Which strategy can effectively enhance data security?

• A. Regularly updating software and hardware
• B. Limiting access to network resources
• C. Both A and B
• D. Conducting employee performance reviews

Answer: (C)

Enhancing data security is a multifaceted approach that can be significantly improved through both regularly updating software and hardware, as well as limiting access to network resources. Regular updates are crucial because they patch vulnerabilities that could be exploited by threats such as hackers or malware. Software vendors frequently release updates to address security flaws and improve the resilience of their products. By applying these updates, organizations can protect themselves against known threats and improve their overall security posture.

Limiting access to network resources is equally important as it reduces the chances of unauthorized personnel accessing sensitive data. By implementing strict access controls and ensuring that only authorized users can view or interact with critical information, organizations can minimize the risk of data breaches. This principle of least privilege ensures that individuals have only the access necessary for their job functions, thereby protecting sensitive data from internal and external threats.

By combining both strategies—updating systems to mitigate vulnerabilities and restricting access to sensitive data—a more comprehensive and robust approach to data security is established, making option C the most effective choice for enhancing data security.
