ECIH 212-89 Syllabus Exam Questions Answers

Reducing the success rate of SQL injection attacks is focused on minimizing vulnerabilities within the application's database interactions, rather than the broader server or network services. SQL injection prevention techniques typically involve input validation, parameterized queries, and the use of stored procedures, rather than changes to the network or server configuration.

A) Closing unnecessary application services and ports on the server is a general security best practice to reduce the attack surface but does not directly impact the success rate of SQL injection attacks. This action limits access to potential vulnerabilities across the network and server but doesn't address the specific ways SQL injection exploits input handling within web applications.

B) Automatically locking a user account after a predefined number of invalid login attempts within a predefined interval can help mitigate brute force attacks but has no direct effect on preventing SQL injection, which exploits code vulnerabilities to manipulate database queries.

C) Constraining legitimate characters to exclude special characters and D) Limiting the length of the input field are both direct methods to reduce the risk of SQL injection. They focus on controlling user input, which is the vector through which SQL injection attacks are launched. By restricting special characters that could be used in SQL commands and limiting input lengths, an application can reduce the potential for malicious input to form a part of SQL queries executed by the backend database.

In the context of collecting physical evidence during a cyber forensic investigation, Patrick must consider items like removable media, cables, and publications. These items can contain crucial information related to the crime, such as data storage devices (USB drives, external hard drives), cables connected to potentially relevant devices, and any printed materials that might have information or clues about the incident. Open ports, services, and OS vulnerabilities, DNS information, and published name servers and web application source code, while important in digital forensics, do not constitute physical evidence in the traditional sense.

This scenario focuses on user-driven mitigation of phishing threats, a key element of the ECIH Email Security Incident Handling module. Aarav’s guidance directly reinforces one of the most important user best practices: never engage with suspicious emails.

Option D is correct because avoiding replies or forwarding suspicious emails prevents attackers from validating active accounts, spreading malware, or escalating social engineering attacks. ECIH emphasizes that user interaction often determines the success of phishing campaigns, making awareness and behavior critical controls.

Option A is unrelated to security. Option B is a sender-side control, not a user response. Option C may reduce accidental clicks but does not address the broader behavioral risk.

By instructing users to report, delete, and avoid engagement, Aarav strengthens the organization’s human firewall, which ECIH recognizes as essential in reducing phishing impact.
