IT Risk Management
IT Risk Management is the application of risk management methods to information technology in order to manage IT risk.
The establishment, maintenance and continuous update of an Information Security Management System (ISMS) provide a strong indication that a company is using a systematic approach for the identification, assessment and management of information security risks.
The process of risk management is an ongoing iterative process. It must be repeated indefinitely. The business environment is constantly changing and new threats and vulnerabilities emerge every day. The choice of countermeasures (controls) used to manage risks must strike a balance between productivity, cost, effectiveness of the countermeasure, and the value of the informational asset being protected.
