Q: To protect Data Privacy, we need

Answer: D) All of these
Explanation: Protecting data privacy is crucial in safeguarding personal and sensitive information from unauthorized access and potential breaches. To achieve comprehensive data protection, several measures are essential:

• Firewalls: These act as a barrier between your computer or network and the internet, monitoring incoming and outgoing traffic to prevent unauthorized access. They help block malicious traffic and protect against cyberattacks.

• Strong Passwords: Using strong, unique passwords for different accounts significantly reduces the risk of unauthorized access. A strong password typically includes a mix of letters (both uppercase and lowercase), numbers, and special characters, making it difficult for hackers to guess or crack.

• Encryption: This process converts data into a code to prevent unauthorized access. Even if encrypted data is intercepted, it cannot be read without the decryption key. Encryption is vital for protecting sensitive information, especially during transmission over the internet.

In addition to these measures, other practices such as regularly updating software, using multi-factor authentication (MFA), and being cautious about sharing personal information online contribute to data privacy. Organizations also implement policies and training programs to ensure that employees understand the importance of data privacy and follow best practices. By combining these strategies, individuals and organizations can create a robust defense against data breaches and maintain the privacy of sensitive information.
