Password strength in Cloud Platform

Cloud Platform enforces a security policy for passwords used to access the Cloud Platform user interface. This security policy determines how strong (resistant to guessing) user’s passwords must be.

The password strength policy applies only to the Cloud Platform user interface, and doesn’t apply to your Drupal websites.

Note

For password security policies in Site Factory, see Minimum password strength.

Password requirements on Cloud Platform

Cloud Platform applies several rules to test a password’s strength, based on the entropy (randomness) of the sequences in the password. All passwords used for accessing the Cloud Platform user interface must meet the following criteria:

  • Is at least 12 characters in length
  • Has at least one capital letter
  • Has at least one lower case letter
  • Has at least one special character
  • Doesn’t reuse any of the user’s previous 24 passwords

Testing password security when changing passwords

As you type a new password, the Acquia password policy system tests and reports the password’s strength. If you try to create a password that doesn’t meet Acquia’s password strength requirements, Cloud Platform will display an error message describing why the password strength is insufficient, such as the following message:

The following issues were detected with your password:
* Passwords must be at least 12 characters in length.
* Passwords must contain at least 1 capital letter.
* Passwords must contain at least 1 number.
* Passwords must contain at least 1 special character.

Protecting against brute-force attacks

The Cloud Platform user interface protects you from brute-force attacks by the following policies limiting the total number of sign-in attempts:

  • After three failed sign-in attempts during a 30 minute timeframe from a single user and IP address, Cloud Platform blocks the user name (email) and IP address combination from signing in for one hour.
  • After 50 failed sign-in attempts in an hour from a single IP address, Cloud Platform blocks the IP address from signing in for one hour.
