Identity and Access Management (IAM) is a process that helps organizations secure their systems and data by controlling who has access to them and what they can do with that access. Effective IAM includes a number of best practices, such as:

Unique user IDs: Each user should have a unique ID that is used to identify them across all systems and applications.

Credentials: Users should be required to provide authentication credentials, such as a password or biometric data, in order to access systems and data.

User responsibility: Users should be made aware of their responsibilities when it comes to security, such as the need to keep their passwords secret and the importance of reporting suspicious activity.

Demographics refers to the statistical characteristics of a population, such as age, gender, income, etc. While demographic data may be collected and used for various purposes, it is not a recommended practice for effective IAM. Demographic data is not a reliable method of identification or authentication, and it is not used to provide access to systems and data.
