Important elements of AWS security are the AWS_ACCESS_KEY and Secret Key, that enable users and apps to securely authenticate and access cloud resources. By serving as distinct identifiers, these credentials ensure strong authentication procedures and allow programmatic interactions with AWS services. Enforcing strict access rules and preserving the secrecy of these keys are essential to maintaining the security of AWS environments. Access credentials’ overall security posture has been enhanced by utilizing AWS’s security capacity, such as multi-factor authentication and key management services. Regular audits and monitoring guarantee compliance with security standards and laws by reducing the risks associated with illegal access attempts.
What are AWS Access key and Secret key?
- AWS_ACCESS_KEY: The AWS_ACCESS_KEY is a user-specific identifier that grants access to AWS resources. Think of it as a digital key that uniquely identifies an AWS user or application. When making API requests or utilizing the AWS Command Line Interface (CLI), this key serves as a secure means of authentication.
- SECRET_KEY: The Secret Key complements the AWS_ACCESS_KEY, adding a layer of security. While the AWS_ACCESS_KEY is shared openly, the secret key is kept confidential. Together, these keys establish a secure connection between the user or application and AWS services.
AWS offers a variety of security credentials created for different ways that users can access their cloud accounts. Users need to have a login and password to use the AWS Management Console. Additionally, particular credentials are needed for programmatic access.
There are two primary methods for getting access:
- Console Access
- Programmatic Access
Console Access
Being an IAM (Identity and Access Management) user or a root user are the only two primary methods for obtaining console access to AWS. Users establish credentials, which consist of an email address and password, for the root user when they set up an AWS account. With these credentials, the AWS account’s root user is the only one with complete access to all resources and permissions. On the other hand, IAM administrators or the root user construct each IAM user’s own set of credentials inside the AWS account. Logging in as an IAM user requires the password, an IAM username that is suitable, and the account alias or 12-digit AWS account ID. This limitation on access guarantees that
Programmatic Access
Programmatic access in Amazon Web Services (AWS) takes use of access credentials to allow automated interactions with cloud services. These credentials serve as authentication tokens that enable users and apps to communicate programmatically with AWS services. Typically, they include an AWS_ACCESS_KEY and a Secret Key. Among other things, programmatic access is frequently utilized for managing resources and provisioning, app setup, and AWS services integrating with software processes. If users wish to use programmatic access, they have to comply with AWS security best practices, which include setting up robust access controls, updating usernames and passwords frequently, and safely handling their access credentials. Among the various programs and services offered by the Amazon Web Services (AWS) platform is AWS Identity and Access Management (IAM), that provides easy control over permissions and access controls.
Managing access keys (AWS CLI)
Users can generate, look at, rotate, and delete access keys for IAM users directly from the command line by using the AWS Command Line Interface (CLI). Administrators can efficiently handle access keys across many IAM users or accounts using the use of commands like create-access-key and delete-access-key. This approach helps to enforce security best practices and maintain the integrity of AWS environments through providing flexibility, automation, and control over access to AWS resources.

Steps to Create AWS access key and secret key?
Here are the detail steps to create the aws access key and the secret keys.
Step 1: Log into your AWS account. Then, in the AWS management console, go to your profile.
Step 2: Then click on Security credentials. After this go to Access Keys and click on Create access Key.
Step 3: After this tick on I understand . Then on the bottom click on create access key.
Step 4: The Access key ID and the secret key is now created .The next step is to save the access key ID and the secret key . You can download it as .csv file or you can simply copy Access key ID and Secret key for further use.
Step 5: Then click Done on the bottom. After this a prompt will open , in the prompt click continue.
You have successfully created AWS Access key and Secrete key.
Creating access keys for the root user
Since there are security hazards, it shouldn’t be done to create access keys for the root user in AWS. Because the root account has full access to all AWS services and resources, attackers find it to be an attractive target. Creating IAM users with appropriate privileges and using their access keys for programmatic access is suggested instead. Better security controls, such the use of least privilege concepts and key rotation, have been rendered feasible by this method. Access keys for the root user can be generated via the IAM group under “Security Credentials,” however, if they are absolutely required for legacy systems or certain use cases. It is imperative to handle these keys extremely carefully, preserve them securely and only use them when they are absolutely necessary.
Best Practices For Managing AWS Access Keys
- Rotate Access Keys Regularly: Establish a key rotation policy that involves swapping out access keys on a regular basis—ideally, twice every 90 days. In the event that a key is compromised, this lowers the likelihood of unauthorized access.
- Use IAM Policies for Least Privilege: Use IAM policies to assign rights while keeping to the least privilege idea. Allow users and applications access to only the resources and activities required for their particular roles and tasks.
- Enable Multi-Factor Authentication (MFA): MFA must become required for IAM users in an effort to strengthen access key security. This ensures that access will continue to call for a second authentication factor even in the unlikely scenario that access keys are compromised.
- Monitor and Audit Access: To monitor and keep track of requests to API made on your AWS account—including those that need access keys—use AWS CloudTrail. Examine these logs on an ongoing basis for any illegal access attempts or suspicious activity.
- Secure Access Key Storage: Maintain your access keys safe and do not set them into configuration or code files. For safe access management of keys and rotation, take into account utilizing the AWS Secrets Manager or AWS Systems Manager Parameters Store.
Updating access keys
For IAM (Identity and Access Management) users, updating access keys involves generating new ones and deactivating the old ones in order to keep secure access to AWS resources. Using the AWS Management Console, AWS CLI (Command Line Interface), AWS SDKs (Software Development Kits), or API calls, administrators can programmatically change access keys. Generating a new access key pair, shifting the access key credentials in scripts or applications, and deactivating or deleting the previous access key pair are typical steps in this process. Updating access keys on frequently helps reduce the danger of compromised keys resulting in illegal access and keep the security of AWS environments.
Securing access keys
Here are the top three techniques to secure the access keys.
- Limit Access and Use IAM Policies: Utilize IAM policies to guarantee the least privilege and only grant access keys to groups that are absolutely required.
- Rotate Access Keys Regularly: Rotate your keys every 90 days to lessen your vulnerability in the event that you are compromised.
- Secure Storage and Enable MFA: Use tools like AWS Secrets Manager, stop hardcoding, and store keys securely. For additional safety, turn on Multi-Factor Authentication (MFA).
