Typical Security Tasks

This section contains the typical security tasks you can perform with Oracle CEP Visualizer.

Visualizer is fairly self-explanatory, so not all tasks are discussed here, but rather, just those that are most common and typical and from which other similar tasks can be deduced.

This section describes the following topics:

 

Creating New Users

  1. Be sure you log on to Visualizer using an administration user.
  2. In the left pane, click the Domain > Security node, where Domain refers to the name of your Oracle CEP domain.
  3. In the right pane, click the User tab.
  4. Click the New User button at the bottom of the right pane.
  5. Enter the name of the new user and their password. Enter an optional description of the user.
  6. Click the groups to which the user belongs. You must assign a user to at least one group.
  7. Click OK.

 

Changing the Groups to Which a User is Assigned

If, after you have created a user, you want to change the groups to which it is assigned, follow these steps:

  1. Be sure you log on to Visualizer using an administration user.
  2. In the left pane, click the Domain > Security node, where Domain refers to the name of your Oracle CEP domain.
  3. In the right pane, click the User tab.
  4. In the Users table, check the box to the left of the name of the user that you want to modify.
  5. Click Modify User at the bottom of the pane.
  6. Optionally modify the description of the user.
  7. In the Groups table, check the groups to which the user belongs.
  8. Click OK.

 

Deleting a User

Although you cannot delete the default administrator user, which is the administrator user originally configured for the domain when it was created with the Configuration Wizard, you can delete other users you subsequently created.

  1. Be sure you log on to Visualizer using an administration user.
  2. In the left pane, click the Domain > Security node, where Domain refers to the name of your Oracle CEP domain.
  3. In the right pane, click the User tab.
  4. In the Users table, check the boxes to the left of the name of the users that you want to delete.
  5. Click Delete Users.

 

Changing the Password of a User

  1. Be sure you log on to Visualizer using an administration user.
  2. In the left pane, click the Domain > Security node, where Domain refers to the name of your Oracle CEP domain.
  3. In the right pane, click the User tab.
  4. In the Users table, check the box to the left of the name of the user whose password you want to change.
  5. Click Change Password at the bottom of the pane.
  6. Enter the new password, then enter it again to confirm it.
  7. Click OK.

 

Creating a New Group

Oracle CEP is configured by default with a set of groups that are in turn mapped to roles. See Viewing the SSL Configuration for a Server for details. This section describes how to create new groups.

  1. Be sure you log on to Visualizer using an administration user.
  2. In the left pane, click the Domain > Security node, where Domain refers to the name of your Oracle CEP domain.
  3. In the right pane, click the Group tab.
  4. Click the New Group button at the bottom of the pane.
  5. Enter the name of the group, along with a description.
  6. Click one or more roles to which the group maps. See Viewing the SSL Configuration for a Server for details about the roles.
  7. Click OK.

 

Modifying the Roles to Which a Group Maps

To change the roles to which a group maps after it has been created, follow these steps:

  1. Be sure you log on to Visualizer using an administration user.
  2. In the left pane, click the Domain > Security node, where Domain refers to the name of your Oracle CEP domain.
  3. In the right pane, click the Group tab.
  4. In the Groups table, click the box to the left of the name of the group that you want to modify.
  5. Click Modify Group at the bottom of the pane.
  6. Optionally modify the description of the group.
  7. In the Has Roles table, click the roles to which this group maps. You must click at least one group.
  8. Click OK.

 

Deleting a Group

You cannot delete the default groups that are automatically configured for Oracle CEP. You can, however, delete groups that you subsequently created.

  1. Be sure you log on to Visualizer using an administration user.
  2. In the left pane, click the Domain > Security node, where Domain refers to the name of your Oracle CEP domain.
  3. In the right pane, click the Group tab.
  4. In the Groups table, click the box to the left of the name of the group that you want to delete.
  5. Click Delete Group at the bottom of the pane.

 

Configuring Security for the HTTP Publish-Subscribe Channels

Using Visualizer, you can specify the roles that are allowed to publish to the HTTP publish-subscribe channels that are configured for the HTTP pub-sub server included in Oracle CEP.

  1. Be sure you log on to Visualizer using an administration user.
  2. In the left pane, click the Domain > Server > Services > Http Pub/Sub Server node, where Domain refers to the name of your Oracle CEP domain and Server refers to the name of the server instance.

    3. A table appears in the right pane with the list of HTTP pub-sub servers configured for Oracle CEP.

  3. In the right pane, click the name of the HTTP pub-sub server in the table. The default server is called pubsub.
  4. In the Channels table, click the name of the channel for which you want to configure security.
  5. In the Publish Roles table, select the roles that are allowed to publish messages to this channel. If you want to select more than one role, use the Ctrl key.
  6. Click Modify Channel at the bottom of the pane.

 

Viewing the SSL Configuration for a Server

You can only view the SSL configuration of your Oracle CEP server using Visualizer. To change the configuration, you must manually update the server’s config.xml file. For details, see Uing SSL to Secure Network Traffic.

To view the SSL configurion of your Oracle CEP server:

  1. In the left pane, click the Domain > Server node, where Domain refers to the name of your Oracle CEP domain and Server refers to the name of the server instance.
  2. In the right pane, click the SSL tab.
  3. In the left table, click the SSL configuration you want to view. The default configuration name is sslConfig.
  4. The right table displays particular SSL configuration options.
