AWS Redshift clusters configuration in a VPC for better cloud security

-

Security of data stored in cloud is a parameter that one should address on a priority basis. That said, VPCs helps in securing your data stored in AWS Redshift clusters ensures smooth and uninterrupted functioning.

AWS Redshift clusters should be associated with an AWS VPC

AWS VPC (Virtual Private Cloud) is a service that allows users to launch their resources in a logically isolated section of cloud. Users can provision their AWS Redshift clusters with a VPC which ensures security to your data as well as other resources on AWS.

It is recommended for users to create and manage their Redshift clusters in AWS EC2 VPC instead of AWS EC2 classic. AWS EC2 VPC is the updated technology which provides many advantages to the users such as better access control, better networking infrastructure, and access to the latest node types for better throughput, performance, etc.

Centilytics provides a dedicated insight that specifies whether your AWS Redshift clusters are associated with an AWS VPC or not.

Insight descriptions:

There can be 2 possible scenarios:

Severity Description
OK This indication will be displayed when your corresponding AWS Redshift cluster is associated with an AWS EC2 VPC
Warning This indication will be displayed when your corresponding AWS Redshift cluster is not associated with an AWS EC2 VPC

 

Descriptions of further columns are as follows:

  1. Account Id: This column Shows the respective account ID of the user’s account. AWS Redshift 3
  2. Account Name: This column shows the corresponding account name to the user’s account.AWS Redshift 7
  3. Region: This column shows the region in which the corresponding Redshift cluster exists.AWS Redshift 9
  4. Identifier: This column shows the name of the corresponding Redshift cluster.AWS Redshift 5
  5. Check VPC: This column shows the name of the VPC associated with your Redshift cluster.AWS Redshift 1

Filters applicable:

Filter Name Description
Account Id Applying the account Id filter will display data for the selected account Id.
Region Applying the region filter will display data according to the selected region.
Severity Applying severity filter will display data according to the selected severity type i.e. selecting critical will display all resources with critical severity. Same will be the case for warning and ok severity types
Resource Tags Applying resource tags filter will display those resources which have been assigned the selected resource tag. For e.g., A user has tagged some public snapshots by a resource tag named environment. Then selecting an environment from the resource tags filter will display all those resources tagged by the tag name environment.
Resource Tags Value Applying resource tags value filter will display data which will have the selected resource tag value. For e.g. – Let’s say a user has tagged some resource by a tag named environment and has a value say production (environment: production). Hence, the user can view data of all the resources which have “environment:production” tag assigned. The user can use the tag value filter only when a tag name has been provided.
