Network Defense Essentials (NDE) 2026 – 400 Free Practice Questions to Pass the Exam

Implementing Intrusion Prevention Systems (IPS) and Intrusion Detection Systems (IDS) is a critical practice for network defenders aiming to protect smart devices from IoT threats. These systems play a fundamental role in identifying and mitigating malicious traffic and suspicious activities within the network environment.

An IPS actively monitors network traffic and can block potential threats in real-time, taking immediate action to prevent unauthorized access or attacks. Moreover, an IDS serves the purpose of alerting administrators to possible security breaches or anomalies, enabling them to respond swiftly to potential threats. By utilizing both systems, network defenders can enhance the overall security posture of their network, particularly concerning vulnerable IoT devices that may be entry points for cybercriminals.

The other choices do not contribute effectively to securing IoT devices. Enabling all open ports increases the risk of unauthorized access, while allowing guest access for troubleshooting can expose the network to additional vulnerabilities. Disabling encryption compromises the integrity and confidentiality of data transmitted between devices, making the network more susceptible to interception and attacks. Thus, focusing on robust monitoring and protection mechanisms, such as IPS and IDS, is essential in defending against the evolving landscape of IoT threats.
