Changing Port Numbers
Ports  serve as endpoints for  communicating with other devices.  Typically, conventional port numbers  are  used for  major protocols,  but
devices that  use these port numbers  are  vulnerable  to  attacks  because  these port numbers  are  well-known. To enhance security,  your
Network Administrator may  change the  port numbers. When  a port number has been changed, the  new number must be shared  with the
communicating devices,  such as computers and  servers. Specify...

Setting a Proxy
A proxy (or HTTP proxy server) refers to  a computer  or software  that  carries out  HTTP communication for  other devices,  especially  when
communicating with resources  outside the  network, such as when browsing Web sites. The client  devices connect to  the  outside ne twork
through the  proxy server, and  do not  communicate directly  to  the  resources  outside.  Setting a proxy not  only facilitates manage ment  of
traffic between  in-house and  outside networks but also...

Restricting Access to Address Book and Sending Functions (MF8580Cdw /
MF8550Cdn / MF8540Cdn / MF8280Cw Only)
Some  cases of information  leakage can be prevented  by limiting the  available fax  and  e-mail destinations to  those registered in the
Address Book or LDAP servers, or by setting a PIN  for  the  Address Book so that  unauthorized users  cannot  add  or edit Address Book
entries. You  can also  avoid  sending documents to  unintended  recipients  if  the  machine is  set to  ask  you...

Setting a PIN for Address Book
The Address Book can be set to  require users  to  enter a PIN  in order to  add  new entries to  the  Address Book
or edit existing entries. Setting a PIN  to  the  Address Book can reduce  the  risk of documents being sent to
unintended  recipients  because  changes to  the  Address Book can only be made  by users  who know the  PIN.

Limiting Available Destinations
By limiting fax  numbers  that  can be specified when sending documents to  those already  registered in the
Address Book,  those previously used, or those searchable  from the  LDAP servers, you can reduce  the
possibility of specifying  incorrect  destinations and  prevent  users  from leaking information. When  this function
is  enabled,  the  machine prohibits users  from entering  destinations using the  numeric keys, adding new entries
to  the  Address Book,...
