Which core principle relates to maintaining data security and preventing unauthorized access?

The principle that relates to maintaining data security and preventing unauthorized access is centered on integrity and confidentiality. This principle emphasizes the need to protect personal data against unauthorized access and alteration, ensuring that only authorized personnel have access to sensitive information. Integrity refers to the assurance that data is accurate and reliable, while confidentiality pertains to the need to keep data private and secure from unauthorized parties.

By implementing measures that uphold integrity and confidentiality, organizations can enhance their data protection strategies, ensuring compliance with legal standards and bolstering consumer trust. This principle serves as a foundation for various data protection regulations, underpinning the importance of safeguarding individuals' personal information from misuse and breaches, which is a critical component of effective data governance practices.

In contrast, other options like storage limitation focus on how long data can be held, lawfulness pertains to the legality of data collection and processing, and data minimization involves only collecting necessary data. While all these aspects are important for comprehensive data management, they do not specifically address the core issues of maintaining security and preventing unauthorized access, making the integrity and confidentiality principle the most relevant in this context.
