Eligibility

Eligibility in cybersecurity and Identity and Access Management (IAM) defines an entity's qualification or potential to receive specific access to resources, systems, or privileges within an organization. It represents a prerequisite status — the theoretical capacity to be granted access — rather than the permissions currently held. Eligibility criteria are established through policy frameworks leveraging models such as Role-Based Access Control (RBAC) or Attribute-Based Access Control (ABAC), taking into account factors like job function, organizational affiliation, security clearances, project roles, and regulatory requirements.

Managing eligibility is a dynamic and continuous process throughout the identity lifecycle. As an entity's status, responsibilities, or affiliations change, their eligibility must be reassessed to ensure alignment with the principle of least privilege, minimizing potential attack surfaces. This ongoing governance is essential for enforcing compliance, mitigating unauthorized access risks, and safeguarding sensitive information — ultimately strengthening an organization's overall security posture.
