What is a method for ensuring data security on a computer?

• A. Using a firewall only
• B. Backing up data regularly
• C. Use of encryption
• D. Only using strong passwords

Answer: (C)

The use of encryption is a highly effective method for ensuring data security on a computer. Encryption serves to transform sensitive data into a code that is unreadable to unauthorized users. This means that even if data is intercepted or accessed by an unauthorized party, they would not be able to decipher or understand the information without the appropriate encryption key or password. This process protects sensitive information such as personal data, financial records, and confidential communications, making it crucial for organizations and individuals alike to implement encryption as part of their overall data protection strategy. By integrating encryption into data security practices, users can safeguard their information against various threats, including hacking, data breaches, and other malicious activities. While other methods, such as using strong passwords and regular data backups, are also important components of a comprehensive data security approach, encryption specifically addresses the confidentiality of data during transmission and storage, providing an additional layer of protection.
