Supporting IPSec (Internet Protocol Security)
IP Security protocol provides authentication and encryption of communications at the network layer
allowing all application and network communications over the IP protocol to be secure. IPSec can be
set up between the printer and up to five hosts, using both IPv4 and IPv6. To configure IPSec

Shared Key Authentication-Any ASCII phrase shared among all the participating hosts.
This is the easiest way to configure when only a few hosts on the network use IPSec.

•
Certificate Authentication-Allows any hosts or subnet of hosts to authenticate for IPSec.
Each host must have a public/private key pair. Validate Peer Certificate is enabled by default,
requiring each host to have a signed certificate and the certificate authority certificate must
be installed. Each host must have its identifier in the Subject Alternate Name of the signed
certificate.

Note: After a device is configured for IPSec with a host, IPSec is required for any IP
communication to take place.
