Amazon S3 Security
Amazon Simple Storage Service (Amazon S3) launched over 16 years ago and today houses over 200 trillion objects making it one of the most successful services provided by AWS. Organizations use Amazon S3 to build data lakes, run cloud-native applications, backup and restore critical data, and archive data at low cost. Amazon S3's popularity has made it the center pin of cloud computing. This popularity has opened the door to advanced threats such as malware, ransomware, viruses, worms, trojans, and more.
If you ingest files into Amazon S3 from third-party sources that can eventually enter an environment where they become executable, you're opening the door to malicious payloads. Learn how to protect your users, customers and partners from ransomware, viruses, trojans and more during this detailed and technical event - Antivirus For Amazon S3 Workshop: Malware Scanning For Application Workflows. This article includes links to register as well as what's being covered and who would benefit most from attending.
AWS celebrated 16 years since the launch of Amazon S3 with AWS Pi Day on March 14, 2022. Since the beginning of the year, some incredible announcements have been made including improvements to file integrity, the new Glacier Instant Retrieval storage class, general availability of AWS Backup, and much more. With over 200 trillion files being stored (that’s 29,000 files per person on earth) and more than 100 million requests per second for files, S3 is used now more than ever. However, there’s still one aspect of storage security that continues to be overlooked — the topic of antivirus scanning.
As a fast-growing learning management solution, MindEdge was receiving a growing number of questions from existing and potential customers about their security practices. MindEdge determined that the best route for elevating customer confidence was to achieve SOC 2 compliance. While preparing their roadmap for making their system and processes SOC 2 compliant, they found themselves in need of additional security controls to ensure that objects stored and shared from Amazon S3 buckets were scanned and clean from malware. The team identified three main requirements that needed to be met:
ADEC Innovations hosts an application on AWS that collects environmental data, charts, and assets from public sources and aggregates these resources as elements in a pdf report for environmental professionals. The reports are stored in Amazon S3 buckets and delivered to customers via automated email.
Occasionally, customers would report that the delivery of the file had been blocked by their firewall or that the local device’s endpoint solution warned the user of potential malicious code embedded in the report.
Workvivo is a workplace employee communication platform that allows organizations to keep their employees engaged and up to date with what their colleagues are doing. Like many solutions hosted on AWS, Workvivo utilizes Amazon S3 as the data store for ingesting and sharing files with its application users. Since employees using the platform can upload videos, images, documents, and other files, Workvivo realized there was a need to ensure that uploaded files are scanned for viruses and malware before they are shared with downstream application users.
According to a release from the U.S. Department of Justice, “Roughly $350 million in ransom was paid to malicious cyber actors in 2020, a more than 300% increase from the previous year”. With Amazon S3 buckets continuously being the storage medium for uploaded files by most organizations, the attack surface is only increasing when an S3 bucket is left misconfigured and storing infected files.
Poka's connected worker platform for manufacturers leverages Amazon to store a variety of training content and user uploaded files that are then shared with downstream users as part of the application workflow. In order to meet SOC 2 compliance requirements to prove that all files were scanned for potential malware before they were shared by their solution, Poka implemented a homegrown solution leveraging an open-source virus detection engine, AWS Lambdas, and Amazon EFS as the main components. As their customer base and the volume of data and files grew, their in-house solution required increasing maintenance time to meet their real time scanning requirements.
