Which term describes data security against unauthorized access?
-
Encryption
-
Summation
-
Fragmentation
-
Expansion
Correct Answer
A. EncryptionExplanation
Encryption is a security measure that protects data against unauthorized access by converting the information into a code. Encryption ensures that even if data is intercepted, it cannot be read without the correct decryption key. This method is crucial for maintaining the confidentiality of sensitive information, making it a standard practice in data security protocols across various industries, particularly in areas where privacy is paramount, such as finance and healthcare.Rate this question:
