What is ICAM?
Identity, Credential, and Access Management is a foundational security framework of policies, processes, and technologies.
The three pillars
Think of ICAM as the digital equivalent of a facility's security guard, a keycard, and door locks, all working together to manage and secure digital identities and control user access to critical resources.
WHO
Identity Management
The process of establishing and managing a unique digital representation for each individual or device, creating a single authoritative source of truth for the entire identity lifecycle from creation to deletion.
HOW YOU PROVE IT
Credential Management
The use of an object or piece of information to verify an identity. This includes something you know (password), something you have (CAC/PIV card), or something you are (fingerprint), with multi-factor authentication providing additional assurance.
WHAT CAN YOU DO
Access Management
The determination of which specific resources a user is allowed to use after their identity has been authenticated. See how least privilege guides access decisions.
