are required and remove them if needed.

By bridging this gap between potential risk and actual usage, XM Cyber enables proactive identity and access security hygiene.

Key Platform Enhancements:

  • Active Directory Excessive Permissions: Active Directory entities are assessed to ascertain how frequently they are making use of their permissions. This makes it significantly easier for identity security practitioners to decide whether a specific permission level is required and provide necessary evidence to provision a fix, speeding time to reduce risk and close attack paths that exploit that permission.
  • Cloud Infrastructure Entitlement Management (CIEM): We’ve extended our cloud security capabilities to include complete, agentless visibility into user entitlements across multi-cloud environments. By analyzing effective access permissions and actual usage patterns, cloud security and DevSecOps teams can make informed decisions when cleaning up overly-permissive roles, boosting overall security posture and identity security hygiene.

Together, these capabilities provide critical context into how permissions are actually used across the enterprise – which is essential in modern environments where identities, roles and entitlements are continuously changing.

This additional insight, seamlessly combined with broad exposure discovery across credentials, human, machine and AI accounts, vulnerabilities, misconfigurations, exploits and more gives organizations a holistic view of exploitable risk across their hybrid environments – enabling better prioritization and driving faster remediation.

Getting Started

These powerful new capabilities will soon be available for all XM Cyber customers with the requisite licensing entitlements. Please contact your Account Manager if you would like more information.
