Updating the Appliance

Proventia Network IPS G and GX Appliance User Guide
Consider using the X-Press Update Server under the following conditions:
● Large number of appliances. If you have deployed a large number of appliances, you
can save bandwidth. The appliances can request updates from one Update Server, as
opposed to using bandwidth to download the same updates for each appliance from
the ISS Download Center.
● Locked down environment. If you want to download updates in a more secure
environment and do not want every appliance to have Internet access for downloads,
the appliance can request updates from the Update Server. In this case, only the
Update Server requires the Internet connection.
See the SiteProtector documentation or online help for information about configuring the
X-Press Update Server.
Virtual Patch
technology
Automatic security updates come from ISS X-Force using Virtual Patch technology. The
Virtual Patch process protects systems against attack during the interval between
discovery of a vulnerability and the manual application of a security patch.
The Virtual Patch is an important component of ISS's Dynamic Threat Protection platform.
By combining the functionality of vulnerability detection, intrusion protection,
management, and advanced correlation tools, you can have a unified view of system-wide
intrusion protection capabilities to protect against known and unknown threats.
