National assets such as transportation networks, large manufacturing, business and health facilities, power generation, and distribution networks are critical infrastructures. The cyber threats to these infrastructures have increasingly become more sophisticated, extensive and numerous. Cyber security conventional measures have proved useful in the past but increasing sophistication of attacks dictates the need for newer measures. The autonomic computing paradigm mimics the autonomic nervous system and is promising to meet the latest challenges in the cyber threat landscape. This paper provides a brief review of autonomic computing applications for SCADA systems and proposes architecture for cyber security.

Single sign-on (SSO) is an identity management technique that provides users the ability to use multiple Web services with one set of credentials. However, when the authentication server is down or unavailable, users cannot access Web services, even if the services are operating normally. Therefore, enabling continuous use is important in single sign on. In this paper, we present security framework to overcome credential problems of accessing multiple web application. We explain system functionality with authorization and Authentication. We consider these methods from the viewpoint of continuity, security and efficiency makes the framework highly secure.
