Authentication, Authorization & Accounting
Cloud Security is a huge topic, mainly because it has so many different areas of focus. This course focuses on three areas that are fundamental, AWS Authentication, Authorisation and Accounting.
These three topics can all be linked together and 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. Once an identity has been authenticated and is authorised to perform specific functions it's then important that this access can be tracked with regards to usage and resource consumption so that it can be audited, accounted and billed for.
The course will define and discuss each area, and iron out any confusions of meaning between various security terms. Some people are unaware of the differences between authentication, authorization and access control, this course will clearly explain the differences here allowing you to use the correct terms to describe your security solutions.
From an AWS authentication perspective, a number of different mechanisms are explained, such as Multi-Factor AWS Authentication (MFA), Federated Identity, Access Keys and Key Pairs. With the help of demonstrations, you can learn how to apply access keys to your AWS CLI for programmatic access and understand the differences between Linux and Windows authentication methods using AWS Key Pairs.
When we dive into understanding authorization we cover IAM Users, Groups, Roles and Policies, providing examples and demonstrations. Within this section, S3 authorization is also discussed, looking at access control lists (ACLs) and Bucket Policies. Moving on from S3, we look at network and instance level authorization with the help of Network Access Control Lists (NACLs) and Security Groups.
Finally, the Accounting section will guide you through the areas of Billing & Cost Management that you can use to help identify potential security threats. In addition to this, we explain how AWS CloudTrail can be used to track API calls to analyse what users are doing and when. This makes CloudTrail a strong tool in tracking, identifying and monitoring a user's actions within your AWS environment.
