In the cloud, it’s called least privileged access and refers to authorization policies that give authenticated principals only the access they need to perform a specific task. You’ll need to ensure that any roles you define have only the minimum access necessary to ensure the job can get done, limiting potential damage should a user’s account be breached. IAM provides the infrastructure necessary to control authentication and authorization for your account using role-based access. During transport, the HTTPS protocol ensures data is encrypted end to end.ĪWS security is based on AWS Identity and Access Management (IAM) policies. Encrypting the bucket will ensure that anyone getting their hands on the data will need a key (password) to decrypt it. On the server-side, Amazon S3 buckets support encryption, but it must be turned on. If you only have one bucket, this might not be complicated, but if buckets are being created dynamically, monitoring and controlling encryption might not be taking place the way you think it is. You’ll want to ensure that your Amazon S3 buckets are encrypted both on the server and during transport. Amazon Macie is also a great AWS tool that extends configuration monitoring by using machine learning to continuously monitor your Amazon S3 storage accounts' patterns of access. The available AWS Config service compares your configurations to your desired state and sends out notifications if something drifts out of compliance. So, when securing cloud resources, it’s important to focus on setting up and monitoring a configuration. But locking down these permissions can be complicated. Let’s take a look at five critical areas that newcomers, in particular, should pay attention to when migrating to the cloud.Īmazon S3 buckets have fine-grain permissions, and most users and applications accessing them need only a small subset to accomplish their tasks. These could be anything from a social engineering attack to a simple mistake that leaves data open and discoverable to anyone who notices. While cloud providers maintain highly secure cloud environments such as Amazon Simple Storage Service (Amazon S3), the cloud represents a new potential for security incidents. Of course, cloud storage is a big part of the migration equation due to its many advantages, including scalability, high availability, geographic distribution and potential cost savings. Companies continue to migrate to cloud-hosted infrastructure, applications, microservices and backend services worldwide.
