Explain Various Security Modes Present In Oracle Access Manager?

1.	Explain Various Security Modes Present In Oracle Access Manager?
Answer» Open: Allows unencrypted communication. In Open mode, there is no authentication or encryption between the AccessGate and Access Server. The AccessGate does not ask for proof of the Access Server’s identity and the Access Server accepts connections from all AccessGates. Similarly, Identity Server does not require proof of identity from WebPass. Simple: Supports encryption by ORACLE. In Simple mode COMMUNICATIONS between Web clients (WebPass and Identity Server, Policy Manager and WebPass, and Access Server and WebGate are encrypted using TLS v1. In both Simple and Cert mode, Oracle Access Manager components use X.509 digital certificates only. This INCLUDES Cert Authentication between WebGates and the Access Server where the standard cert-decode plug-in decodes the certificate and passes certificate information to the standard credential_mapping authentication plug-in. For each public key there exists a corresponding private key that Oracle Access Manager stores in the aaa_key.pem file for the Access Server (or ois_key.pem for Identity Server). Cert: Requires a third-party certificate. Use Cert (SSL) mode if you have an internal Certificate Authority (CA) for processing server certificates. In Cert mode, communication between WebGate and Access Server, and Identity Server and WebPass are encrypted using Transport LAYER Security, RFC 2246 (TLS v1).
