Access Control

The administrator can limit devices or protocols that can be connected to the machine to avoid unintended access.

Also, the administrator can select a security level at which to enable or disable a protocol and to configure the port status.

Limiting the IP addresses from which devices can access the machine (access control)

For example, when specifying the range of IP address from "192.168.15.1" to "192.168.15.99", the machine cannot be accessed from IP addresses in the range from 192.168.15.100 to 255.

Illustration of access control

Disabling unused protocols

The protocol setting can be changed on the control panel, in Web Image Monitor, or by using other setting methods. The protocols that can be configured vary depending on the method. Confirm the protocol to configure in Protocol Setting Method List and follow the instruction.

Illustration of access control

Specifying the security level

You can select from among four security levels combining different protocols, ports, and encryption algorithms. Confirm the description of each level in Security Level Setting List.

You can customize the security setting based on the selected level setting to suit your condition.

Limiting the IP Addresses from which Devices Can Access the Machine

Specify the range of the IP address that can access the machine by using Web Image Monitor.

Important

  • You can limit access from the following protocols.

    • LPR, RCP/RSH, FTP, Bonjour, SMB, WSD (Device), WSD (Printer), WSD (Scanner)/DSM, IPP, DIPRINT, RHPP, snmp, telnet, NBT

  • The machine also limits access from Web Image Monitor.

1Log in to the machine as the network administrator from Web Image Monitor.

Logging in to the Machine as the Administrator

2Click [Configuration] on the [Device Management] menu.

3Click [Access Control] in the [Security] category.

4In "Access Control", click [Active] and specify the range of IP addresses that have access to the machine.

  • To specify an IPv4 address, enter a range that has access to the machine in [Access Control Range].

  • To specify an IPv6 address, select [Range] or [Mask] in "Access Control Range", and then enter a range that has access to the machine.

5Click [OK].

6Log out of the machine, and then exit the Web browser.

Security Level Setting List

You can configure security level settings using the control panel or Web Image Monitor. You can select the following security levels:

Important

  • With some utilities, communication or login may fail depending on the network security level.

  • Level 0

    Users can use all features without restriction. Select this when you have no information that needs to be protected from external threats.

  • Level 1

    Level 1 is suitable for a connection in an office.

  • FIPS 140

    FIPS 140 provides a security strength intermediate between "Level 1" and "Level 2".

    You can only use codes recommended by the U.S. government as its coding/authentication algorithm. Settings other than the algorithm are the same as "Level 2".

  • Level 2

    Level 2 is the maximum security that is available in the machine. Select it to protect extremely important information.

For details about the security level settings, see the following list: You can change the setting for a particular function according to the use condition of the machine.
