Identity and Access Management (IAM), least privilege, MFA.

• Validating the identities of employees and documenting access roles are essential to maintaining the organization's physical and digital security. For example, as a security analyst, you may be tasked with setting up employees' keycard access to buildings.
• The identity and access management (IAM) domain focuses on keeping data secure. It does this by ensuring user identities are trusted and authenticated and that access to physical and logical assets is authorized. This helps prevent unauthorized users, while allowing authorized users to perform their tasks.
• Essentially, IAM uses what is referred to as the principle of least privilege, which is the concept of granting only the minimal access and authorization required to complete a task.
