Description

In this section of the AWS Certified: SAP on AWS Specialty learning path, we introduce you to the various Security services currently available in AWS that are relevant to the PAS-C01 exam.

Learning Objectives

  • Understand the purpose of AWS user and identity management
  • Identify resources and capabilities for AWS network security
  • Understand how to evaluate the security of an AWS environment
  • Describe AWS services used to create a comprehensive security solution for SAP deployments

Prerequisites

The AWS Certified: SAP on AWS Specialty certification has been designed for anyone who has experience managing and operating SAP workloads. Ideally you’ll also have some exposure to the design and implementation of SAP workloads on AWS, including migrating these workloads from on-premises environments. Many exam questions will require a solutions architect level of knowledge for many AWS services, including AWS Security services. All of the AWS Cloud concepts introduced in this course will be explained and reinforced from the ground up.

Transcript

Hello and welcome to this lecture where I shall provide an overview of what the Identity & Access Management service is, and what IAM actually means.

Firstly I want to define what is meant by Identity & Access Management and I shall break this down into two parts, starting with Identity Management. 

Identities, such as AWS usernames are required to authenticate you to your AWS account, and this authentication process is managed in 2 stages.

  1. The first part of this process is to define who you are, effectively presenting your identity, so for example your AWS username.  This identification is a unique value within IAM for your account, so this means IAM would prevent you from having 2 identical user accounts with the same name within the same AWS account.
  2. The second part of the authentication process is to verify that you are who you say you are. This is achieved by supplying additional data, and when using our AWS usernames we can verify this by supplying a password

Now, Access Management relates to authorization and access control.  Authorization determines what an identity can access within your AWS account once it’s been authenticated to it.  An example of this authorization would be the user’s list of permissions to access specific AWS resources, for example, they might have Full Access to EC2 or Read Only to RDS.

Access Control can be classed as the mechanism of accessing a secured resource.  For example, using the following:

  • Username and password (Authentication and Verification)
  • Multi-Factor Authentication (MFA, used as an additional verification step following a valid password)
  • Or Federated Access, which allows users external to AWS to access resources securely without having to supply AWS user credentials from a valid IAM user account.  Instead, these credentials are supplied from identity providers.  For more information on Identity Federation, please see our existing course here: https://cloudacademy.com/course/using-aws-identity-federation-simplify-access-scale-1549/

So essentially IAM can be defined by its ability to manage, control, and govern authentication, authorization, and access control mechanisms of identities to your resources within your AWS Account.

Having an understanding of the different security controls from an authentication and authorization perspective can help you design the correct level of security for your infrastructure.
