Changing an address space

You can change the names, text descriptions, and settings of address space rules for added address spaces. These changes cannot be made to the Default address space.

You can also generate lists of subnets for any address spaces (including the list of subnets of the Default address space).

When changing the settings of an address space rule, you must take into account the established links between this address space and the addresses that are indicated in application objects, including devices, risks, rules, events, and other objects. If changing the settings in address space rules results in the deletion of links between this address space and addresses, the application automatically deletes these addresses. This could lead to the deletion of application objects (such as devices) if these objects have no other remaining addresses.

Only users with the Administrator role can change the names, text descriptions, and settings of address space rules.

To change the name, text description, or settings of address space rules:

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, click the icon in the block containing information about the relevant address space.

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

4. Depending on the necessary result, perform the following actions:
   • Enter the name of the address space.

     You can use letters, numerals, a space, and the following special characters: ! @ # № $ % ^ & ( ) [ ] { } ' , . - _.

     The address space name must meet the following requirements:

     • Must begin and end with any permitted character except a space.
     • Must contain 255 characters or less.
     • Must not match the name of another address space (not case-sensitive).

     It is recommended to set an address space name that is no more than 6–8 characters long. If the name contains more characters, the address information may not be fully displayed in the cells of some data tables (for example, in the devices table).

   • Enter a description of the address space.
   • Configure the settings of address space rules.
   • If necessary, add and configure additional address space rules by clicking the Add rule button or delete any unnecessary rules by using the icons.

     The total number of rules in an address space cannot exceed 10.

5. Click Save.

   This button is unavailable if not all required values are specified or if there are invalid values in the settings.

6. In the prompt window, confirm the changed address space settings.
