Preface
Security recommendations
To prevent unauthorized access, observe the following security recommendations when
working with the optical readers and WBM (Web Based Management).
General
● Check regularly that the device complies with these recommendations and/or other
internal security policies.
● Evaluate your plant as a whole in terms of security. Use a cell protection concept with
suitable products.
● Do not connect the device directly to the Internet. Operate the device within a protected
network area.
Physical access
● Restrict physical access to the device to qualified personnel.
● Lock unused hardware ports on the device. Unused ports can be used to access the
system without authorization.
Software (security functions)
● Keep the software up to date. Keep yourself informed regularly about safety updates for
the product.

● Activate only protocols that you actually need to use the device.
● Limit access to the device using a firewall or rules in an access control list (ACL).
● The configuration files are available in XML format for simple use. Make sure that the
configuration files outside the device are suitably protected. You can, for example,
encrypt the files, store them at a safe location and transfer them only via secure
communications channels.
● We recommend that you disable the "CONNECT" function after initial commissioning.
● The functions for archiving as well as the remote functions (MMI) may only be activated in
networks protected by a firewall.
