Final answer:
To be secure, data must be unreadable, unusable, and indecipherable to unauthorized individuals, ensuring protection through encryption and other security measures.
Step-by-step explanation:
In order to be secure, data must be unreadable, unusable, and indecipherable to unauthorized individuals. This encompasses a wide range of security measures that are put in place to protect data from unauthorized access and exploitation. When data is unreadable or indecipherable, it means that even if someone were to gain access to it, they would not be able to understand or make sense of it without the appropriate decryption key or method. Additionally, data must be unusable, implying that even if an attacker can read the data, they cannot use it for any meaningful purpose. This is often achieved through encryption, where data is encoded in such a way that only authorized parties can access it in a useful form.
Data security is a critical aspect of protecting sensitive information, and it involves implementing a variety of strategies including encryption, access controls, and other safeguards designed to prevent data breaches and ensure that even if data is accessed by an unauthorized party, it remains protected.
