NetBackup and NetBackup Appliances Hardening Guide

Using network access control

You can use the network access control feature to control which IP addresses are allowed to access the appliance. Use HTTPS access control to control which IP addresses can access the Flex Appliance Console or the APIs through HTTPS. Use SSH access control to control which IP addresses can access the Flex Appliance Shell through SSH.

To configure or edit network access control

  1. Sign in to the Flex Appliance Console as a security administrator and click the gear icon in the upper-right corner of the page, then click Network Access Control.
  2. Depending on which service you want to configure, click Configure or Edit under HTTPS access control or SSH access control.
  3. Follow the prompts to add the IP addresses or subnets that you want to have access to the appliance. Any IP addresses that are not included in the allowed list cannot access the appliance.

    Note the following information:

    • The IP protocol of the addresses in the allowed list must match the protocol of the appliance.

    • Subnets must be entered in CIDR notation. For example, 1.1.1.0/24.

    • If you use the Dynamic Host Configuration Protocol (DHCP), add subnets instead of IP addresses.

    • For HTTPS access control, you must include your current IP address in the allowed list. It can be entered by itself or as part of a subnet.

    • For SSH access control, you can leave the allowed list empty to block all SSH access.

To disable or enable network access control

  1. Sign in to the Flex Appliance Console as a security administrator and click the gear icon in the upper-right corner of the page, then click Network Access Control.
  2. Depending on which service you want to disable or enable, click Edit under HTTPS access control or SSH access control.
  3. Deselect or select the check box next to Enable HTTPS access control or Enable SSH access control.
