How to Use AWS S3 Inventory and Batch Operations for Better Protection?

Amazon Web Service is a comprehensive cloud platform, offering 175 features services globally. AWS S3 is one of the tools that help you manage storage. Here we have discussed how to use AWS S3 inventory to secure data.

AWS S3 Inventory and Batch Operations

Understanding Amazon S3 Inventory

The S3 is an essential element in cloud security AWS. The S3 inventory provides Apache Parquet, Apache-optimized row columnar, and comma-separated-values output files to list your object. It also lists corresponding metadata daily for an S3 bucket. You can use it for auditing and reporting on the replication and encryption status of your business objects.

How to Set Up an AWS S3 Inventory?

The bucket that lists the objects is called the source object. The bucket, which stores inventory lists, is called the destination bucket. To set up an S3 inventory for secured success, you need to do the following:

Add a Bucket Policy for Destination Bucket

You need to create a bucket policy on the destination bucket. It will grant permission to AWS S3 to write objects to the object in the defined location.

Encrypt the Inventory List With SSE-KMS

You can use the AWS console to encrypt the inventory list file. You need to manage the critical policy to grant Amazon S3 permission to encrypt the inventory file.

Understanding S3 Batch Operations in AWS

S3 batch operations allow the user to perform large-scale operations on Amazon s3 objects. The S3 batch operations can be used for the following purposes:

  • Copy objects
  • Set object tags or control lists
  • Initiate object restores from Amazon glacier
  • Invoke an AWS Lambda function to perform custom actions

Following the best security practices is the key to better protection on the cloud security AWS.

AWS S3 Preventative Best Practices

Following these best security practices can help prevent security incidents:

  • You need to ensure the AWS S3 buckets use correct policies and are not publicly accessible. Account admins can use Amazon S3 block access to set up centralized controls and block public access. This will ensure the buckets will not have access to unlimited Amazon S3 resources, regardless of the created resources.
  • Identify S3 policies that allow wildcard identities, such as principal, which means anyone and a wildcard action “*,” allowing users to perform any action.
  • Note down AWS S3 bucket lists that provide read, write, and full-access rights to everyone or any AWS authenticated user.
  • Use the ListBuckets API to scan all your Amazon S3 buckets. You can then use API requests like GetBucketPolicy, GetBucketWebsite, and GetBucketAc1 to determine whether the bucket has compliant controls and permissions.

AWS S3 Monitoring and Auditing Best Practices

The S3 auditing and monitoring best practices allow you to find potential weaknesses and incidents. Identification of IT assets is a crucial aspect of security and governance. Having clear visibility of all AWS S3 resources will help assess security posture and take remedial action to overcome weaknesses. Here are some best practices you can follow:

Implement Monitoring

AWS provides several tools and services to monitor Amazon S3 components. For example, you can monitor CloudWatch metrics for GetRequests, 4xxErrors, PutRequests, and DeleteRequest

Enable Server Access Logging

Server access logs provide complete details of requests made to the bucket. These access logs can help access audits and security. You can also implement ongoing detective controls using the AWS Config managed rule.

Use CloudTrail

AWS CloudTrail provides a record of action taken by a role, a user, or AWS service. The information can be used to determine who made the request when it was made, the IP address used for the request, and additional details.

The Amazon S3 allows object storage through a web interface. The information given in the post gives you important information about the working and setup of S3 and the best security practices to follow for optimal security of your data on the AWS platform.
