What is the main reason for performing risk assessment on a continuous basis?

Performing risk assessments on a continuous basis is essential mainly because the risk environment is constantly changing. This includes shifts in threats, vulnerabilities, and the overall context in which an organization operates. As businesses evolve, new technologies and processes may introduce unfamiliar risks, while existing risks can amplify or diminish based on various internal and external factors, including market dynamics, regulatory requirements, and technological advancements.

Continuous risk assessment allows organizations to remain agile and reactive to these changes, ensuring that security controls are appropriately aligned with the current risk landscape. By regularly reevaluating risks, organizations can ensure that their security posture remains strong and is tailored to tackle the most pressing threats.

While justifying the security budget, discovering new vulnerabilities, and keeping management informed are all important aspects of risk management, they are secondary to the primary need to adapt to the ever-shifting risk environment. Regularly updating assessments ensures that these other elements can be addressed effectively, as they flow from a foundational understanding of the current risks faced.
