AWS Identity and Access Management (IAM)
AWS Identity and Access Management (IAM) provides a secure way to oversee access to AWS services and resources. With IAM, you have the ability to create and manage users and groups within AWS, while setting permissions to either grant or restrict their access to various resources. This valuable service comes at no extra cost beyond what you may incur from the usage of other AWS services by your users. IAM allows users to manage access to AWS service APIs and specific resources, ensuring that control is maintained. Moreover, IAM lets you implement specific conditions to further refine user access, such as time of day restrictions, the user's IP address, the use of SSL, or the requirement for multi-factor authentication (MFA). To enhance the security of your AWS environment, you can utilize AWS MFA, which is an added security layer that works alongside standard username and password credentials. MFA necessitates that users demonstrate physical possession of either a hardware MFA token or a mobile device equipped for MFA by entering a valid code. By implementing these measures, you can significantly increase the security posture of your AWS resources, safeguarding them against unauthorized access.
