Information Security Risk Management

Information Security Risk Management is the continuous process of identifying, assessing, and treating threats to an organization's information assets to bring risk to an acceptable level. This framework involves analyzing potential vulnerabilities, evaluating the likelihood of a threat exploiting them, and determining the potential impact on the confidentiality, integrity, and availability of data and systems. The ultimate goal is to enable an organization to make informed, cost-effective decisions to accept, mitigate, transfer, or avoid risk, thereby strategically allocating security resources to protect its most critical assets and align its cybersecurity posture with business objectives.
