CompTIA Security+ (SY0-701) — Question 82

After an audit, an administrator discovers all users have access to confidential data on a file server. Which of the following should the administrator use to restrict access to the data quickly?

Answer options

• A. Group Policy
• B. Content filtering
• C. Data loss prevention
• D. Access control lists

Correct answer: D

Explanation

Access control lists (ACLs) are the most effective way to define and manage user permissions on a file server, allowing for immediate restrictions. Group Policy, while useful for broader settings, may not provide the rapid specificity needed for this situation. Content filtering and data loss prevention focus on monitoring and preventing data leakage, rather than directly controlling access permissions.
