Why is the principle of least privilege important in IAM policies?

It means giving users only the permissions they need, reducing the risk of accidental or malicious data exposure or changes.

advanced

Can IAM policies be used to control access to specific items in a DynamoDB table?

Yes, IAM policies can include conditions to restrict access to specific items or attributes, providing fine-grained data protection.

What does an IAM policy primarily control?

A The physical location of AWS servers

B The cost of AWS services

C Who can access AWS resources and what actions they can perform

D The speed of data transfer

IAM policies define permissions for users and roles to access AWS resources.

If an IAM policy denies access to a DynamoDB table, what happens?

A The user is promoted to admin

B Access is granted anyway

C The table is deleted

D Access is blocked for the denied actions

Deny rules in IAM policies prevent users from performing specific actions.

What is the principle of least privilege in IAM policies?

A Giving users all permissions

B Giving users only the permissions they need

C Giving users no permissions

D Giving users random permissions

Least privilege limits permissions to reduce security risks.

Can IAM policies restrict access to specific items in a DynamoDB table?

A Yes, using conditions in the policy

B No, IAM policies only control whole tables

C Only if the table is encrypted

D Only if the user is an admin

IAM policies can include fine-grained conditions to restrict access.

Why are IAM policies important for protecting data?

A They control who can see or change data

B They speed up data queries

C They backup data automatically

D They encrypt data on disk

IAM policies manage permissions to protect data from unauthorized access.

Explain how IAM policies help protect data in DynamoDB.

Think about who can do what with the data.

Describe the principle of least privilege and why it matters in IAM policies.

Less is more when it comes to permissions.
