Generation-based fuzz testing is a strategy where new test data is generated from scratch based on a predefined model that specifies the structure, type, and format of the input data. This approach is systematic and relies on a deep understanding of the format and protocol of the input data to create test cases that are both valid and potentially revealing of vulnerabilities. This contrasts with mutation-based fuzz testing, where existing data samples are modified (mutated) to produce new test cases, and log-based and protocol-based fuzz testing, which use different approaches to test software robustness and security.

Cross-Site Scripting attacks occur when untrusted input is processed and rendered by an application without proper validation or encoding. ECIH web application security guidance identifies input validation and output encoding as the most effective primary defense against XSS.

Option B is correct because sanitizing and validating all user input ensures that malicious scripts are neutralized before being stored or rendered. This addresses the root cause of XSS vulnerabilities.

Option A is a detection control, not a prevention mechanism. Option C improves system security but does not prevent application-level XSS flaws. Option D addresses abuse and DoS scenarios, not script injection.

Therefore, focusing on input validation is the most effective proactive control against XSS, as emphasized in the ECIH curriculum.

IDOR is fundamentally an authorization flaw: the application exposes object identifiers (IDs) and fails to enforce that the requesting user is allowed to access that object. The primary remediation is to implement robust authorization checks—commonly RBAC (C) plus object-level access control—so every request verifies user identity and privileges against the requested resource.

(A) WAFs can help with certain injection patterns, but default WAF rules rarely fix logical authorization flaws like IDOR. A WAF also risks false positives and doesn’t replace secure design. (B) pen testing is important for assurance, but it’s not the primary patch; it helps validate the fix later. (D) encryption protects confidentiality in transit/at rest, but it does not prevent an authenticated user from accessing another user’s records if authorization checks are missing.

Therefore (C) is the correct first-line fix: enforce authorization server-side, avoid predictable identifiers, and ensure access control is consistently applied across all endpoints (including APIs).

The Sarbanes–Oxley Act (SOX) Title V, titled "Analyst Conflicts of Interest," contains measures specifically designed to restore investor confidence in the reporting of securities analysts. It addresses the issue of potential conflicts of interest for securities analysts who recommend stocks and other securities by requiring disclosure of certain relationships and financial interests between analysts and the companies they cover. This part of the SOX Act aims to ensure that investors receive unbiased and accurate information from analysts, thereby helping to restore trust in financial markets. Title V consists of only one section, making it unique compared to other titles within the Act that may encompass multiple sections or provisions.

Risk assumption involves accepting the potential risk and continuing to operate the IT system while implementing controls to reduce the risk to an acceptable level. This strategy acknowledges that some level of risk is inevitable and focuses on managing it through mitigation measures rather than eliminating it entirely. Risk avoidance would entail taking actions to avoid the risk entirely, risk planning involves preparing for potential risks, and risk transference shifts the risk to another party, typically through insurance or outsourcing. Risk assumption is a pragmatic approach that balances the need for operational continuity with the imperative of risk management.

Alert Logic is a cloud-based security tool that provides Security-as-a-Service solutions including threat management, vulnerability assessment, and improved security outcomes. It is designed specifically to secure cloud resources and services, making it an ideal choice for organizations like Sam Morison Inc. that are moving their operations to the cloud and are concerned about the security of their data. Tools like Nmap, Burp Suite, and Wireshark, while valuable in certain contexts, do not offer the same cloud-focused security capabilities as Alert Logic.

According to the ECIH Risk Assessment and Recovery module, neutralizing the vulnerability is the top priority during active exploitation, even in nation-state scenarios.

Option C is correct because immediately patching and deploying updates removes the attacker’s access vector and prevents further compromise. ECIH discourages counter-hacking and premature disclosure without containment.

Options A and B may follow after stabilization. Option D is illegal and prohibited.

Therefore, rapid patching is the correct primary action.

When malware moves from the delivery stage to the exploitation stage in the cyber kill chain, its objective often shifts to identifying exploitable vulnerabilities within the targeted system. A port scan is a technique used to discover services that are listening on ports within a system. By scanning the system's ports, the malware can identify open ports and the services running on them, providing valuable information about potential entry points for further exploitation. This type of reconnaissance attack is aimed at gathering intelligence on the target system's network services, which can then be reported back to a command and control center for further malicious activity planning.

Port scanning is more relevant than IP range sweeps, packet sniffing, or session hijacking for identifying useful services on a system because it directly targets the discovery of accessible network services and their corresponding ports. While the other methods can also be part of the reconnaissance phase, they serve different purposes: IP range sweeps aim to identify active IP addresses, packet sniffing intercepts data packets to gather information, and session hijacking involves taking over a valid user session. In contrast, port scanning is specifically designed to enumerate services that could be exploited.

The EC-Council Incident Handler (ECIH) curriculum explains that insider data exfiltration frequently occurs through legitimate channels such as HTTPS to bypass traditional firewall rules. When encrypted traffic is not inspected, sensitive data can be transmitted without detection.

Data Loss Prevention (DLP) tools monitor, detect, and block unauthorized transmission of sensitive information across endpoints, networks, and cloud services. DLP solutions can inspect encrypted traffic (when integrated with SSL/TLS inspection mechanisms) and enforce policies that prevent confidential data from leaving the organization.

The absence of deep packet inspection allowed encrypted HTTPS traffic to evade detection. Implementing DLP would provide content-aware monitoring and policy-based enforcement, reducing insider exfiltration risk.

Option A (biometric authentication) controls access, not outbound data flows. Option C (secure coding) relates to software development security. Option D (USB blocking) addresses removable media exfiltration, not encrypted network traffic.

Therefore, implementing Data Loss Prevention (DLP) tools is the appropriate eradication control.

ECIH forensic readiness guidance identifies the Windows Registry as a primary source for USB device artifacts. The Enum\USB registry key stores vendor IDs, product IDs, serial numbers, and connection history.

Option A is correct because it provides direct evidence of which USB devices were connected, when they were installed, and on which system—critical for insider investigations.

Option B cannot reliably identify physical USB usage. Option C contains driver installation data but is less comprehensive. Option D is irrelevant.

Registry analysis is a foundational forensic technique in ECIH, making Option A correct.
