Restoring web application services with the help of existing backups, as performed by Robert, falls under the Recovery stage of the Incident Handling and Response (IH&R) process. The Recovery stage involves actions taken to return the organization to normal operations after an incident, which includes restoring systems to their operational state using backups, patching vulnerabilities, and ensuring that all systems are clean and secure before being brought back online. This step is crucial for resuming business operations and mitigating the impact of the incident.

Wireshark is a widely used network protocol analyzer that helps in capturing and interactively browsing the traffic on a network. It is an essential tool for incident responders like Eric who are developing incident-handling plans and procedures. By analyzing network traffic, Wireshark allows users to see what is happening on their network at a microscopic level, making it invaluable for troubleshooting network problems, analyzing security incidents, and understanding network behavior. Whois is used for querying databases that store registered users or assignees of an Internet resource. Burp Suite is a tool for testing web application security, and FaceNiff is used for session hijacking within a WiFi network, which makes Wireshark the best choice for analyzing network traffic.

The GPG18 and Forensic readiness planning (SPF) principles outline various guidelines to enhance an organization's readiness for forensic investigation and response. Principle 5, which suggests that organizations should adopt a scenario-based Forensic Readiness Planning approach that learns from experience gained within the business, emphasizes the importance of being prepared for a wide range of potential incidents by leveraging lessons learned from past experiences. This approach helps in continuously improving forensic readiness and response capabilities by adapting to the evolving threat landscape and organizational changes.

ECIH emphasizes that advanced persistent threats require intelligence beyond static indicators. While IOCs are useful, they often change quickly and provide limited context.

Option B is correct because collaboration with industry peers enables sharing of tactics, techniques, and procedures (TTPs), which are more stable and actionable than IOCs. ECIH strongly promotes information sharing communities, ISACs, and trusted peer collaboration to improve situational awareness against APTs.

Options A, C, and D provide partial or outdated insights and lack operational depth.

Therefore, peer collaboration focused on attacker behavior is the most effective approach.
