These logs contain information about the requester, the target bucket, the response and other details about the request.
S3 BUCKETS FREE
Server access logs are free to create, though you will have to pay for the S3 storage space. (Thankfully, you can also enable these options on existing buckets.) AWS will store these logs in another S3 bucket, so the target bucket for these logs should be very secure.
When you create a bucket, you have the option of enabling server access logging and CloudTrail activity logging. Names like acme-paychecks-2020 or widgetco-resumes might invite unauthorized access attempts.Īn essential part of securing your S3 bucket is knowing who has access to it and what they’re doing with that access. You’ll want a name that is meaningful but doesn’t advertise the contents of your bucket to the world. Your name cannot already be in use, it must consist of lowercase letters, numbers, periods, and/or hyphens, and it must be between 3 and 63 characters long. Your S3 bucket needs to have a unique and DNS-compliant name. Is S3 the Right Place For Your Data?īefore you create an S3 bucket, you should ask the following questions: Does the information that you plan to store in S3 need to be held in S3, and is it subject to any regulatory guidelines? Personal, medical and financial information requires extra scrutiny, so S3 might not be the right place for it. Let’s take a look at the process of creating and managing an S3 bucket, as well as the security implications of each step.
S3 BUCKETS HOW TO
We’ll also explain how to monitor your S3 buckets and AWS configuration to ensure that you don’t become another cautionary tale from the land of breached buckets.
In this article, we will walk you through the process of securing your S3 buckets step by step. A simple mistake can lead to a misconfigured bucket, which can leave your data exposed and vulnerable. It isn’t complicated or difficult to protect AWS S3 buckets, which might actually be the reason why it’s often overlooked or neglected. If you haven’t, a simple Google search will return a troubling list of breaches ranging from small companies and large corporations to state and federal governments. Unfortunately, you’ve probably heard of at least one critical data leak that was due to an unsecured S3 bucket. Amazon Web Services (AWS) Simple Storage Service (S3) provides an easy option for storing documents, data and other information in the cloud.
