This chapter describes how to set up security for image data you submit to NBIA.

Topics in this chapter include:

Data Security Overview

The User Authorization Tool in NBIA enables NBIA administrators to authorize users access to submitted image data. Administrators create protection group(s) and then assign protection elements to limit access and visibility of the image data. NBIA creates protection elements automatically based on image collection and site(s) of submitted data. Once the protections groups are set up, a user can be assigned to protection group(s) with the associated role(s). With the protection group/role combination, a user can only access the protection group data in the way specified by the role.

For example, user JoanSmith can access NCIA Mouse Astrocytoma as role CURATOR, but JohnJones can only access NCIA Mouse Astrocytoma as role READER.

Accessing the User Authorization Tool

To access the User Authorization Tool, you must be an NBIA administrator. Documentation about how to use the User Authorization Tool is in the NBIA Administrator's Guide.

  2. Select Administration > User Authorization.
    The User Authorization Tool window appears with the User, Protection Group, and User Authorization tabs.

Tip

You must be an NBIA administrator to use the User Authorization Tool.

Managing Users

Tip

Do to caching of user permissions it can take up to an hour for user changes to be reflected throughout the system.

Once a user submits data, an administrator adds the user to NBIA. The administrator must create the user in LDAP to manage data access privileges.

What to do if the user is not in LDAP

Contact Application Support to request that they add a user to LDAP.

Managing users involves:

  6. To activate the user, select Active Status. To deactivate the user in NBIA, clear Active Status.

  7. Click Save button to save the changes.
    The user is added to NBIA and the table on the User tab.

Managing Protection Groups

An NBIA administrator uses the Protection Group tab to add protection groups and assign protection elements to limit data access and visibility by image collection and site(s).

Managing protection groups involves:

Adding a Protection Group

    Do not use special characters such as # or \ in group names.

    Protection Group Description

    Add a description (optional).

  2. Click Save button to save the changes.
    The protection group is added to the table.

Associating Protection Elements with a Protection Group

Once you create the necessary protection group(s), assigning the associated protection element(s) is the beginning of setting up security for a collection's visibility in NBIA. The protection element identifies the collection, as well as the site, associated with the data.

Data Access and Protection Elements

If the protection element is set to Public, a user can be assigned the Public role and have access. For limited access to the data, assign a user to a protection group and a role that allows the user data access.

To associate a protection element with a protection group

  1. On the Protection Group tab, find the protection group.
  2. Click Add button in the Assign Protection Element column.
    The Add Protection Element(s) to Protection Group window appears.
    Add Protection Element(s) to Protection Group window

  3. Click Available Protection Elements.

  4. Select the elements to be associated with the protection group.

    Narrowing a List

    To narrow a list, type the name or part of the name next to the magnifying glass icon (Magnifying glass icon).

  5. Click Add button to save the changes.

  6. The Associated Protection Element(s) column lists the elements that you added.

    In the following example protection element, NCIA.SportInjury//ACL

    • NCIA.SportInjury is the collection.

    • ACL is the site.

      Multiple Sites

      If there are multiple sites for a collection, you might want to create a protection group for each site. This process would grant access to verify submissions per site.

Removing Protection Elements from a Protection Group

  1. On the Protection Group tab, find the protection group.
  2. Click Remove button in the Remove Protection Element(s) column.
    The Remove Protection Element(s) from Protection Group window appears.
    Remove Protection Element(s) from Protection Groups window
    The Protection Group Name cannot be changed.

Finding a Protection Group

On the Protection Group tab, you can perform a global search or a column search both described in the following table.

 You can perform both searching techniques to further filter a list, but do not forget to clear the search boxes to expand the list.

Type of SearchPerforming a Search
Global Search

You can search for a term or part of a term in all the protection group columns in the table. All protection groups with the characters you entered are returned.

In the following example, a Global Search of colonography finds protection groups with the word in the Protection Group name and the Associated Protection Elements.

Global search of a protection group
Column Search

You can also find protection groups in the table by adding a term to a column header or more than one column header to further narrow the list.

In the following example, bbb in the Protection Group column and demo in the Description column, displays two results.

Adding Protection Groups and Assigning Roles

An NBIA administrator creates protection groups to limit data access and visibility by image collection and site(s). Administrators add users to protection groups and can then further manage their access by assigning them one or more roles. Users can only access the protection group data in the way that the role specifies.

For example, John Smith needs to be a curator within the Mouse Astrocytoma protection group, so user johnsmith is assigned to protection group NBIA Mouse Astrocytoma with the role of CURATOR.

Topics in this section include:

Adding a Protection Group

  1. Select Admin > User Authentication Tool.
  2. Select the Protection Group tab.
  3. Scroll down to the bottom of the page and click Add Protection Group button.
    The Protection Group Details window appears.
    Protection Group Details window

  4. Enter a name for the new group and optionally, a description.

    No Special Characters

    Do not use special characters such as # or \ in group names.

  5. Click Save button.
    The protection group appears on the Protection Group tab.
