What Is Least Privilege?

Least Privilege is a core identity and access management concept that every cybersecurity and GRC professional should understand.

What Is Least Privilege?

Least Privilege refers to the practices, processes, or technologies related to least privilege within the context of information security and risk management. Understanding least privilege helps organizations protect their systems, data, and operations from relevant threats.

How It Works

Why It Matters

Organizations that correctly implement least privilege reduce their exposure to cyber risk, improve regulatory compliance, and strengthen their overall security posture.
