Description:

This policy ensures that Amazon Elasticsearch Service (ES) domains have the latest security updates and bug fixes. This is important to do because security vulnerabilities can be exploited by attackers to gain access to your data or disrupt your services.

Rationale:

Keeping your ES domains up to date with the latest security updates is important for the following reasons:

  • It helps to protect your data from being compromised.
  • It helps to prevent attackers from disrupting your services.
  • It helps to improve the performance and reliability of your ES domains.

Impact:

If you do not keep your ES domains up to date with the latest security updates, you could be at risk of the following:

  • Data breaches
  • Service disruptions
  • Performance degradation

Default Value:

AWS will recommend that you keep your ES domains up to date with the latest security updates.

Pre-Requisite:

  • You must have access to the AWS Management Console or the AWS CLI.
  • You must have the IAM permissions necessary to manage ES domains.

Remediation Steps:

To ensure that your ES domains have updates available, you can follow these steps:

  1. Check the status of your ES domains by using the AWS Management Console or the AWS CLI.
  2. If any of your domains are not up to date, you can start the upgrade process.
  3. Monitor the upgrade process to ensure that it completes successfully.

Test Plan:

To test whether your ES domains have updates available, you can follow these steps:

  1. Use the AWS Management Console or the AWS CLI to check the status of your ES domains.
  2. If any of your domains are not up to date, you can start the upgrade process.
  3. Once the upgrade process is complete, you can verify that your domains are up to date by checking the status again.

Implementation Plan:

To implement this policy, you can follow these steps:

  1. Create a policy that grants IAM users the permissions necessary to manage ES domains.
  2. Attach the policy to the IAM users who need to be able to manage ES domains.
  3. Use the AWS Management Console or the AWS CLI to check the status of your ES domains.
  4. If any of your domains are not up to date, you can start the upgrade process.
  5. Monitor the upgrade process to ensure that it completes successfully.

AWS CLI Process:

To use the AWS CLI to ensure that your ES domains have updates available, you can use the following command:

aws es describe-domains --domain-names my-domain-1,my-domain-2

This command will list the status of your ES domains. If any of your domains are not up to date, you can use the following command to start the upgrade process:

aws es upgrade-domain --domain-name my-domain-1

Using AWS GUI:

To use the AWS Management Console to ensure that your ES domains have updates available, you can follow these steps:

  1. Go to the AWS Management Console and sign in to your account.
  2. Click on the "Elasticsearch Service" service.
  3. Click on the "Domains" tab.
  4. Select the domains that you want to check for updates.
  5. Click on the "Upgrade" button.

Backout Plan:

To back out of this policy, you can follow these steps:

  1. Stop the upgrade process for any ES domains that are currently being upgraded.
  2. Delete the policy that grants IAM users the permissions necessary to manage ES domains.

Note:

  • This policy is only applicable to ES domains that are running Elasticsearch 5.x or above.
  • This policy does not apply to ES domains that are running in a VPC.
