  This paper describes the background of smart information infrastructure and
the needs for smart grid information security. It introduces the conceptual
analysis to the methodology with the application of hermeneutic circle and
information security functional requirement identification. Information
security for the grid market cover matters includes automation and
communications industry that affects the operation of electric power systems
and the functioning of the utilities that manage them and its awareness of this
information infrastructure has become critical to the reliability of the power
system. Community benefits from of cost savings, flexibility and deployment
along with the establishment of wireless communications. However, concern
revolves around the security protections for easily accessible devices such as
the smart meter and the related communications hardware. On the other hand, the
changing points between traditional versus smart grid networking trend and the
information security importance on the communication field reflects the
criticality of grid information security functional requirement identification.
The goal of this paper is to identify the functional requirement and relate its
significance addresses to the consumer requirement of an information security
of a smart grid. Vulnerabilities may bring forth possibility for an attacker to
penetrate a network, make headway admission to control software, alter it to
load conditions that destabilize the grid in unpredictable ways. Focusing on
the grid information security functional requirement is stepping ahead in
developing consumer trust and satisfaction toward smart grid completeness.
