What is a significant outcome of effective encryption?

• A. It allows unrestricted access to data.
• B. It protects data from unauthorized access.
• C. It eliminates the need for firewalls.
• D. It organizes data for better access management.

Answer: (B)

Effective encryption serves as a crucial cybersecurity measure that safeguards sensitive information by transforming it into a format that is unreadable to anyone who does not possess the correct decryption key. This process is fundamental in protecting data from unauthorized access. When data is encrypted, even if it is intercepted or accessed by malicious actors, they cannot comprehend or utilize the information without the decryption mechanisms in place. This ensures confidentiality and integrity, making it an essential practice for securing personal, financial, and proprietary information across various platforms. In contrast, the other options do not accurately represent the function of encryption. For instance, unrestricted access to data contradicts the primary purpose of encryption, which is to limit access based on permissions. Similarly, while firewalls are important for network security, they are separate from encryption and do not eliminate the need for it; both encryption and firewalls serve distinct but complementary roles in a comprehensive security strategy. Lastly, organizing data for better access management relates more to data governance and management practices rather than encryption itself, which focuses strictly on protecting the data's confidentiality.
