Version 6.1 

LOYTEC electronics GmbH 

 

15 Security Hardening Guide 

This guide contains security-relevant information for operating the product on IT networks. 
The  information  refers  to  the  firmware  version  and  the  instructions  found  in  the  previous 
chapters of this User Manual. 

15.1 Installation Instructions 

Install the device over the Web interface: 

 

Set up the basic device functions and protocol settings as described in Section 3.2 and 
6.2. 

 

Disable the FTP, and Telnet servers in the IP port configuration as described in Section 
6.2.4. 

Connect a serial console cable: 

 

Connect to the console as described in Section 5.1. 

 

Go to menu [3] system configuration. 

 

Disable the Web server in option [9]. 

 

Save the settings by hitting [x] for exit and save. 

15.2 Firmware 

The  device  is  equipped  with  one  piece  of  software.  This  is  the  firmware  image  and  its 
related  firmware  version.  The  firmware  is  distributed  as  a  downloadable  file.  The  device 
can  be  upgraded  by  placing  the  firmware  image  onto  the  device  using  the  procedure 
described in Chapter 12. 

There  exists  exactly  one  firmware  image  for  all  L-IP  models.  The  firmware  has  built-in 
auto-detection of the fieldbus ports the device is equipped with. It adds virtual routers to an 
internal  channel.  For  the  function  of  the  device  on  the  IP  side  this  makes  absolutely  no 
difference, as the IP connection is also tapped on to this internal channel. 

15.3 Ports 

This Section lists all ports, which may be used by the device. The ports are default settings 
for their respective services. If not stated otherwise, the ports can be changed. 

Required Ports:
