Re: network printers

[Sean Peterson <mrpeterson () theunixman com>]

To get an idea of the vulnerability of printers, I looked at "Hacking 
Network Printers" at  
http://www.irongeek.com/i.php?page=security/networkprinterhacking

Some manufacturers have documented basic security procedures, for 
example "HP Jetdirect Print Servers - Making HP Jetdirect Print Servers 
Secure on a Network" at 
http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=bpj05999

If you allow clients to print directly to the device via IP, then 
deploying a host with SysLog and  configuring the print devices to 
record their errors to the syslog host helps tremendously with diagnosis 
and problem analysis.

Hope this helps and if you come across any more detailed procedures, 
please post them on the list.
