Which of the following steps might a company take in order to prevent unauthorized individuals from accessing confidential data?

Constructing a firewall to protect its computer system to access its computer system
Requiring a username and password
Both A and B
Neither A nor B

The correct answer is: Constructing a firewall to protect its computer system to access its computer system

The most comprehensive approach to preventing unauthorized access to confidential data involves implementing multiple layers of security. By constructing a firewall, a company establishes a barrier that filters incoming and outgoing network traffic based on predetermined security rules. This is essential as it helps protect the internal network from unauthorized access and threats originating from external sources. While requiring a username and password is a common security measure that adds an essential layer of user verification, it alone may not provide sufficient protection against sophisticated attacks. This is because usernames and passwords can be compromised through various methods, such as phishing or brute-force attacks. Incorporating both a firewall and user authentication mechanisms offers a more robust solution to safeguard confidential data effectively, making the option that includes both measures more suitable for comprehensive data protection strategies.
