100-150 Question 126
Single answerA small business network includes IoT devices such as smart thermostats, computers, mobile devices, an IP phone, a networked printer, and a local server. The business reports intermittent connectivity issues and unauthorized access to the printer. Which device should be prioritized for securing the network to minimize such issues?
- A
The smart thermostat
- B
The networked printer
- C
The IP phone
- D
The local server
Show answer and explanation
Correct answer: B
Explanation
In this scenario, the networked printer is the source of the reported unauthorized access and is a common target for attackers, especially if it is misconfigured or using weak credentials. Prioritizing the printer for securing the network will help address both the unauthorized access issue and improve the overall security posture. While other devices also require protection, the printer is the most immediate concern.
- A. Incorrect.
Smart thermostats are IoT devices and could be vulnerable to attacks, but they are not the most likely source of unauthorized access in this scenario. Securing IoT devices is important but may not directly address the printer issue.
- B. Correct.
The networked printer is both the source of reported unauthorized access and often a vulnerable point in networks due to weak default credentials or outdated firmware. Securing the printer directly addresses the issue and improves overall network security.
- C. Incorrect.
IP phones are critical for communication but are not the root cause of the connectivity issues or the unauthorized access described in this scenario. They should still be secured, but they are not the priority here.
- D. Incorrect.
The local server is a critical asset and must be secured, but it is not directly linked to the unauthorized access issue with the printer. It is not the most immediate priority in this context.
