2 Security Functions 2.2 - Secure LAN: Be sure to connect the machine to a local area network protected by firewall in order to prohibit access from external networks. - An administrator should designate the installation location to be available only for product users. - An administrator is required to be present at customer engineer (CE) works such as installation or maintenance. 2.2.3 Description of Enhanced Security Mode Security functions will be enhanced as follows. Protecting and deleting of remaining data after being used There are two types of Image data stored in memory or HDD: AHA compressed data and uncompressed data, which are TIFF format, PDF format, and PS data. The image area of memory or HDD with AHA compressed data will be released after clearing the used data. In normal mode, the data is not completely deleted, which may allow for unauthorized reading of the data. In Enhanced Security mode, the image area of memory or HDD is overwritten with data unrelated to the image before the area is released, irrespective of whether the stored image data is compressed. Enhanced passwords There are 5 different passwords provided for security functions. - CE password - Administrator password - User password - Account password - HDD lock password The CE authentication password, administrator password, and account password should be comprised of 8 alphanumeric characters and/or symbols (the alphabetic characters are case-sensitive). The user password is normally made from 1 to 64 alphanumeric characters (case-sensitive); however, the user password less than 8 characters will be unavailable in the Enhanced Security mode. The machine in the Enhanced Security mode also refuses any entry for 5 seconds, if a wrong password is entered for one of the 5 passwords mentioned above. Should you forget any security-related password, please take action as follows depending on the type of password. - For a user password or account password, please contact your administrator. - If you have forgotten the administrator password or HDD lock password, please contact your service representative. We recommend that each password should be changed on a regular basis in order to prevent illicit access or falsification of data. Data access Ensure that a user is required to enter an enhanced password which has been set by the administrator, in order to save data into the user box stored in HDD or output the stored data. When saving scanned data into a user box, you can improve security by setting an enhanced password. Only administrators can delete folders and user boxes in which scanned data resides. Once a user box attribute has been changed, user authentication with an enhanced password is required. User authentication is also required for using saved scanned data. Machine NIC settings While the Enhanced Security mode is activated, the machine NIC cannot be used. Blocking external accesses No access is allowed over telephone lines other than CS Remote Care. 2-4 bizhub PRO 951
