Understanding Data Classification: Importance and Best Practices

The purpose of data classification is to help organizations manage and protect their data more effectively by assigning the appropriate level of security controls to each class of data based on its level of risk. A typical data classification framework may include categories such as public, internal, confidential, and highly confidential. The classification of data is a foundational step in cybersecurity risk management and it helps organizations comply with various regulatory requirements related to data privacy and security.
