CAUTION: Losing passwords can block access to an MFP. Be careful to record them in a safe place. Here is a list of the passwords you should configure: • Web Jetadmin password (required during installation of Web Jetadmin) • SNMPv3 credentials • EWS Password Use good practices for setting and updating passwords (some of the password settings have limitations on what and how many characters may be used): • Use alpha and numeric characters whenever possible. • For numeric only passwords use passwords with at least nine digits. • Use a different password for each password setting. Many of the latest password cracking tools can follow patterns to make guessing easier. • Avoid using a pattern for passwords. • Change the passwords often. • Use the maximum number of possible characters. Many of the password settings will accept as few as one character, but one character is easy to guess. Current data shows that nine characters or more are extremely difficult or almost impossible to guess using the latest password cracking tools. • Use complicated passwords. Use a variety of character types. Some of the passwords allow only numeric digits, but others can accept 96 or more different characters (upper case, lower case, numeric, special characters, and punctuation marks). • Use meaningless random passwords. Passwords that are real words or phrases are easier to guess. The latest password cracking tools follow dictionaries to narrow down the possibilities. • Record the passwords in a safe but hidden place. The passwords are designed to restrict access to management options on the MFPs. Losing a password can eliminate your access to settings. Getting Started This section provides instructions for configuring HP printers for best-practice security. All of these settings pertain to HP Web Jetadmin version 10.4 or later. Note: If you are setting this checklist for a group of several printers at once, Web Jetadmin will display all supported settings for all the MFPs it is managing, even though some of the MFPs may not support all of these settings. Each MFP ignores settings that do not apply to it and continues without issues. For instance, color settings are ignored for a non-color MFP. For the same reason, some of the settings may not appear in HP Web 10
