CompTIA Security+ (SY0-701) — Question 509

A systems administrator just purchased multiple network devices. Which of the following should the systems administrator perform to prevent attackers from accessing the devices by using publicly available information?

Answer options

• A. Install endpoint protection.
• B. Disable ports/protocols.
• C. Change default passwords.
• D. Remove unnecessary software.

Correct answer: C

Explanation

Changing default passwords is crucial because many attackers exploit default credentials to gain unauthorized access. The other options, while beneficial for security, do not directly address the risk posed by default passwords, which are widely known and can be easily exploited.
