Information security risk assessment refers to the process of analyzing the asset value, potential threats, weak links and protective measures of information systems with reference to risk assessment standards and management norms, judging the probability of security incidents and possible losses, and proposing risk management measures. The application of risk assessment to IT field is the risk assessment of information security.
Risk assessment has gradually changed from simple technical operations such as vulnerability scanning, manual auditing and penetration testing to methods such as BS7799, ISO 17799, and the national standard "Information System Security Level Assessment Criteria", which fully embodies the comprehensive method and operation mode of information security risk assessment with assets as the starting point, threats as the triggering factor and loopholes in technology/management/operation as the inducement.
Risk assessment is the basis of risk management, which depends on the results of risk assessment to determine the follow-up risk control and audit approval activities, so that organizations can accurately "locate" the strategies, practices and tools of risk management. Therefore, the focus of safety activities will be on important issues, and reasonable and applicable safety countermeasures will be selected.
