#### 6.7.3 Configuring Security services for PolyORB

PolyORB provides support for some elements of the CORBA Security mechanisms. This sections lists the corresponding configuration parameters.

##### 6.7.3.1 Supported mechasnisms

PolyORB provides support for the following security mechanisms:

1. SSL/TLS protected transport;
2. GSSUP (user/password) authentication mechanism;
3. identity assertion and backward trust evaluation.

##### 6.7.3.2 Compile-time configuration

To enable security support, applications must `with' one of the predefined setup packages:

1. `PolyORB.Setup.Secure_Client` - for client side support only;
2. `PolyORB.Setup.Secure_Server` - for both client and server side support.

##### 6.7.3.3 Run-time configuration

   This section details the configuration parameters for capsule configuration.

2. Credentials configuration

   This section details configuration parameters for defining a program's credentials. Depending on the mechanisms used for the transport and authentication layers, the credentials configuration section may define configuration only for one transport mechanism and/or one authentication mechanism.
