Logging and auditing
Unlike the identity services that merited their own chapters, or even the services we looked at earlier within this chapter, AWS CloudTrail and Amazon CloudWatch may not seem worth much of a mention. However, logging and auditing are essential components of non-repudiation. Non-repudiation is when we have assurances that something, such as an action, signature, or event, cannot be denied by a person. IAM ties the event, action, account, and others to the individual, and auditing and logging help prove that the event occurred.
We will quickly look at the two services AWS provides for audit and logging. The first is AWS CloudTrail, which captures the events that occur within an AWS account. The second is Amazon CloudWatch, which is a monitoring and logging service that can be used with AWS services and resources.
