As citizen of Information Age, we store and access everything. Virtually all aspects of Information are recorded and processed by a computer. This information is valuable resource and must be secured properly so that it does not fall into the wrong hands. The personal information stored on your computer is valuable enough to protect and security is an issue to everyone.(Bob, 2010).

Thefinding and conclusion on this research areto protect and lock the credential of the users in which we can trust the system; a lot of disturbancescould happenand bother for each users but sometimes we need toallow or disallow the information; the two choices werebe made of; such instances occurs; to open or close the system privately;Information Assurancecontains all the elements of information security (con-fidentiality) but also includes elements of availability, and integrity. Information as-assuranceprovides a view of information protectionthat includes defensive measuresin all three states —processing, storage, and transmission.Security holds both national and inter-national attention; frequently, one loses site thatour information security is more than physical. Global commerce relies on computersand an associated electronic infra-structure. E-commerce, business to business, Internet, and e-mail are just a few of the tools that have entered the vocabulary ofthe end user in the past decade. Many individuals would not know how to make theirlives work nor their enterprise profit-able without these tools. Consider how much would your life change if you no longer had access to the internet and its services Now, expand your thinking to include those other critical functions that are sup-ported by that same electronic infrastructure. Hospitals, airlines, power, food distribution, schools, libraries, agribusiness, manufacturingare a sample of critical in-formation infrastructure components that supporta modern economy and society.

These systems have become so complex that no one understands all their interactions. This complexity combined with tightlycoupled systems operations createsfragile critical systems. In these systems, failure of a single component may adverselyaffect the integrity, confidentiality, and availability of many critical systems.In addition,being fragile, they are brittle—they may break unexpectedly into ano recoverable state. Any national or international security effort cannot afford toplace the security of their economy and societyon the backs of fragile systems. Although languages and specifics may differby discipline, there is now general recognitionthat information technology securityis a core business process. Integralto establishing a core process is buildinga competent information technology securitywork force —a people-based counter measure. This security workforce facilitates both industry and government in establish ingintegrated information security systems relying on multidimensional approaches. The multidimensional approach dealswith technologies such as biometrics, crypto graphic systems, and smart cards; operationsissues such as HIPAA, trans-border data flows, procedures, software propertyrights, privacy, auditing, person-manufacturingare a sample of critical information infrastructure components that support a modern economy and society.

Finally, either our economyis directly or indirectly undertrack; this attack has been termed as network centric warfare. “The organizing principleof network-centric-warfare habitsantecedent in the dynamics of growth andcompetition that have emerged in the modern economy.Information assurance protects critical information infrastructures and provides for homeland security and risk assessment; as well as people development which goes beyond just Education and training into professional developmentand recognition through certification (Ajith, Johnson, Sugata,Lakhmi, 2005).
