66. After a security incident, a systems administrator asks the company to buy a NAC platform. Which of the following attack surfaces is the systems administrator trying to protect?
Answer: B
The systems administrator is trying to protect the Wired attack surface.
The focus of the systems administrator's request for a NAC (Network Access Control) platform is primarily on securing the Wired attack surface. This is crucial as wired networks are often the backbone of enterprise infrastructure and can be vulnerable to various security threats.
A) Bluetooth
Bluetooth is a wireless technology that enables short-range communication between devices. While it is a potential attack surface, the implementation of a NAC platform typically focuses on wired connections, making this option less relevant in the context of the systems administrator's request.
B) Wired
The Wired attack surface encompasses physical connections to the network, which are often targeted by attackers seeking unauthorized access. A NAC platform is specifically designed to enforce security policies on these connections, ensuring that only authorized devices can access the network, thereby directly addressing the systems administrator's concerns.
C) NFC
NFC (Near Field Communication) is another form of short-range communication, similar to Bluetooth. However, it is not commonly associated with the broader network security concerns that a NAC platform addresses, especially in enterprise environments where wired connections are more prevalent.
D) SCADA
SCADA (Supervisory Control and Data Acquisition) systems are used in industrial environments to monitor and control processes. While securing SCADA systems is important, a NAC platform's primary function is not focused on SCADA but rather on managing access to network resources, particularly in wired networks.
Conclusion
In summary, the systems administrator's request for a NAC platform is specifically aimed at securing the Wired attack surface, which is critical for maintaining the integrity of the company's network. Other options, such as Bluetooth, NFC, and SCADA, do not align with the primary purpose of NAC solutions, which is to manage and secure wired connections effectively.
