• 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.

User interaction is any event that requires the user to perform an action that enables or facilitates a cyberattack. Opening a malicious file is an example of user interaction, as it can trigger the execution of malicious code or malware that can compromise the system or network. Gaining root access, executing remote code, and reading and writing file permissions are not user interactions, but rather actions that can be performed by an attacker after exploiting a vulnerability or bypassing security controls. References: Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, More than 99% of cyberattacks rely on human interaction

Reflective XSS, also known as Non-Persistent XSS, occurs when an attacker sends a malicious script to a user through a web application, and the script is executed immediately in the user’s browser without being stored on the server. This type of attack is typically carried out by including the malicious script in a URL, which is then sent to the victim. When the victim clicks on the link, the script runs in their browser, reflecting the attacker’s actions without storing the payload for repeated use12. References: OWASP Foundation’s documentation on Cross-Site Scripting (XSS) provides detailed information on the different types of XSS attacks, including Reflective XSS
