The analyst should obtain permission to perform the search before accessing the web-browsing history of an employee, as this may involve privacy or legal issues. The analyst should follow the organization's policies and procedures, and obtain authorization from the appropriate authority, such as the manager, the human resources department, or the legal department.

The correct answer is B. Extract the server's system timeline, verifying hashes and network connections during a certain time frame. A system timeline is a chronological record of the events and activities that occurred on a system, such as file creation, modification, or deletion, process execution, registry changes, or network connections. A system timeline can help an analyst to understand how an attacker compromised a server by showing the sequence of actions and artifacts left by the attacker. An analyst can also verify the hashes of the files and processes involved in the compromise and compare them with known malware signatures or databases. Additionally, an analyst can check the network connections made by the server during the compromise and identify the source and destination IP addresses, ports, and protocols used by the attacker1.

Threat modeling is a process that helps identify and analyze the potential threats and vulnerabilities of a system or process. It can help evaluate the security risks and mitigation strategies of a new business process that would use existing infrastructure to process and store sensitive data. A black-box penetration testing engagement, a tabletop exercise, or a business impact analysis are other methods that can be used to assess the security or resilience of a system or process, but they are not as appropriate as threat modeling for coordinating the right training and testing methodology to respond to new business initiatives or significant changes to existing ones.

Output encoding is a technique that converts user-generated input in a web form before it is displayed by the browser. Output encoding is a form of data sanitization that prevents cross-site scripting (XSS) attacks, which occur when malicious scripts are injected into web pages and executed by unsuspecting users4. Output encoding works by replacing special characters in user input, such as <, >, ", ', &, etc., with their HTML-encoded equivalents, such as <, >, ", ', &, etc. This prevents the browser from interpreting the user input as HTML or JavaScript code and executing it.

Live forensics is a technique that involves investigating an active threat on a system without shutting it down or altering its state, by using tools such as memory dumpers, process explorers, registry editors, or network analyzers. Live forensics can help preserve volatile data that may be lost if the system is powered off or rebooted, such as system memory, network connections, running processes, etc. Live forensics can also help identify and stop malicious activities in real time.
