Data access in AWS involves controlling who can access your resources and how they access them. AWS offers several services and features designed specifically to control access to resources in a granular, robust, and straightforward manner.
AWS Identity and Access Management (IAM) is a significant service provided by AWS for controlling access. IAM allows you to manage access to AWS services and resources securely. With IAM, you can create and manage AWS users and groups and use permissions to allow and deny their access to AWS resources.
Here is an example of how you can create an IAM policy that allows full access to the Amazon DynamoDB service:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": "dynamodb:*",
"Resource": "*"
}
]
}
Another essential service is Amazon S3 that helps in managing access control using S3 buckets policy, access control lists, and IAM policies.
II. AWS Data Governance
Data governance in AWS refers to the overall management of data availability, usability, integrity, and security in an AWS environment. AWS provides a suite of tools which supports data governance, including AWS Config, AWS CloudTrail, AWS IAM, and AWS Macie, among others.
- AWS Config: This provides a detailed view of the resources associated with your AWS account, including how they are configured, how they are related to one another, and how the configurations and their relationships have changed over time.
- AWS CloudTrail: This service enables governance, compliance, operational auditing, and risk auditing of your AWS account. CloudTrail provides event history of your AWS account activity, including actions taken through the AWS Management Console.
- AWS IAM: It plays an essential role in data governance by providing user, role, policy and permission management.
- AWS Macie: This uses machine learning to recognize sensitive data such as personally identifiable information (PII) and provides you with dashboards and alerts that help you with the governance of your data.
AWS data governance not only ensures data quality and accessibility but also supports compliance with regulations like the General Data Protection Regulation (GDPR).
III. Balancing Data Access and Governance
Striking a balance between data access and governance in AWS is a critical task. You would need to ensure that while your data is easily accessible to authorised users and systems, it must also be protected and governed suitably. It is not just about granting and controlling access but also monitoring data usage, managing data throughout its lifecycle, and ensuring full compliance with all the necessary regulations.
In conclusion, data access and governance in AWS play a crucial role in the AWS Certified Solutions Architect – Associate (SAA-C03) exam. Understanding how different AWS services can be leveraged to control data access and ensure robust data governance is key to passing the exam and effectively administering AWS environments in the real world.
Practice Test
True or False: IAM roles can be used to delegate permissions to AWS services.
- True
- False
Answer: True
Explanation: IAM roles are a secure way to grant permissions to entities that you trust. These could be AWS services like EC2, or user applications.
In AWS, which of the following can be used to restrict access to data stored in S3?
- A) IAM Policy
- B) S3 Bucket Policy
- C) Access Control List (ACL)
- D) Service Control Policy
Answer: A) IAM Policy, B) S3 Bucket Policy and C) Access Control List (ACL)
Explanation: All three options can be used to restrict access to data in S IAM Policy is used to manage permissions and specify what actions are allowed or denied. S3 Bucket Policy is applied directly to an S3 bucket to control access while ACLs provide an additional layer of control over buckets and objects.
True or False: CloudTrail logs can be used for governance, compliance, operational auditing, and risk auditing of your AWS account.
- True
- False
Answer: True
Explanation: CloudTrail captures detailed event history of your AWS account activity, including actions taken through the AWS Management Console, AWS SDKs, command-line tools, and other AWS services. This can be used for governance, compliance, and auditing purposes.
In AWS, which service helps you to manage secrets?
- A) AWS Secrets Manager
- B) AWS Key Management Service
- C) AWS Cryptographic services
- D) AWS CloudHSM
Answer: A) AWS Secrets Manager
Explanation: AWS Secrets Manager helps you protect access to your IT resources. This service enables you to easily rotate, manage, and retrieve database credentials, API keys, and other secrets throughout their lifecycle.
Which AWS service helps you to classify, secure, and monitor sensitive data?
- A) Macie
- B) Athena
- C) Glue
- D) Shield
Answer: A) Macie
Explanation: AWS Macie is a fully managed data privacy and security service that uses machine learning and pattern matching to discover and protect your sensitive data in AWS.
True or False: You need to encrypt data at rest in AWS directly through the Amazon S3 console.
- True
- False
Answer: False
Explanation: While you can enable encryption on S3 directly, AWS also provides SDKs and APIs for common programming languages so you can manage encryption programmatically.
Multiple Select: Which of the following are recommended for data governance in AWS?
- A) Implement Access Controls
- B) Audit actions
- C) Encrypt sensitive data
- D) Share AWS account credentials with all team members
Answer: A) Implement Access Controls, B) Audit actions and C) Encrypt sensitive data
Explanation: In data governance, it’s essential to control who has access to data, monitor actions on data, and encrypt sensitive data. Sharing AWS account credentials with all team members is not recommended.
Which AWS service is used to enforce compliance controls across your AWS accounts?
- A) CloudWatch
- B) Config
- C) Shield
- D) CloudTrail
Answer: B) Config
Explanation: AWS Config continuously monitors and records your AWS resource configurations and allows you to automate the evaluation of recorded configurations against desired configurations.
True or False: AWS recommends that you root your AWS account regularly.
- True
- False
Answer: False
Explanation: AWS recommends using IAM users for everyday interaction with AWS, instead of the root account. The root account should be used sparingly and protected with strong security measures.
