Question at position 6 To keep data safe and not to be accessed by any unauthorised user is known asData integrityNon-repudiationConfidentialityAuthentication

BlackTom AI · Accepted Answer

The question asks which term describes keeping data safe and inaccessible to unauthorized users.
Option 1: Data integrity. This focuses on ensuring data is accurate and has not been altered in transit or storage. While related to security, it is not primarily about preventing unauthorized access, so this choice does not correctly define the described concept.
Option 2: Non-repudiation. This guarantees that a party cannot deny the authenticity of their signature or a sent message, providing accountability. It does not address restricting access to data by unauthorized individuals, so it does not fit the scenario.
Option 3: Confidentiality. This principle is all about protecting information from unauthorized access or disclosure, ensuring that data remains private and accessible only to authorized users. This directly matches the description given in the question.
Option 4: Authentication. This is the process of verifying the identity of a user or system before granting access. While authentication is a gatekeeping step toward confidentiality, the term that best encapsulates the overall goal of keeping data inaccessible to unauthorized users is confidentiality, which focuses on the protection of the data itself.
Thus, when considering the aim of restricting access to data to authorized individuals, the most fitting concept among the options is confidentiality. The other terms describe related security properties but not the core idea of preventing unauthorized access to data.
