How does web a[plication firewalls prevent attacks?
Correct Answer
C. File injection
Explanation
Web application firewalls prevent attacks by implementing various security measures, including the prevention of file injection. File injection is a type of attack where malicious code is injected into a file, which can then be executed on the server. By detecting and blocking file injection attempts, web application firewalls ensure that malicious code cannot be injected into files and executed, thus preventing potential security breaches and protecting the integrity of the system.

6.
Which of these involves overruling a program or server?
Correct Answer
A. Buffer overflow
Explanation
A buffer overflow occurs when a program or server tries to store more data in a buffer than it can handle, causing the excess data to overwrite adjacent memory locations. This can lead to the execution of malicious code or the crashing of the program/server. Therefore, a buffer overflow involves overruling a program or server by exploiting a vulnerability in its memory management.
7.
Which of these is often done secretly and without regulations?
Correct Answer
A. Debug options
Explanation
Debug options are often done secretly and without regulations. Debug options allow developers to test and troubleshoot their code by providing additional information and tools. However, if not properly regulated, debug options can be exploited by attackers to gain unauthorized access or manipulate the system. Therefore, it is important to have proper regulations and security measures in place when using debug options.
8.
Which of these web application firewall projects is open source?
Correct Answer
A. ModSecurity
Explanation
ModSecurity is an open-source web application firewall project. It is a widely used and highly regarded tool for protecting web applications from various attacks. Being open-source means that the source code of ModSecurity is freely available, allowing developers to modify and customize it according to their needs.

9.
Which of these web application firewalls is not cloud-based?
Correct Answer
C. Radware AppWall
Explanation
Radware AppWall is not a cloud-based web application firewall. This means that it is not hosted on a cloud platform and does not rely on cloud infrastructure for its operation. Instead, it is a traditional on-premises firewall solution that is installed and managed locally on the user's own servers. In contrast, Sucuri Firewall, Alibaba Cloud, and Fastly are all examples of cloud-based web application firewalls that leverage cloud technology to provide their services.
10.
Which of these is not a web application firewall appliance?
Correct Answer
B. Cloudbric
Explanation
Cloudbric is not a web application firewall appliance because it is a cloud-based web security solution rather than a hardware appliance. While the other options mentioned are all physical appliances that provide web application firewall functionality, Cloudbric operates as a cloud-based service that can be accessed and managed remotely. This allows for more flexibility and scalability compared to traditional hardware appliances.
