Which term refers to the component that stores the complete set of rules to identify a packet and determines the action to be performed?

• A. Suricata
• B. Rule Header
• C. Snort
• D. Wifi Inspector

Answer: (B)

Understanding IDS/IPS rule structure helps here. Each rule in Snort/Suricata has a header and an options section. The header defines the action to take (such as alert, log, or drop) and the basic matching fields (protocol, source IP/port, destination IP/port). This header is the part that contains the identifying criteria and the response to a match, so it’s the component that determines what to do when a packet fits the rule. The engines (Suricata or Snort) run these rules, and the options section adds more specific checks, but the header is where the action and core match criteria live. The other items listed refer to the software or unrelated tools, not to the part of a rule that stores the criteria and action.
