For eg- If the user has tagged some resource by a tag named environment, then selecting an environment from the resource tags filter will display all the data accordingly.Īpplying resource tags value filter will display data which will have the selected resource tag value. Same will be the case for warning and ok severity typesĪpplying resource tags filter will display those resources which have been assigned the selected resource tag. selecting critical will display all resources with critical severity.

Otherwise false will be displayed.Īpplying the account Id filter will display data for the selected account Id.Īpplying region filter will display data according to the selected region.Īpplying severity filter will display data according to the selected severity type i.e. If the cluster is encrypted, then true will be displayed. Encryption Status: This column shows the encryption status of the corresponding cluster specifying whether the cluster is encrypted or not.Identifier: This column shows the name of the corresponding redshift cluster.Region: This column shows the region in which the corresponding redshift cluster exists.Account Name: This column shows the corresponding account name to the user’s account.Account Id: This column Shows the respective account ID of the user’s account.This indication will be displayed when the corresponding redshift cluster does not have encryption enabled on AWS.ĭescription of further columns are as follows: This indication will be displayed when the corresponding redshift cluster has encryption enabled in AWS. There can be 2 possible scenarios: Severity How does Centilytics come into play?Ĭentilytics lists down all existing clusters and their corresponding encryption status for the users to act against them.

This is where cluster encryption plays an important role in encrypting and securing users’ data. When data is received from an unknown source, then security becomes a major concern as the user would want that no harm is caused to its own data because of any third-party intrusion. The cluster key then encrypts the database key for redshift cluster. It is stored in the disk in a separate network from the redshift cluster and gets passed on to the cluster through a secure channel. The database key, which is a randomly generated key, encrypts data encryption key in the cluster. These keys are encrypted using the database key for the cluster. Each data block is assigned a randomly generated key. Data encryption keys encrypt data blocks present in the redshift cluster. Redshift uses a four-tier, key-based architecture for data which consists of data encryption keys, a database key, a cluster key, and a master key. Also, any previously existing snapshots of that clusters get encrypted. When a cluster is modified to enable encryption, AWS automatically migrates the data present in the cluster to a new encrypted cluster. To encrypt redshift clusters, users can use either an AWS-managed key or a customer-managed key (CMK). AWS provides redshift cluster encryption through KMS (Key Management Service). Users can also modify an existing unencrypted cluster in AWS. Users can enable encryption when a new cluster is launched. Having explained, what is AWS Redshift & Redshift Cluster in my previous blog, let us now understand why its encryption is important. Why AWS Redshift cluster encryption is important for cloud security?

Redshift is the data warehouse and analytical service provided by AWS and it is essential to make sure that your redshift cluster is safe from any kind of potential, malicious security threat. Organizations want their cloud infrastructure to be completely secure so that they can focus on their business without getting worried about the safety of their deployed resources and workload. Cloud security is a vital aspect of cloud computing.
