What are the two ways to control access to the S3 buckets?

Restrict access to your S3 buckets or objects by doing the following:

• Writing IAM) user policies that specify the users that can access specific buckets and objects.
• Writing bucket policies that define access to specific buckets and objects.

What is fine-grained access control?

Fine-grained access control is a method of controlling who can access certain data. Most often used in cloud computing where large numbers of data sources are stored together, fine-grained access control gives each item of data its own specified policy for access.

What is fine-grained access control in AWS?

The third and final security layer is fine-grained access control. After a resource-based access policy allows a request to reach a domain endpoint, fine-grained access control evaluates the user credentials and either authenticates the user or denies the request.

How can control access to the data stored in AWS S3?

VPC endpoints for Amazon S3 provide multiple ways to control access to your Amazon S3 data:

1. You can control the requests, users, or groups that are allowed through a specific VPC endpoint.
2. You can control which VPCs or VPC endpoints have access to your S3 buckets by using S3 bucket policies.

Which of the following strategies can be used to restrict access to data in S3?

Set an S3 Bucket policy. Enable IAM Identity Federation. Set an S3 ACL on the bucket or the object.

What is fine-grained and coarse grained access control?

The definitions start to hint at what the differences might be: fine-grained access control will work on smaller items whereas coarse-grained access control will work on larger items. Granularity can apply to the message being intercepted or the information being considered for access control.

What is fine-grained data?

Fine-grained parallelism means individual tasks are relatively small in terms of code size and execution time. The data is transferred among processors frequently in amounts of one or a few memory words. Coarse-grained is the opposite: data is communicated infrequently, after larger amounts of computation.

What is coarse grained access control?

coarse grained authorization. Granularity which literally means “level or scale of detail” and hence granularity in authorization means the level of details used to put on authorization rules for evaluating a decision to grant or deny the access.

What is the security module that is used to fine-grained control the access of data lake?

Setting up Lake Formation Amazon EMR integrates with Lake Formation and its security model to allow fine-grained access control on databases, tables, and columns defined in the Data Catalog for data stored in Amazon S3.

What are different types of access control in terms of S3?

There are two types of ACLs available when leveraging S3: Bucket and Object. Bucket ACLs allow you to control access at a bucket level, while Object ACLs allow you to control access at the object level.

What is access control List in AWS?

Amazon S3 access control lists (ACLs) enable you to manage access to buckets and objects. Each bucket and object has an ACL attached to it as a subresource. It defines which AWS accounts or groups are granted access and the type of access.

What is fine-grained access control and why do you need it?

You could use fine-grained access control to: Enable ad hoc production database access to a new set of business users or testers without fear of exposing private data. Rapidly correct critical security vulnerabilities while permanent solutions are developed at the database or application level.

What is an Amazon S3-based data lake?

The Amazon S3-based data lake solution uses Amazon S3 as its primary storage platform. Amazon S3 provides an optimal foundation for a data lake because of its virtually unlimited scalability. You can seamlessly and nondisruptively increase storage from gigabytes to petabytes of content, paying only for what you use.

What is Amazon S3 and why should you care?

With Amazon S3, you can cost-effectively store all data types in their native formats. You can then launch as many or as few virtual servers as you need using Amazon Elastic Compute Cloud (EC2), and you can use AWS analytics tools to process your data.
