Protecting information by mitigating risk

Information security, sometimes shortened to infosec, is the practice of protecting information by mitigating information risks. It is part of information risk management. It typically involves preventing or reducing the probability of unauthorized or inappropriate access to data or the unlawful use, disclosure, disruption, deletion, corruption, modification, inspection, recording, or devaluation of information. It also involves actions intended to reduce the adverse impacts of such incidents. Protected information may take any form, e.g., electronic or physical, tangible, or intangible. Information security's primary focus is the balanced protection of data confidentiality, integrity, and availability while maintaining a focus on efficient policy implementation, all without hampering organization productivity. This is largely achieved through a structured risk management process that involves:Identifying information and related assets, plus potential threats, vulnerabilities, and impacts; Evaluating the risks Deciding how to address or treat the risks, i.e., to avoid, mitigate, share, or accept them Where risk mitigation is required, selecting or designing appropriate security controls and implementing them Monitoring the activities and making adjustments as necessary to address any issues, changes, or improvement opportunities
