Secure Printing in Wireless LANs

Important Security Features for Attaching Network Printers to Wireless Networks
In wireless networks data are transfered via radio in the air. As a consequence e.cient security measures are especially important to protect these data. Print documents often contain confidential and sensitive data. This is why network printers should be equipped for a safe connection to wireless LAN. WLAN print servers should naturally support the latest WLAN encryption standards as well as safe methods of authentication (IEEE 802.1X).

USB Device Server

Accessing USB Devices via the Network
The USB (Universal Serial Bus) is a simple connection standard used to attach a great number of diverse peripheral devices to PCs and notebooks. Until recently, technical reasons allowed only the connection of USB devices locally or via USB switch.

Using non-network-enabled USB Output Devices (GDI Printers, Multifunctional Peripherals, Copiers) via the Network
Until now so-called GDI printers – i.e. low-priced USB printers with the Windows interface GDI (Graphic Device Interface) – or non-network-enabled multifunctional peripherals (MFP) could only be deployed locally as single workstation printers because they are not equipped with a processor, have very little memory at their disposal, and rely on the resources of a Windows PC for processing print data. Also, such USB output devices communicate exclusively via proprietary printer languages. For these reasons they could not be shared in a network. The new software release 10.2.x by SEH includes the feature USB-to-Network (UTN). This allows users to access GDI printers, non-network-enabled copiers, and MFPs via the net just like a fully developed network printer. This white paper explains how using the USB print servers PS03a, PS23a, PS34a, PS34a-PoE, and PS54a-G with UTN makes it possible to access such output devices in a Windows network independent of make and model.

Properties, Applications, Technological Potential
As a rule, there is no reference to IPv6 which is not accompanied by the mention of the IP address completion. About 75 per cent of the addresses provided by the currently predominant internet protocol IPv4 have already been assigned. Experts warn that the reserves might run dry between 2009 and 2013. The regional registries for IP addresses therefore are already preparing for this scenario and advising ISPs (Internet Service Providers) to begin migrating to IPv6. This protocol offers an unimaginably huge address space, solving the problem of IP address depletion once and for all. However, that is not all IPv6 has to offer. The US government plans to complete the migration of all of its networks by August 2008, arguing that due to integrated security mechanisms and additional functionalities IPv6 is the smarter package. This white paper discusses the new network protocol IPv6 and looks at its implications for network printing. The latest SEH print server series "PS" enables network printing in IPv6 networks.

Security Risks in Network Printing

Solutions from the PC to the printed document
In every enterprise and organization there are confidential data and documents which have to be protected from unauthorized access. In IT departments security measures such as the quality of passwords, SSL/TLS or VPN connections ensure the security of sensitive or critical data. Moreover, current data protection acts require institutions and enterprises to protect personal data from unauthorized access.

Consequently there is a growing awareness that secure network printing should be part of any solid IT security policy. When confidential data is sent through the network in clear text, the above mentioned security measures will be futile. This White Paper describes the security risks which a print job is likely to encounter on its way from the user’s workstation to the collection tray of the printer, and proposes solutions.
