Resource summary

Question Answer
100-continue A method that enables a client to see if a server can accept a request before actually sending it. For large PUT requests, this method can save both time and bandwidth charges.
AAD additional authenticated data Information that is checked for integrity but not encrypted, such as headers or other contextual metadata
access control list (ACL) A document that defines who can access a particular bucket or object. Each bucket and object in Amazon S3 has an ACL. The document defines what each type of user can do, such as write and read permissions.
access identifiers credentials: Also called access credentials or security credentials. In authentication and authorization, a system uses credentials to identify who is making a call and whether to allow the requested access. In AWS, these credentials are typically the access key ID and the secret access key.
access key The combination of an access key ID (like AKIAIOSFODNN7EXAMPLE) and a secret access key (like wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY). You use access keys to sign API requests that you make to AWS.
access key ID A unique identifier that's associated with a secret access key; the access key ID and secret access key are used together to sign programmatic AWS requests cryptographically.
access key rotation A method to increase security by changing the AWS access key ID. This method enables you to retire an old key at your discretion.
access policy language A language for writing documents (that is, policies) that specify who can access a particular AWS resource and under what conditions.
account A formal relationship with AWS that is associated with (1) the owner email address and password, (2) the control of resources created under its umbrella, and (3) payment for the AWS activity related to those resources. The AWS account has permission to do anything and everything with all the AWS account resources. This is in contrast to a user, which is an entity contained within the account.
account activity A web page showing your month-to-date AWS usage and costs. The account activity page is located at
action An API function. Also called operation or call. The activity the principal has permission to perform. The action is B in the statement "A has permission to do B to C where D applies." For example, Jane sends a request to Amazon SQS with Action=ReceiveMessage. Amazon CloudWatch: The response initiated by the change in an alarm's state: for example, from OK to ALARM. The state change may be triggered by a metric reaching the alarm threshold, or by a SetAlarmState request. Each alarm can have one or more actions assigned to each state. Actions are performed once each time the alarm changes to a state that has an action assigned, such as an Amazon Simple Notification Service notification, an Auto Scaling policy execution or an Amazon EC2 instance stop/terminate action.
active trusted signers A list showing each of the trusted signers you've specified and the IDs of the corresponding active key pairs that Amazon CloudFront is aware of. To be able to create working signed URLs, a trusted signer must appear in this list with at least one key pair ID.
additional authenticated data Information that is checked for integrity but not encrypted, such as headers or other contextual metadata.
administrative suspension Auto Scaling might suspend processes for Auto Scaling group that repeatedly fail to launch instances. Auto Scaling groups that most commonly experience administrative suspension have zero running instances, have been trying to launch instances for more than 24 hours, and have not succeeded in that time.
alarm An item that watches a single metric over a specified time period, and triggers an Amazon SNS topic or an Auto Scaling policy if the value of the metric crosses a threshold value over a predetermined number of time periods.
allow One of two possible outcomes (the other is deny) when an IAM access policy is evaluated. When a user makes a request to AWS, AWS evaluates the request based on all permissions that apply to the user and then returns either allow or deny.
