Adding a subnet

To add a subnet:

1. Connect to the Kaspersky Industrial CyberSecurity for Networks Server through the web interface using the Administrator account.
2. Select the Assets section.
3. On the Address spaces tab, expand the block containing information about the address space in which you want to add a subnet.
4. In the header of the Subnets block, click the icon.

   The details area appears in the right part of the web interface window.

5. In the Subnet field, enter the subnet address in CIDR format: <base address of subnet>/<number of bits in mask>.
6. In the Type drop-down list, select the type of subnet according to its purpose.
7. Set the following toggle buttons to the necessary positions:
   • Ignore MAC addresses for NIC rules – enables and disables the mode for skipping detected MAC addresses when creating allow rules based on Network Integrity Control technology.

     If this option is enabled, the MAC addresses detected together with IP addresses from the subnet will not be added to Network Integrity Control rules in learning mode.

   • Automatically add subnets – enables and disables automatic addition of nested subnets according to data received from EPP applications.

     If this mode is enabled, the application adds nested subnets within this subnet based on data received from EPP applications. By default, the type selected for the current subnet is indicated for these nested subnets.

8. Click Save.

The list of subnets will show the new subnet at its corresponding level of the hierarchy within the tree.
