Ace Your 312-96 Application Security Exam

 The account lockout mechanism is designed to prevent brute-force attacks by locking an account after a certain number of failed login attempts. However, this security feature can be abused to perform a Denial-of-Service (DoS) attack. An attacker could deliberately fail the login process multiple times for a legitimate user’s account, causing the account to be locked and preventing the legitimate user from accessing their account. This type of attack exploits the security feature to deny service to legitimate users.

References: The explanation aligns with the security testing guidelines provided by the OWASP Foundation, which discusses the balance required in account lockout mechanisms to protect against unauthorized access while not denying access to authorized users1. Additionally, research papers such as those from Worcester Polytechnic Institute detail how account lockout mechanisms can be exploited to create DoS attacks2.

To enable the Struts validator, you typically need to set the validate attribute to “true” in the Struts configuration file. This is done within the  section of the struts-config.xml file, where you define your form beans and their associated validation rules. Here’s a step-by-step explanation:

• Open the struts-config.xml file.
• Locate the  section.
• For each form bean that requires validation, ensure that the validate attribute is set to “true”.
• Define your validation rules in a separate XML file, typically named Validation.xml.
• Link this validation file with your form bean using the  tags.
• Ensure that the  plug-in is defined in your struts-config.xml file to enable the validation framework.

References: While I can’t provide direct references to the EC-Council’s CASE JAVA courses and study guides, you can refer to the official Struts documentation and community resources for more information on configuring the validator in Struts applications. The official Apache Struts website would be a good starting point.

The phase in threat modeling where applications are decomposed and their entry points are reviewed from an attacker’s perspective is known as Attack Surface Evaluation. This phase involves identifying all the points where an unauthorized user could potentially enter or extract data from the system. It is a critical step in securing applications as it helps to understand all the potential vulnerabilities that could be exploited.

During Attack Surface Evaluation, the application is broken down into its constituent components, and each is analyzed for potential weaknesses. This includes reviewing all forms of input and output, authentication mechanisms, access controls, and the overall architecture of the application. By understanding the attack surface, security teams can better anticipate how an attacker might attempt to breach the system and take steps to mitigate those risks.

References:For more detailed information, please refer to the EC-Council’s Certified Application Security Engineer (CASE) JAVA courses and study guides, which provide extensive coverage on threat modeling, including Attack Surface Evaluation12. These resources will offer a comprehensive understanding of the process and its importance in the context of application security.

The image depicts a scenario characteristic of a Cross-Site Scripting (XSS) attack. In this type of attack, an attacker exploits a vulnerability in a web application to send malicious scripts to an unsuspecting user’s browser. The script is then executed by the browser as if it came from a trusted source, which can lead to unauthorized actions being performed on behalf of the user, such as stealing cookies or session tokens.

The steps typically involved in an XSS attack are:

• The user logs into a trusted server using their credentials.
• The server sets a session cookie in the user’s browser.
• The attacker sends a phishing email, tricking the user into sending a request to a malicious site.
• The user requests a page from the malicious server.
• The response page from the malicious server contains the malicious script.
• The malicious script is executed in the context of the trusted server when the user views the response page.

References: While I can provide a general explanation based on my training data, I do not have access to specific EC-Council Application Security Engineer (CASE) JAVA documents and learning resources to provide direct references. However, the EC-Council offers various courses and study guides on application security that cover XSS and other security threats in detail. These resources would typically include the Certified Application Security Engineer (CASE) Java course, which provides comprehensive coverage of security challenges and best practices for Java applications.
