What measure could a company take to prevent unauthorized access to confidential data?

1. Requiring a username and password

2. Constructing a firewall for its computer system

3. Both A and B

4. Neither A nor B

The correct answer is: Both A and B

To prevent unauthorized access to confidential data, implementing both a username and password system and constructing a firewall are effective measures. Requiring a username and password is a fundamental security protocol that helps ensure that only individuals with the correct credentials can access sensitive information. This method establishes a basic level of authentication, ensuring that users are who they claim to be. It is a common safeguard against unauthorized access. Additionally, constructing a firewall acts as a barrier between the company's internal network and external threats, such as hackers or malicious software. A firewall monitors and controls incoming and outgoing network traffic based on predetermined security rules, further securing the company's data from unauthorized access attempts. By combining both measures, a company significantly enhances its data security strategy. The username and password system provides a basic layer of user authentication, while the firewall offers a broader protective measure against network-based threats. Together, they create a more robust defense against unauthorized access to confidential data.
