4 Specifically, this paper describes AWS physical and operational Security processes for the network and server infrastructure under the management of AWS. ArchivedAmazon Web Services Amazon Web Services: Overview of Security Processes Page 1 Introduction Amazon Web Services (AWS) delivers a scalable cloud computing platform with high availability and dependability, providing the tools that enable customers to run a wide range of applications. Helping to protect the confidentiality, integrity, and availability of our customers systems and data is of the utmost importance to AWS, as is maintaining customer trust and confidence.

5 Shared Security Responsibility Model Before covering the details of how AWS secures its resources, it is important to understand how Security in the cloud is slightly different than Security in your on-premises data centers. When you move computer systems and data to the cloud, Security responsibilities become shared between you and your cloud service provider. In this case, AWS is responsible for securing the underlying infrastructure that supports the cloud, and you re responsible for anything you put on the cloud or connect to the cloud. This shared Security responsibility model can reduce your operational burden in many ways, and in some cases may even improve your default Security posture without additional action on your part.

6 Figure 1: AWS shared Security responsibility model The amount of Security configuration work you have to do varies depending on which services you select and how sensitive your data is. However, there are certain Security ArchivedAmazon Web Services Amazon Web Services: Overview of Security Processes Page 2 features such as individual user accounts and credentials, SSL/TLS for data transmissions, and user activity logging that you should configure no matter which AWS service you use. For more information about these Security features, see the AWS Account Security Features section.

7 AWS Security Responsibilities Amazon Web Services is responsible for protecting the global infrastructure that runs all of the services offered in the AWS Cloud. This infrastructure comprises the hardware, software, networking, and facilities that run AWS services. Protecting this infrastructure is the number one priority of AWS. Although, you can t visit our data centers or offices to see this protection firsthand, we provide several reports from third-party auditors who have verified our compliance with a variety of computer Security standards and regulations.

8 For more information, visit AWS Compliance. Note that in addition to protecting this global infrastructure, AWS is responsible for the Security configuration of its products that are considered managed services. Examples of these types of services include Amazon DynamoDB, Amazon RDS, Amazon Redshift, Amazon EMR, Amazon WorkSpaces, and several other services. These services provide the scalability and flexibility of cloud-based resources with the additional benefit of being managed. For these services, AWS handles basic Security tasks like guest operating system (OS) and database patching, firewall configuration, and disaster recovery.

9 For most of these managed services, all you have to do is configure logical access controls for the resources and protect your account credentials. A few of them may require additional tasks, such as setting up database user accounts, but overall the Security configuration work is performed by the service. Customer Security Responsibilities With the AWS cloud, you can provision virtual servers, storage, databases, and desktops in minutes instead of weeks. You can also use cloud-based analytics and workflow tools to process your data as you need it, and then store it in your own data centers or in the cloud.

10 The AWS services that you use determine how much configuration work you have to perform as part of your Security responsibilities. AWS products that fall into the well-understood category of Infrastructure-as-a-Service (IaaS) such as Amazon EC2, Amazon VPC, and Amazon S3 are completely under your control and require you to perform all of the necessary Security configuration and management tasks. For example, for EC2 instances, you re responsible for management of the guest OS (including updates and Security patches), any application ArchivedAmazon Web Services Amazon Web Services: Overview of Security Processes Page 3 software or utilities you install on the instances, and the configuration of the AWS provided firewall (called a Security group) on each instance.
