what are the components of information security

A security policy is a concise statement, by those responsible for a system (e.g., senior management), of information values, protection responsibilities, and organizational commitment. These include the systems and hardware that use, store, and transmit that information. The interpretation of an aspect in a given environment is dictated by the needs of the individuals, customs, and laws of the particular organization. In order to protect information, a solid, comprehensive application security framework is needed for analysis and improvement. IT security is a set of cybersecurity strategies that prevents unauthorized access to organizational assets such as computers, networks, and data. Considering the definition, utility refers to something that is useful or designed for use. Information Security Policy and Guidance Information security policy is an aggregate of directives, rules, and practices that prescribes how an organization manages, protects, and distributes information. A better form of authentication is biometrics, because it depends on the user’s presence and biological features (retina or fingerprints). The user must prove access rights and identity. These five components integrate to perform input, process, output, feedback and control. Proof of authentic data and data origination can be obtained by using a data hash. To preserve utility of information, you should require mandatory backup copies of all critical information and should control the use of protective mechanisms such as cryptography. As it pertains to information security, confidentially is the protection of information from unauthorized people and processes. … Information security plays a very important role in maintaining the security in different types of drastic conditions such as the errors of the integrity.

Defining confidentiality in terms of computer systems means allowing authorized users to access sensitive and protected information. The equipment includes all peripherals, including servers, routers, monitors, printers and storage devices. Information security risk management involves assessing possible risk and taking steps to mitigate it, as well as monitoring the result. Hardware consists of input/output device, processor, operating system and media devices. Information Security is basically the practice of preventing unauthorized access, use, disclosure, disruption, modification, inspection, recording or destruction of information. Confidentiality can be ensured by using role-based security methods to ensure user or viewer authorization (data access levels may be assigned to a specific department) or access controls that ensure user actions remain within their roles (for example, define user to read but not write data). To implement and maintain an effective information security awareness and training program, several “best practices” and building blocks should be used. Network consists of hubs, communication media and network devices. The elements are unique and independent and often require different security controls.
