We’ve shared some critical issues to consider when you’re thinking about using S3, as well as tips for creating smart policies to manage your S3 buckets. Setting Up Smart S3 Bucket PoliciesĪmazon S3 is a powerful resource for applications that need storage on the internet.

CloudTrail captures a subset of API calls, including calls from the S3 console and code calls to the S3 APIs. You can enable CloudTrail data events for all your buckets or for a list of specific buckets. To detect suspicious behavior or spot security incidents, your organization should continuously monitor and audit user activities related to S3 buckets. MonitoringĪudit logging is an important element of your organization’s data security.

With S3 Lifecycle configuration rules, you can tell Amazon S3 to transition objects to less-expensive storage classes, or archive or delete them. You can customize your data retention approach and control storage costs by using object versioning with S3 Lifecycle. Note, versioning impacts S3 usage: S3 charges are based on storage, requests and data retrievals, data transfer, and data management. As a side benefit, versioning helps with NIST, PCI-DSS and GDPR compliance. If you delete an object, S3 inserts a delete marker. When you upload an object with the same name, S3 stores a new version of the object. When you enable versioning, S3 keeps multiple versions of each object in the bucket. It protects you from data loss from application issues or human error. If you ever need to go back in time in relation to file changes, you should ensure that your S3 buckets have versioning enabled. It’s also best to enforce encryption of data in transit using HTTPS (TLS) to block eavesdropping or network traffic manipulation. From the client side, you can encrypt data before uploading data to S3. For server-side encryption, S3 can encrypt your object before saving it and decrypt it when a user downloads the objects. IAM roles supply temporary permissions for applications to make calls to AWS resources.

Using a role eliminates distributing long-term credentials (such as a user name and password or access keys). It’s best to use an IAM role to manage temporary credentials for applications or services that access S3. Least privilege access is fundamental to reducing your security risks. You should only grant permissions required to perform specific tasks. That is, you should ensure that your S3 bucket is not public unless you explicitly need it to be. While some of your S3 buckets may need to be publicly accessible, most S3 buckets should have restricted access. It’s best to use names that are relevant to you or your organization. Names must be between 3 and 63 characters long, consist only of lowercase letters, numbers, dots, and hyphens, and begin and end with a letter or number. Once created, you can’t change the name or Region. When you create a bucket, you choose a name and its AWS Region.

You can also use the AWS Policy Generator to define a bucket policy for your buckets.īest Practices for Bucket Policies to Secure AWS S3 Buckets Bucket Naming

You can add or update a bucket policy using the Amazon S3 console. Bucket policies are an Identity and Access Management (IAM) mechanism for controlling access to resources. As a bucket owner, you are the one who applies a policy to a bucket. They are critical in securing your S3 buckets against unauthorized access and attacks. Permissions apply to all objects in the selected bucket. As an S3 user, your responsibility is to manage access to your data by assigning permissions and access levels.ĪWS S3 bucket policies allow you to grant access to a bucket and the objects (files) it contains. It means that AWS is responsible for protecting the infrastructure that runs Amazon S3. Hopefully you are already familiar with the Shared Responsibility Model. And in early August, a misconfigured Amazon S3 bucket at SeniorAdvisor exposed details of over 3 million senior citizens, including individuals’ names, numbers, and email addresses. The hackers modified a copy of Twilio’s JavaScript SDK that they share with customers. In May, Twilio, a large cloud communication platform as a service company, allowed a bad actor to gain read and write access to a misconfigured AWS S3 bucket. Over 200,000 images of ID scans were exposed. In February, Premier Diagnostics, a Utah COVID-19 testing service, leaked patient data records through two publicly available AWS S3 buckets that lacked any form of password protection or authentication. The key to success is setting up smart S3 bucket policies that are beneficial to intended users but protected from prying eyes.ĪWS S3 buckets, however, were in the 2021 headlines too many times for not good reasons. S3 is a scalable, reliable, and secure solution. Amazon S3 (Simple Storage Service) is a powerful resource for applications that need storage on the internet.
