Security Features Basic Concepts This section includes: • Admin and Key User Accounts • HTTP, HTTPS, and SSL/TLS • Certificates • ColorTrack Lists Admin and Key User Accounts Admin and Key User accounts in the EWS enable you to limit access to specific printer functions by specifying passwords for user classes. The EWS requires a name and password before access to the controlled printer functions is allowed. The user classes are: • Administrator: The person with the ultimate management responsibility and authority for controlling some or all of the printer functions. • Key User: A person who has some administrative responsibilities and who manages some or all of the printer functions. • Any User: Includes the majority of people who will be sending print jobs to the printer. Once the passwords are set, select the printer functions from the Feature Authorization list that each user class has the right to access. The three categories of printer functions are: • Administrative • Web Server Printing • Printer Neighborhood See also: Configuring Administrator and Key User Settings on page 44 HTTP, HTTPS, and SSL/TLS HTTP (Hyper Text Transfer Protocol) is used to communicate across the Internet between the printer Web server and the Web browser (clients). Because the data is transmitted in plain text and passwords are only slightly encrypted, it is not secure; the data can be read or intercepted by other people. HTTPS (Secure Hyper Text Transfer Protocol) is a secure version of HTTP. HTTPS provides authentication and encrypted communication to preserve the confidentiality of your data. Instead of using plain text, HTTPS uses either the SSL (Secure Socket Layer) protocol or the TLS (Transport Layer Security) protocol to encrypt data, thus ensuring reasonable protection from eavesdroppers and man-in-the-middle attacks. 38 Dell 7130cdn Professional Color Printer System Administrator Guide
