System Vulnerabilities
Response Point runs on your office LAN, and your organization may have a wireless LAN. While convenient and popular,
the security features in many wireless default implementations may not be adequate for your needs. Consider whether
your LAN security configuration, especially your wireless LAN security configuration, is correct for your business.
Firewall Issues
It’s a good idea to use firewalls to help protect your office LAN. A firewall blocks requests or communication attempts
from any unspecified programs.
If you use a third-party firewall to provide security, instead of the default Windows Firewall, Assistant and Administrator
may not be able communicate with the base unit. To avoid this problem, create firewall exceptions in your firewall program
for Administrator and Assistant. A firewall exception allows selected programs to connect with your computer.
If you are using a third-party firewall, refer to its documentation for instructions on creating firewall exceptions.
Security Certificates
When you first log on to Administrator and connect to a base unit, you are asked to establish a security relationship
between the base unit and the computer running Administrator.
If you proceed to establish that security relationship, the base unit copies a certificate (a digital document) to the
computer running Administrator. Once the two have the same certificate information, your computer automatically trusts
that the base unit is legitimate.
Security certificates are put on the base unit when manufactured and have a 15-year expiration date. If you think you’re
near the 15-year limit, contact the manufacturer’s customer support service.
Occasionally, when you log on, you might get a security error, which won’t allow you to connect to a base unit. This can
occur if the certificate exchange has been corrupted, for example. In this case, try connecting again, or restart the base
unit so that the certificate can be reinitialized. If you still get an error, a program or other device on the LAN might be
trying to fool you or intercept your base unit data. You will see explanatory messages when these conditions occur.
