Configuring the MFP

Administrative support
SNMPv3 authentication and encryption has three levels of support:
No authentication and no encryption
Authentication with no encryption
Authentication and encryption
Note:
The selected level serves as a minimum level of protection. The MFP negotiates with the SNMPv3 
requestor, and a higher level of protection may be agreed upon and used by both.

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 MFP and up to five hosts, 
using both IPv4 and IPv6. To configure IPSec through the EWS: 
1
Open a Web browser. In the address line, enter the IP address of the MFP being configured using the format: 
http://ip_address/.

IPSec
.
Two types of authentication are supported for 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. The certificate authority certificate must be installed. Each host must have its identifier in the 
Subject 
Alternate Name
 of the signed certificate.
Note:
After an MFP is configured for IPSec with a host, IPSec is required for any IP communication to take 
place.
