Select ALL defensive uses of Wireshark supported by the lesson.

### Why this is right Wireshark can help investigate malware communications and suspicious activity, troubleshoot network problems, and verify firewall and intrusion detection and prevention operations. It provides packet-level evidence for analysis. ### The concept A packet analyzer shows network traffic in detail, but its output must be interpreted. It can support defensive investigation and verification, yet it cannot prove that a network has no vulnerabilities or guarantee that an attack is impossible. ### The other options - **D. Guaranteeing that a network has no vulnerabilities**: packet analysis is an investigative tool, not a guarantee of security. ### Terms - **IDS/IPS**: Intrusion Detection System/Intrusion Prevention System. These systems detect suspicious activity and, for prevention systems, may also take action against it. ### Remember Wireshark provides evidence about traffic; it does not certify that a network is completely secure.
