Configuring Security for Oracle CEP 10-3
Once you have configured the security provider, you can start using Oracle CEP Visualizer to add new users, assign them to groups, and map groups to roles. See
Section 10.1.3, Users, Groups, and Roles .
10.1.3 Users, Groups, and Roles
Oracle CEP uses role-based authorization control to secure the Oracle CEP Visualizer and the wlevs.Admin command-line utility. There are a variety of default
out-of-the-box security groups. You can add users to different groups to give them the different roles.
Administrators who use Oracle CEP Visualizer, wlevs.Admin, or any custom administration application that uses JMX to connect to an Oracle CEP instance use
role-based authorization to gain access.
You can also use role-based authorization to control access to the HTTP publish-subscribe server.
There are two types of role:
■
Application roles: application roles grant users the permission to access various Oracle CQL applications deployed to the Oracle CEP server. You can create
application roles and associate them with the task roles that Oracle CEP provides.
By default, administrator users can access any application and non-administration users cannot access any applications. Before a none-administration user can access
an application, an administration user must grant the user the associated application role.
■
Task roles: task roles grant users the permission to perform various tasks with the applications their application role authorizes them to access. Oracle CEP provides
the default task roles that Table 10–1
describes. Users that successfully authenticate themselves when using Oracle CEP Visualizer or
wlevs.Admin are assigned roles based on their group membership, and then subsequent access to administrative functions is restricted according to the roles held
by the user. Anonymous users non-authenticated users will not have any access to the Oracle CEP Visualizer or wlevs.Admin.
When an administrator uses the Configuration Wizard to create a new domain, they enter an administrator user that will be part of the wlevsAdministrators group. By
default, this information is stored in a file-based provider filestore. The password is hashed using the SHA-256 algorithm. The default administrator user is named wlevs
with password wlevs.
Table 10–1 describes the default Oracle CEP tasks roles available right after the
creation of a new domain, as well as the name of the groups that are assigned to these roles.

10-4 Oracle Complex Event Processing Administrators Guide
Once the domain has been created, the administrator can use Oracle CEP Visualizer to create a group and associate it with one or more roles: each role grants access to an
application. When you assign a user to a group, the roles you associate with the group give the user the privileges to access those applications.

10.1.4 SSL
Oracle CEP provides one-way Secure Sockets Layer SSL to secure network traffic between Oracle CEP Visualizer and Oracle CEP server instances, between the Oracle
CEP server instances of a multi-server domain, and between the wlevs.Admin command-line utility and Oracle CEP server instances.
You can configure Oracle CEP to use a Federal Information Processing Standards FIPS-certified pseudo-random number generator for SSL.
