Ricoh Aficio Common Security Features Guide Data Encryption As mission critical data traverses the network it is possible for the knowledgeable hacker to intercept raw data streams, files, and passwords. The advent of wireless network technology, while increasing the convenience of surfing and printing for millions, also leaves networks vulnerable to attack from intruders armed with wireless laptops via any access points within range. Without protection, intelligible information can easily be stolen, or modified/falsified and re-inserted back into the network. Ricoh Aficio devices are equipped with the following encryption capabilities to reduce these risks. 128-bit SSL/TLS (Secure Socket Layer/Transport Layer Security) Encryption & the Network Data Protection Unit Once a user has been granted access to the device through an active authentication mechanism, Ricoh devices offer another level of security through password and data encryption capabilities. By scrambling data prior to sending it over the LAN for output or storage, it becomes impossible for hackers to decipher, and subsequently gain access to tamper or steal documents under false pretenses. A series of communications takes place between the sending PC and the printer or MFP so that passwords and/or data can be encrypted prior to sending, and decrypted once they arrive at the device. To enable this function, the Ricoh device must be equipped with the Network Data Protection Unit, and the SSL Certificate must be pre-installed. The Network Data Protection Unit (NDPU) is available as an option on some devices and is offered standard on others. The NDPU is installed in the main unit controller and employs 128-bit strength encryption to protect data. It works by dividing data sent from a PC over network lines into blocks of scrambled bits. This function can be activated when data is to be sent via the hardwired Ethernet interface, or the IEEE 802.11b Wireless LAN interface. 11
