Vulnerability discussion

Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. The shorter the password, the lower the number of possible combinations that need to be tested before the password is compromised. Use of more characters in a password helps to exponentially increase the time and/or resources required to compromise the password.Compliance with this requirement also prevents the system from being configured with default or no passwords.

Check content

Verify the SRX password enforces this complexity requirement. In configuration mode, enter the following command. [edit] show system login password If the minimum password length for local accounts is not set to at least a 15-character length, this is a finding.

Fix text

Set the global password option for all accounts created on the Juniper SRX. [edit] set system login password minimum-length 15 Note: This setting only enforces the minimum character password length for newly created passwords. The password of the existing account must be changed if it is not already complaint. To set or change the root user password, in configuration mode enter the following command. [edit] set system root-authentication plain-text-password When prompted, enter the password for the root user. Retype new password to confirm To set or change the account of last resort, in configuration mode enter the following command. [edit] set system login user plain-text-password When prompted, enter the password for the root user. Retype new password to confirm

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.
