Managing the security audit log • To view or save a text file of the current syslog, click Export Log. • To delete the current syslog, click Delete Log. Updating firmware Devices inspect all downloaded firmware packages for a number of required attributes before adopting and executing the packages. The firmware must be packaged in a proprietary format and encrypted with a symmetric encryption algorithm through an embedded key that is known only to Lexmark. However, the strongest security measure comes from requiring all firmware packages to include multiple digital 2048-bit RSA signatures from Lexmark. If these signatures are not valid, or if the message logs indicate a change in firmware after the signatures were applied, then the firmware is discarded. 1 From the Embedded Web Server, click Settings > Update Firmware. 2 Browse to the flash file. 3 Click Submit.
