Introduction to AWS Security AWS WhitepaperAbstractIntroduction to AWS SecurityPublication date: January 22, 2020 (Document Revisions (p. 9))AbstractAmazon Web Services (AWS) delivers a scalable cloud computing platform designed for high availabilityand dependability, providing the tools that enable you to run a wide range of applications. Helpingto protect the confidentiality, integrity, and availability of your systems and data is of the utmostimportance to AWS, as is maintaining your trust and confidence. This document is intended to provide anintroduction to AWS’s approach to security, including the controls in the AWS environment and some ofthe products and features that AWS makes available to customers to meet your security objectives.1

Introduction to AWS Security AWS WhitepaperSecurity of the AWS InfrastructureThe AWS infrastructure has been architected to be one of the most flexible and secure cloud computingenvironments available today. It is designed to provide an extremely scalable, highly reliable platformthat enables customers to deploy applications and data quickly and securely.This infrastructure is built and managed not only according to security best practices and standards,but also with the unique needs of the cloud in mind. AWS uses redundant and layered controls,continuous validation and testing, and a substantial amount of automation to ensure that the underlyinginfrastructure is monitored and protected 24x7. AWS ensures that these controls are replicated in everynew data center or service.All AWS customers benefit from a data center and network architecture built to satisfy the requirementsof our most security-sensitive customers. This means that you get a resilient infrastructure, designed forhigh security, without the capital outlay and operational overhead of a traditional data center.AWS operates under a shared security responsibility model, where AWS is responsible for the securityof the underlying cloud infrastructure and you are responsible for securing workloads you deploy inAWS (Figure 1). This gives you the flexibility and agility you need to implement the most applicablesecurity controls for your business functions in the AWS environment. You can tightly restrict access toenvironments that process sensitive data, or deploy less stringent controls for information you want tomake public.Figure 1: AWS Shared Security Responsibility Model2

Introduction to AWS Security AWS WhitepaperInfrastructure SecuritySecurity Products and FeaturesAWS and its partners offer a wide range of tools and features to help you to meet your securityobjectives. These tools mirror the familiar controls you deploy within your on-premises environments.AWS provides security-specific tools and features across network security, configuration management,access control and data security. In addition, AWS provides monitoring and logging tools to can providefull visibility into what is happening in your environment.Topics Infrastructure Security (p. 3) Inventory and Configuration Management (p. 3) Data Encryption (p. 3) Identity and Access Control (p. 4) Monitoring and Logging (p. 4) Security Products in AWS Marketplace (p. 5)Infrastructure SecurityAWS provides several security capabilities and services to increase privacy and control network access.These include: Network firewalls built into Amazon VPC let you create private networks and control access to yourinstances or applications. Customers can control encryption in transit with TLS across AWS services. Connectivity options that enable private, or dedicated, connections from your office or on-premisesenvironment. DDoS mitigation technologies that apply at layer 3 or 4 as well as layer 7. These can be applied as partof application and content delivery strategies. Automatic encryption of all traffic on the AWS global and regional networks between AWS securedfacilities.Inventory and Configuration ManagementAWS offers a range of tools to allow you to move fast, while still enabling you to ensure that your cloudresources comply with organizational standards and best practices. These include: Deployment tools to manage the creation and decommissioning of AWS resources according toorganization standards. Inventory and configuration management tools to identify AWS resources and then track and managechanges to those resources over time. Template definition and management tools to create standard, preconfigured, hardened virtualmachines for EC2 instances.Data EncryptionAWS offers you the ability to add a layer of security to your data at rest in the cloud, providing scalableand efficient encryption features. These include:3

Introduction to AWS Security AWS WhitepaperIdentity and Access Control Data at rest encryption capabilities available in most AWS services, such as Amazon EBS, Amazon S3,Amazon RDS, Amazon Redshift, Amazon ElastiCache, AWS Lambda, and Amazon SageMaker Flexible key management options, including AWS Key Management Service, that allow you to choosewhether to have AWS manage the encryption keys or enable you to keep complete control over yourown keys Dedicated, hardware-based cryptographic key storage using AWS CloudHSM, allowing you to helpsatisfy your compliance requirements Encrypted message queues for the transmission of sensitive data using server-side encryption (SSE) forAmazon SQSIn addition, AWS provides APIs for you to integrate encryption and data protection with any of theservices you develop or deploy in an AWS environment.Identity and Access ControlAWS offers you capabilities to define, enforce, and manage user access policies across AWS services.These include: AWS Identity and Access Management (IAM) lets you define individual user accounts with permissionsacross AWS resources AWS Multi-Factor Authentication for privileged accounts, including optionsfor software- and hardware-based authenticators. IAM can be used to grant your employees andapplications federated access to the AWS Management Console and AWS service APIs, using yourexisting identity systems, such as Microsoft Active Directory or other partner offering. AWS Directory Service allows you to integrate and federate with corporate directories to reduceadministrative overhead and improve end-user experience. AWS Single Sign-On (AWS SSO) allows you to manage SSO access and user permissions to all of youraccounts in AWS Organizations, centrally.AWS provides native identity and access management integration across many of its services, plus APIintegration with any of your own applications or services.Monitoring and LoggingAWS provides tools and features that enable you to see what’s happening in your AWS environment.These include: With AWS CloudTrail, you can monitor your AWS deployments in the cloud by getting a history of AWSAPI calls for your account, including API calls made via the AWS Management Console, the AWS SDKs,the command line tools, and higher-level AWS services. You can also identify which users and accountscalled AWS APIs for services that support CloudTrail, the source IP address the calls were made from,and when the calls occurred. Amazon CloudWatch provides a reliable, scalable, and flexible monitoring solution that you can startusing within minutes. You no longer need to set up, manage, and scale your own monitoring systemsand infrastructure. Amazon GuardDuty is a threat detection service that continuously monitors for malicious activity andunauthorized behavior to protect your AWS accounts and workloads. Amazon GuardDuty exposesnotifications via Amazon CloudWatch so you can trigger an automated response or notify a human.These tools and features give you the visibility you need to spot issues before they impact the businessand allow you to improve security posture, and reduce the risk profile, of your environment.4

Introduction to AWS Security AWS WhitepaperComplianceAWS Compliance empowers customers to understand the robust controls in place at AWS to maintainsecurity and data protection in the AWS Cloud. When systems are built in the AWS Cloud, AWS andcustomers share compliance responsibilities. AWS computing environments are continuously audited,with certifications from accreditation bodies across geographies and verticals, including SOC 1/SSAE 16/ISAE 3402 (formerly SAS 70), SOC 2, SOC 3, ISO 9001 / ISO 27001, FedRAMP, DoD SRG, and PCI DSSLevel 1.i. Additionally, AWS also has assurance programs that provide templates and control mappingsto help customers establish the compliance of their environments running on AWS, for a full list ofprograms, see AWS Compliance Programs.We can confirm that all AWS services can be used in compliance with the GDPR. This means that, inaddition to benefiting from all of the measures that AWS already takes to maintain services security,customers can deploy AWS services as a part of their GDPR compliance plans. AWS offers a GDPRcompliant Data Processing Addendum (GDPR DPA), enabling you to comply with GDPR contractualobligations. The AWS GDPR DPA is incorporated into the AWS Service Terms and applies automaticallyto all customers globally who require it to comply with the GDPR. Amazon.com, Inc. is certified underthe EU-US Privacy Shield and AWS is covered under this certification. This helps customers who chooseto transfer personal data to the US to meet their data protection obligations. Amazon.com Inc.’scertification can be found on the EU-US Privacy Shield website: https://www.privacyshield.gov/listBy operating in an accredited environment, customers reduce the scope and cost of audits they needto perform. AWS continuously undergoes assessments of its underlying infrastructure—including thephysical and environmental security of its hardware and data centers—so customers can take advantageof those certifications and simply inherent those controls.In a traditional data center, common compliance activities are often manual, periodic activities. Theseactivities include verifying asset configurations and reporting on administrative activities. Moreover,the resulting reports are out of date before they are even published. Operating in an AWS environmentallows customers to take advantage of embedded, automated tools like AWS Security Hub, AWS Configand AWS CloudTrail for validating compliance. These tools reduce the effort needed to perform audits,since these tasks become routine, ongoing, and automated. By spending less time on manual activities,you can help evolve the role of compliance in your company from one of a necessary administrativeburden, to one that manages your risk and improves your security posture.7
