HP Imaging and Printing Security Center 2.0 - Instant-On Security

FIGURE 11
Note: When IPv6 is enabled on the device, you will notice at least one IPv6 (AAAA) and
IPv4(A) DNS request per domain.
2. TCP Port 3329 is registered with the Internet Assigned Numbers Authority (IANA) and
specifically assigned to HP IPSC. See Figure 12. This port is dedicated to Instant-On
communication between the HP supported device and HP IPSC. Port 3329 is also
referred to as the hp-device-disc port. If the HP IPSC server windows firewall is in
use, ensure the firewall allows TCP Port 3329 communication in both directions.

3. At the HP IPSC server, create a security policy that best describes the conformance
requirements for devices on this network. This policy should be the most encompassing
policy relative to the mix of device models found in your corporate printing environment.
4. At the HP IPSC server, configure authentication requirements for communicating with
devices. Devices will attempt the highest level of authentication available. Choices are
No Authentication (true out-of-the box conditions) or Mutual Authentication
which leverages installed certificates.
5. Place a device which supports the DAA and is enabled, on the network.
