The application must enforce password complexity by requiring that at least one special character be used.
Vulnerability discussion
Use of passwords for application authentication is intended only for limited situations and should not be used as a replacement for two-factor CAC-enabled authentication.Examples of situations where a user ID and password might be used include but are not limited to:- When the application user base does not have a CAC and is not a current DoD employee, member of the military, or a DoD contractor.- When an application user has been officially designated as a Temporary Exception User; one who is temporarily unable to present a CAC for some reason (lost, damaged, not yet issued, broken card reader) and to satisfy urgent organizational needs must be temporarily permitted to use user ID/password authentication until the problem with CAC use has been remedied.and- When the application is publicly available and or hosting publicly releasable data requiring some degree of need-to-know protection.Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks.Password complexity is one factor of several that determine how long it takes to crack a password. The more complex the password, the greater the number of possible combinations that need to be tested before the password is compromised.
Check content
Review the application documentation and interview the application administrator to identify if the application uses passwords for user authentication.
If the application does not use passwords, the requirement is not applicable.
Access the application management interface and create a test user account or logon to the system with a test account and access the functionality that provides password change capabilities.
When prompted to provide the password, attempt to create a password that does not have one special character.
If a password without at least one special character can be created, this is a finding.
Fix text
Configure the application to require at least one special character in the password.
Pro Tips
Lavender hyperlinks in small type off to the right (of CSS
class id, if you view the page source) point to
globally unique URIs for each document and item. Copy the
link location and paste anywhere you need to talk
unambiguously about these things.
You can obtain data about documents and items in other
formats. Simply provide an HTTP header Accept:
text/turtle or
Accept: application/rdf+xml.
