Security FeaturesDell 7130cdn Professional Color PrinterSystem Administrator Guide39Before using HTTPS, you must set up a certificate and select when to use SSL to encrypt data.You can set the printer to use SSL either to secure Web pages that use passwords or to secureall Web pages.See also:Certificates on page 39Managing Certificates on page 42Configuring SSL on page 43CertificatesA certificate is an electronic message containing information about the printer and a digitalsignature.Before configuring passwords, set up a certificate and then configure SSL to encrypt data,including passwords, for maximum security. You can set up a self-signed certificate or downloada root-signed certificate, depending on your requirements.Device CertificatesA device certificate is stored in the printer and is used to validate the identity of the printer toclients and network servers and to allow encrypted communication. If you do not install a devicecertificate signed by a Certificate Authority (CA), a default self-signed device certificate isautomatically established on the printer when it is needed. A CA signed device certificate isneeded to log into the network when using 802.1X EAP authentication with TLS.Self-Signed CertificatesSetting up a self-signed certificate is a quick and easy way to establish a certificate on the printer.The printer automatically generates a default self-signed certificate when the printer is turned onfor the first time. To modify the certificate so it is specific to your printer, use the EWS to enterinformation about the location of the printer.While self-signed certificates are safe for most applications and allow data encryption, they do notensure valid authentication. Self-signed certificates are not necessarily secure because thecertificate owner is only confirming his own identify instead of verification by a trusted third party.Although self-signed certificates encrypt the data that is exchanged, they do not prevent man-in-the-middle attacks.If you want to use HTTPS, each printer must have a unique certificate that is accepted by eachbrowser used to access the printer. This allows the printer Web server to use HTTPS and encryptdata between the Web browser and the printer. In addition, because each printer’s certificate isunique, you must load a different certificate into the browser for each printer the browser willaccess.
