• Rule-based detection methods rely on predefined rules and patterns that are known beforehand. These rules are created based on prior knowledge of what constitutes normal and abnormal behavior.
• Statistical detection, on the other hand, involves analyzing data to identify anomalies. It is based on assumptions about what normal behavior looks like and uses statistical methods to detect deviations from this norm.
• Rule-based systems are typically straightforward but may miss novel attacks that do not match existing rules.
• Statistical methods can detect previously unknown threats by recognizing patterns that deviate from established baselines but may produce more false positives.

Application whitelisting/blacklisting is a technology used to control which applications are allowed to execute on a company’s corporate PCs. Whitelisting allows only approved applications to run, while blacklisting prevents specific applications from running. This approach is effective for managing application usage across an enterprise.

Wireshark is a widely-used network protocol analyzer that allows users to capture and interactively browse the traffic running on a computer network. It provides full packet capture capabilities, enabling detailed analysis of network traffic. References: This is supported by the CBROPS course materials, which discuss security monitoring and the analysis of network traffic, including full packet capture tools like Wireshark
