As one of the leading cloud computing providers, Amazon Web Services (AWS) has established policies to ensure its users’ security, compliance, and privacy. AWS policies cover various topics, from acceptable use to billing policies, and users need to understand them. In this blog post, we’ll explore AWS policies, the different types of policies, and why they matter.
What are AWS Policies?
AWS policies are a set of rules and guidelines that users must follow when using AWS services. These policies ensure that users use AWS services safely and appropriately and help AWS maintain a secure and reliable computing environment.
Types of AWS Policies
Below are the available policy types in AWS, listed in order of frequency of use. For further information, please refer to the respective sections provided for each policy type.
Identity-Based Policies in AWS control access to resources based on the identity of the user or group. They grant or restrict access based on the user’s actions. They are critical for AWS security and compliance, managing access to AWS resources, and providing an audit trail of user activity.
Resource-Based Policies in AWS control access to resources based on the help itself. These policies are attached to resources to manage access to them. They grant or restrict access based on actions the user or service can perform. They are critical for AWS security and compliance, controlling access to AWS resources, and providing an audit trail of resource activity.
Permissions Boundaries in AWS define the maximum permissions granted to an IAM user or role. It limits their actions on AWS resources, ensuring they cannot perform unauthorized actions. It is helpful in scenarios where permissions must be granted to an external party or third-party application with a limited scope.
Organizations SCPs (Service Control Policies)
Service Control Policies (SCPs) in AWS manage permissions and security for multiple AWS accounts. SCPs are attached to an AWS Organization to set boundaries for what each account can access. They are a critical component of AWS security and compliance, allowing organizations to maintain control over their AWS environment and ensure that all accounts follow the same policies and regulations.
Access Control Lists (ACLs)
Access Control Lists (ACLs) in AWS manage access to S3 buckets and objects. ACLs define which AWS accounts or users can read or write to a specific bucket or object. They are critical to AWS security and compliance, allowing organizations to manage their S3 resources and prevent unauthorized access or data breaches.
Session Policies in AWS define the permissions granted to a user during an AWS session. They are temporary policies granting users permission for a specific duration or session. Session Policies provide an additional layer of security, ensuring users only have the necessary permissions to complete their tasks. They are critical for AWS security and compliance, allowing organizations to limit the scope of permissions granted to users and maintain control over their AWS environment.
Why Do AWS Policies Matter?
AWS policies are essential for maintaining the security and privacy of users’ data and infrastructure. These policies outline the appropriate use of AWS services and provide guidelines for users to follow to ensure their compliance with industry and regulatory standards.
AWS policies also provide a level of transparency to users. By reviewing AWS policies, users can understand their rights and obligations when using AWS services. Additionally, policies such as the Service Level Agreement (SLA) provide a guaranteed level of service and compensation if AWS fails to meet its uptime commitments.
AWS policies are a critical component of using AWS services. They guide users on proper use, security, compliance, privacy, and billing. Users should familiarize themselves with AWS policies to understand their obligations and rights when using AWS services. By following AWS policies, users can help ensure the safety and security of their data and infrastructure in the cloud.
