Information Technology Specialist (ITS) Cybersecurity 2025 – 400 Free Practice Questions to Pass the Exam

The primary function of encryption is to convert data into a coded format, which is a technique designed to prevent unauthorized access to that data. By transforming the information into a format that is unintelligible to anyone who does not possess the appropriate decryption key or credentials, encryption provides a layer of protection against data breaches and cyber threats. This ensures that sensitive information, such as personal details, financial records, or confidential communications, remains secure and can only be accessed by individuals or systems that are authorized to do so.

While other options might relate to data management or cybersecurity in some aspects, they do not serve the specific purpose of encryption. Compressing data for efficient storage focuses on reducing the physical size of data without the security aspect, increasing internet speed is unrelated to data protection, and blocking unwanted software pertains to malware prevention, not to the confidentiality of data. Therefore, the correct choice aligns directly with the core objective of encryption in safeguarding data integrity and privacy.
