AWS Key Management Service (KMS) Monitoring Integration

AWS Key Management Service (KMS) is managed service that enables you to create and manage the encryption keys used to encrypt data. With Site24x7's integration you can track and alert on key material expiration for CMKs whose origin is external.

Setup and configuration

  • If you haven't done it already enable programmatic access to your AWS resources either by creating IAM user for Site24x7 or create a cross-account IAM Role between your AWS account and Site24x7's AWS account. Learn more.
  • In the integrate AWS Account page, make sure you select the check box next to the KMS service. Learn more.

Policy and Permission

Site24x7 uses various KMS service APIs to collect information about the customer master keys. Assign the AWS Managed policy ReadOnlyAccess to the Site24x7 entity (IAM user or IAM Role) to help Site24x7 collect metrics and metadata. If you want to assign a custom policy, please make sure the following read-level actions are present in the policy JSON. Learn more.

  • kms:Describe*
  • kms:Get*
  • kms:List*

Polling frequency

Site24x7 collects metric data for your customer managed CMKs as per the poll frequency set (1 minute to a day). Learn more.

Licensing

Each customer managed CMK is considered a basic monitor. Learn more.

Supported metrics

The following metrics are collected:

AttributeDescription
Minutes until key material expiration Measures the number of minutes remaining until imported key material expires (applicable for CMKs whose origin is external).
Hours remaining until key material expiration Measures the number of hours remaining until imported key material expires (applicable for CMKs whose origin is external)
Days remaining until key material expiration Measures the number of days remaining until imported key material expires (applicable for CMKs whose origin is external).
Minutes until Customer Master Key (CMK) deletion. Measures the number of minutes remaining until a CMK is deleted (applicable for CMKs scheduled for deletion).
Hours until Customer Master Key (CMK) deletion. Measures the number of hours remaining until a CMK is deleted (applicable for CMKs scheduled for deletion).
Days until Customer Master Key (CMK) deletion. Measures the number of hours remaining until a CMK is deleted. (applicable for CMKs scheduled for deletion)
Key age Measures the number of days since the customer managed CMK was created (The value is calculated using the creation date metadata).

AWS KMS Monitoring UI pages

Summary

The Summary tab displays time series charts for KMS metrics and other metadata like key age.

Key Policy

Key policies determines who can use and manage that CMK. The key policy JSON attached to the specified customer master key (CMK) is displayed in the tab.

Grants
