What is the primary reason for classifying information resources according to sensitivity and practicality?

Classifying information resources according to sensitivity and practicality primarily serves to define the appropriate level of access controls. This classification process is critical because it allows organizations to tailor their security measures based on the potential impact that unauthorized access or disclosure could have on the organization and its stakeholders.

For sensitive information, such as personal data or proprietary business information, higher levels of access control are necessary to prevent unauthorized access and mitigate risks associated with data breaches. Conversely, less sensitive information may require fewer controls, allowing for more flexibility in access. The classification helps security professionals understand the value and risk associated with each type of information and implement security measures that are both effective and proportional to the identified risk.

By focusing on the sensitivity of the information, organizations can allocate their resources effectively, ensuring that the most critical information receives the highest level of protection, while also streamlining controls for less sensitive information. This approach aligns security practices with the organization's overall risk management strategy, promoting a more organized and efficient information security program.
