Health State Requirements - Barracuda Networks NG Network Access Client SP4 Administrator's Manual

If the client fails during a specific time it's state is changed to "Unhealthy". In other terms the client is
put into quarantine. This means that the client enables it's latest quarantine rule set.
On the Barracuda NG Firewall the proper state is propagated to the firewall engine where limited
access can therefore be enforced.
Even the quarantine rule set must at least enable the client to connect to the Access Control Service, to the
Microsoft active directory, and to the remediation servers. Depending on the company's infrastructure, more
connections should be available to restore the client's health state to "Healthy" again.

Health State Requirements

The following list provides an overview of the available Health State requirements. Failing a health
state requirement can either trigger automatic "self-remediation" or can require a manual action of the
user.
The desired behavior is configurable since some versions of Antivirus- or Antispyware do not fully
support auto-remediation. In case of manual action the user is informed about the required actions by
the Barracuda NG Access Monitor.
A list of all supported AV and AS engines is available via
(see also 2.4.8 Support Chart, page 40).

Client Clients to recognize and activate AV and AS products.
