Which of the following actions helps improve security in AWS?

Rotating access keys regularly is a security best practice. If an access key is compromised, its exposure is limited to the period between rotations, reducing the potential impact. This practice makes it harder for attackers to maintain long-term access. Enabling programmatic access for all IAM users is a security risk as it increases the attack surface. Programmatic access should only be granted when necessary. Using IAM users instead of IAM roles to delegate permissions is less secure because roles provide temporary credentials and eliminate the need to share long-term access keys. Using inline policies instead of customer managed policies can lead to less consistent and harder-to-manage permissions, potentially increasing security vulnerabilities.
