What should the information security manager do when the IT function claims a business impact analysis update is unnecessary for a new application?

An information security manager plays a critical role in ensuring that security policies align with business objectives and that risks are appropriately managed. When the IT function claims that a business impact analysis (BIA) update is unnecessary for a new application, verifying the decision with the business units is essential.

The rationale for this is rooted in the understanding that a BIA evaluates the potential effects of an interruption to critical business operations. Business units have unique knowledge regarding their operational priorities, processes, and recovery requirements. By consulting them, the information security manager can ascertain if there are specific risks or impacts associated with the new application that have not been considered by the IT function. Engaging with business units ensures that any potential disruptions or risks are adequately identified and addressed, thereby minimizing future security vulnerabilities.

Furthermore, aligning risk management activities with business needs is a fundamental aspect of effective information risk management. This collaboration fosters a culture of security awareness and encourages informed decision-making across the organization.
