Cis Docker V170 7.6

CIS Docker Benchmark v1.7.0 - Control 7.6

Profile Applicability

• Level: 1
• Type: Manual
• Platform: Docker Swarm

Description

You should rotate the swarm manager auto-lock key periodically.

Rationale

The swarm manager auto-lock key is not automatically rotated. Good security practice is to rotate keys.

Impact

None

Audit Procedure

Currently, there is no mechanism to find out when the key was last rotated on a swarm manager node. You should check with the system administrator to see if there is a key rotation process, and how often the key is rotated.

Remediation

You should run the command below to rotate the keys.

docker swarm unlock-key --rotate

Additionally, to facilitate auditing of this recommendation, you should maintain key rotation records and ensure that you establish a pre-defined frequency for key rotation.

Default Value

By default, keys are not rotated automatically.

CIS Controls

v8:

• 5.2 Use Unique Passwords
  • Use unique passwords for all enterprise assets. Best practice implementation includes, at a minimum, an 8-character password for accounts using MFA and a 14-character password for accounts not using MFA.

v7:

• 4.4 Use Unique Passwords
  • Where multi-factor authentication is not supported (such as local administrator, root, or service accounts), accounts will use passwords that are unique to that system.
