Final answer:
RT is an Intrusion prevention system (IPS). It monitors network traffic in real time and blocks potential threats. Therefore, the correct option is c).
Step-by-step explanation:
RT stands for Real-Time. An Intrusion Prevention System (IPS) is a network security device that monitors network traffic in real-time and actively blocks any malicious activity or potential threats that it detects. It works by analyzing network traffic patterns, comparing them to known attack signatures, and blocking any suspicious or unauthorized traffic.
To address the provided options for what RT could stand for in network security, we can provide definitions:
- Inline device – Typically a device that is positioned directly in the path of network traffic. It can act on the network traffic passing through it.
- Intrusion Detection System (IDS) – A system that monitors network traffic for suspicious activity and issues alerts when such activities are detected.
- Intrusion Prevention System (IPS) – Similar to an IDS, but with the capability to prevent or block intrusions that it detects.
- Packet logger – A tool used for capturing packets that transit a network for analysis.
Without the correct context for RT, it is difficult to match it to one of the options provided. More information would be necessary to accurately classify RT as any of these options.
Therefore, the correct option is c).
