ECCouncil Certified Application Security Engineer (CASE) JAVA 312-96 Exam Dumps: Updated Questions & Answers (October 2025)

To prevent the server name from being displayed in the server response header, you should set the Server attribute to an empty string. This is because the server name is included in the HTTP response headers by default, and setting it to an empty string effectively removes this information, thus not disclosing the identity of the server software being used.

References: The EC-Council’s Certified Application Security Engineer (CASE) JAVA materials cover various aspects of secure application development, including the configuration of servers to enhance security. While the exact configuration details can vary based on the server and environment, the principle of setting the Server attribute to an empty string to hide the server information is a common practice in securing web applications as per the guidelines of secure application development.

The code snippet provided is a Java method designed to validate usernames. It employs a blacklist input validation approach, where it checks if the username contains certain prohibited strings (like “SCRIPT”, “SELECT”, “UNION”, “WHERE”, etc.). If the username contains any of these strings, the method returns false; otherwise, it returns true.

This approach is considered a security mistake because blacklisting is generally not as secure as whitelisting. Blacklisting attempts to identify and block known bad inputs, but attackers can often bypass this by using variations or encodings that are not included in the blacklist. Whitelisting, on the other hand, only allows specifically approved inputs and blocks everything else, making it more secure.

In this specific case:

The developer has created an array of strings containing SQL and script injection keywords.

The validateUserName() function iteratively checks if any of these keywords are present in the username.

If found, it returns false; otherwise true.

A more secure approach would be to use whitelist validation where only specific patterns of usernames are allowed or employ additional layers of security like parameterized queries or prepared statements to prevent SQL injection and encoding/escaping user inputs to prevent XSS attacks.

 In the context of abuse case scenarios, the ‘Threatens Relationship’ is used to describe the interaction between an abuse case and the use case it threatens. This relationship helps to identify potential security threats and the ways in which they can exploit the functionalities of a system. By mapping out these relationships, developers and security engineers can better understand the attack vectors and design appropriate security measures to mitigate them.

STRIDE is a risk assessment model used to identify and rate threats during the threat modeling process. It stands for Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege. Each element of STRIDE represents a specific type of threat that could potentially affect an application, and it is used to systematically assess the security of an application by identifying possible vulnerabilities that could be exploited by these threats.

References: The EC-Council’s Certified Application Security Engineer (CASE) JAVA course emphasizes the importance of threat modeling in the software development lifecycle and specifically mentions the use of models like STRIDE to assess and mitigate risks12.

The @ControllerAdvice annotation is used in Spring Framework to handle exceptions globally across the whole application, not just to an individual controller. It allows you to handle exceptions across multiple @Controllers. This annotation is used alongside @ExceptionHandler to define a global exception handling mechanism.

Here’s how it works:

The @ExceptionHandler annotation is used to define methods in your @ControllerAdvice class that will handle exceptions.

When an exception is thrown, the Spring Framework checks for a matching @ExceptionHandler method in a @ControllerAdvice class.

If a match is found, the exception is handled by the method annotated with @ExceptionHandler.

In Tomcat’s server.xml configuration file, the maxPostSize attribute on a  element is used to specify the maximum size of a POST request that can be accepted by the server. Setting this attribute to a specific byte size will limit the size of uploads based on that size. If set to 0, it indicates that there is no limit on the size of the POST request1.

References: The EC-Council’s Certified Application Security Engineer (CASE) JAVA course includes server configuration and security settings as part of its curriculum, which would cover aspects such as setting upload limits in server configuration files like server.xml for Tomcat1.

To remove the HttpSession object and its values from the client’s system, the developer should use the invalidate() method. This method is called on the HttpSession object itself and marks the session for deletion, removing all its attributes and invalidating the session on the server side. Once a session is invalidated, any new request from the client does not associate with the old session and will typically result in a new session being created if required.

Here’s a step-by-step explanation of how the invalidate() method works:

The developer retrieves the HttpSession object from the HttpServletRequest object using the getSession() method.

The developer calls the invalidate() method on the retrieved HttpSession object.

The server invalidates the session, which means it is no longer recognized and any subsequent requests will not be associated with it.

All objects bound to the session are removed and available for garbage collection.

The client’s next request will not have a valid session, and the server will treat it as a new session if necessary.

In Spring MVC, the @ResponseStatus annotation is used to map custom exceptions to specific HTTP status codes. When an exception is thrown, you can use this annotation to indicate which status code should be returned. For example, if you have a custom exception that represents a resource not found scenario, you can annotate it with @ResponseStatus and specify HttpStatus.NOT_FOUND as the status code. This will result in a 404 status code being returned when the exception is thrown.

References:The use of @ResponseStatus is covered in the EC-Council’s Certified Application Security Engineer (CASE) JAVA training and certification program, which emphasizes the importance of secure application development practices across the Software Development Lifecycle (SDLC). The annotation is also widely documented in Spring MVC resources and tutorials, such as those available on Baeldung and Stack Overflow12.

 To ensure that Tomcat can be shut down only by the user who owns the Tomcat process, the server.xml file should be configured to disable the shutdown port. This is done by setting the port attribute of the  element to -1. The shutdown attribute should be set to a value (like “SHUTDOWN”) that would be known to the server administrator. This configuration prevents remote or unauthorized shutdowns of the Tomcat server via the shutdown port.

References: The information is consistent with best practices for securing Tomcat servers as per the guidelines found in various resources, including Stack Overflow discussions and Tenable® security configurations123. For official EC-Council Application Security Engineer (CASE) JAVA documentation and learning resources, please refer to the EC-Council’s official materials and courses45.

 The state management method that works specifically for a sequence of dynamically generated forms is the use of hidden fields. Hidden fields are a form of web form element that do not appear visible to the user but hold data that can be sent back to the server when the form is submitted. This method is particularly useful for maintaining state across multiple forms because the data in the hidden fields can be carried forward as the user progresses through the sequence of forms. Unlike cookies or sessions, which are maintained by the browser or server and can persist across different sessions and pages, hidden fields are tied to the specific form and its submission, making them suitable for state management in a sequence of dynamically generated forms.
