The semantic web aims to describe information in terms of welldefined vocabularies and comprehends both data and knowledge to cope with meaning of data. Advanced search engines are used to retrieve precise information out of these knowledge resources. The main challenge is not only retrieving data but also how to keep data safe and protected against any form of attacks. In this paper, we propose a security aware based model for semantic search engines. Our work aims to combine advances in information technology, such as cloud technology, while addressing security issues which threaten the integrity of information. In particular security gaps and countermeasures of the semantic web are identified. ISO/IEC security requirements for the protection of personally identifiable information (PII) are presented to cover security vulnerabilities of the proposed model. Finally, the feasibility of our proposed model is checked against the N2Sky use case, a multi-cloud knowledge information management system for the computational intelligence community.
