Changing an address space

For the added address spaces, you can edit the names, text descriptions, and rule settings. You cannot edit any of these for the Default address space, however.

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

When managing the rule settings of an address space, you must take into account the relations this address space has with addresses that are specified in application objects: devices, risks, rules, events, and other objects. If editing rule settings of an address space severs the relations of this address space with addresses, the application automatically deletes such addresses. This can lead to the deletion of the objects themselves (for example, devices) if these objects do not have any other addresses.

Only users with the Senior security officer role can edit the names, text descriptions, and rule settings of address spaces.

To edit the name, text description, or rule settings of an address space:

1. Use the web interface to connect to the Central Node with the Senior security officer role.
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 is displayed in the right part of the web interface window.

4. Depending on what you want, do the following:
   • Enter the name of the address space.

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

     The address space name must satisfy the following requirements:

     • Begins and ends with any character other than a space.
     • Contains up to 255 characters.
     • Does not reuse the name of another address space (case-insensitive).

     We recommend using address spaces 6–8 characters long or less. If the name is too long, the address information may not fit in the cells of some data tables (for example, in the table of devices).

   • Enter a description for the address space.
   • Manage the settings of address space rules.
   • If necessary, add and configure additional address space rules by clicking Add rule 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 settings are specified, or if some settings are invalid.

6. In the prompt window, confirm the changes of address space settings.
