The correct answer is D because the root cause of the breach was an unpatched, outdated Apache HTTP Server vulnerable to remote code execution. According to CEH principles under Security Operations and Incident Response, vulnerability management and risk assessment are critical components of defensive security strategy. An extensive risk assessment enables the organization to identify vulnerable assets, prioritize patching based on severity and business impact, and implement a structured remediation plan.

Risk assessment is part of the vulnerability management lifecycle, which includes asset identification, vulnerability scanning, risk evaluation, prioritization, patch management, and verification. By determining which systems are most exposed and critical, the organization can apply patches and security updates systematically, reducing the attack surface. Since the breach occurred due to a known vulnerability, proper patch management and regular security updates would have prevented exploitation.

Options A, B, and C represent hardening or segmentation techniques but do not directly address the core issue of outdated software vulnerabilities. Blocking ports and using dedicated machines are good security practices; however, they do not eliminate the risk of exploitation if the web server software itself remains unpatched. Therefore, implementing a comprehensive risk assessment process followed by prioritized patch management aligns directly with CEH-recommended best practices for preventing similar future incidents.

The correct answer is C because the activity described is specifically known as dumpster diving. In CEH social engineering and reconnaissance concepts, dumpster diving refers to searching through an organization’s discarded materials to obtain sensitive or useful information. Attackers may look for printed documents, network diagrams, employee lists, invoices, sticky notes, password reminders, hardware labels, old storage media, or other items that reveal details about the target environment. Although this activity can support intelligence gathering and reconnaissance, those terms are broader phases or objectives. Social engineering is also a broader category that includes manipulating people or exploiting human behavior, and dumpster diving is commonly treated as one technique within that area. The question asks what best describes the exact activity of going through a company’s garbage, so the most precise option is dumpster diving. Organizations reduce this risk by enforcing secure disposal practices such as shredding documents, sanitizing media, locking trash areas, and training employees on information handling.

The correct answer is C. Regenerate the session ID after a successful login.

The scenario describes session fixation. In a session fixation attack, the attacker causes the victim to use a known session identifier before authentication. After the victim successfully logs in, the application continues using the same session ID, allowing the attacker to reuse that fixed value.

CEH-aligned session hijacking material explains that session fixation allows an attacker to provide a valid session ID and force the victim’s browser to use it. After the victim logs in, the web server continues the same session, and the attacker can use the known session ID to access the legitimate user account . CEH web application material also states that if an application uses the same session ID before and after login, it can result in session fixation; therefore, the application must generate a new session ID before and after login and invalidate the old one on termination .

Option A is incorrect because cache directives reduce caching of sensitive responses but do not prevent fixed session IDs.

Option B is incorrect because SSL/TLS protects traffic in transit, but it does not stop an attacker from pre-setting a session identifier.

Option D can reduce exposure, but the direct and standard countermeasure is regenerating the session ID after successful authentication.

Therefore, the best answer is C. Regenerate the session ID after a successful login.

This scenario describes a worm infection, as defined in CEH v13 Malware Threats. Worms are self-replicating malware that spread autonomously across networks without user interaction. Their propagation often results in excessive network traffic, system crashes, and resource exhaustion, which aligns with the symptoms described.

CEH v13 differentiates worms from other malware:

Ransomware encrypts data but does not self-propagate aggressively.

Trojans require user execution.

Rootkits focus on stealth and persistence rather than replication.

The appropriate response prioritizes containment and eradication. Quarantining affected systems prevents further spread. A network-wide antivirus sweep with updated signatures removes known worm variants. Updating operating systems closes vulnerabilities that worms exploit for propagation.

CEH v13 stresses rapid isolation and patching as critical measures to control worm outbreaks and restore network stability. Therefore, Option A is correct.
