What is classified as a Major Application?

A Major Application is defined as a set of IT resources that, if compromised, could significantly harm the confidentiality, integrity, and availability of information and systems. This classification emphasizes the importance of these applications to the organization’s mission and potential risks associated with their failure or compromise.

Major Applications usually have a significant impact on the business operations or processes, making their protection a top priority in the risk management and security frameworks. This aligns with standards such as FISMA and NIST, which focus on identifying and prioritizing important applications in terms of security vulnerability. By ensuring that Major Applications are secured, organizations can mitigate risks that could lead to severe consequences, including financial loss, legal issues, and damage to reputation.

The other choices do not encompass the criteria necessary to define a Major Application. Small programs or internal tools may serve specific functions but do not necessarily carry the same level of risk or impact on the overall operations of the organization. A collection of mobile applications can vary greatly in importance and security needs, but not all of them would qualify as Major Applications based on the defined criteria.
