GeneXus Server KB Security Defaults is a subnode of the Security Node that lists all Groups and Users Knowledge Base permissions.
The elements of the list vary depending on whether the tab selected is the Groups or Users tab.
Each element of the Groups tab shows the Group name and the Knowledge Base Permissions.

On the other hand, each element of the Users tab shows the Username, Authentication type, and Knowledge Base Permissions.

Hovering over the name of a Server Group will display the 'Edit' option. By selecting this option, the user will be able to change the Groups Knowledge Bases default permissions.

Hovering over the name of a Server User will display the 'Edit' option. By selecting this option, the user will be able to change the User Knowledge Bases default permissions.
