Miguel, a professional hacker, targeted an organization to gain illegitimate access to its critical information. He identified a flaw in the end-point communication that can disclose the target application's data.
Which of the following secure application design principles was not met by the application in the above scenario?

  1. Secure the weakest link
  2. Do not trust user input
  3. Exception handling
  4. Fault tolerance

Answer(s): C

Explanation:

Exception handling is a secure application design principle that states that the application should handle errors and exceptions gracefully and securely, without exposing sensitive information or compromising the system's functionality. Exception handling can help prevent attackers from exploiting errors or exceptions to gain access to data or resources or cause denial-of-service attacks. In the scenario, Miguel identified a flaw in the end-point communication that can disclose the target application's data, which means that the application did not meet the exception handling principle.



A software company is developing a new software product by following the best practices for secure application development. Dawson, a software analyst, is checking the performance of the application on the client's network to determine whether end users are facing any issues in accessing the application.
Which of the following tiers of a secure application development lifecycle involves checking the performance of the application?

  1. Development
  2. Testing
  3. Quality assurance (QA)
  4. Staging

Answer(s): B

Explanation:

The testing tier of a secure application development lifecycle involves checking the performance of the application on the client's network to determine whether end users are facing any issues in accessing the application. Testing is a crucial phase of software development that ensures the quality, functionality, reliability, and security of the application. Testing can be done manually or automatically using various tools and techniques, such as unit testing, integration testing, system testing, regression testing, performance testing, usability testing, security testing, and acceptance testing



Nicolas, a computer science student, decided to create a guest OS on his laptop for different lab operations. He adopted a virtualization approach in which the guest OS will not be aware that it is running in a virtualized environment. The virtual machine manager (VMM) will directly interact with the computer hardware, translate commands to binary instructions, and forward them to the host OS.
Which of the following virtualization approaches has Nicolas adopted in the above scenario?

  1. Hardware-assisted virtualization
  2. Full virtualization
  3. Hybrid virtualization
  4. OS-assisted virtualization

Answer(s): A

Explanation:

Hardware-assisted virtualization is a virtualization approach in which the guest OS will not be aware that it is running in a virtualized environment. The virtual machine manager (VMM) will directly interact with the computer hardware, translate commands to binary instructions, and forward them to the host OS. Hardware-assisted virtualization relies on special hardware features in the CPU and chipset to create and manage virtual machines efficiently and securely34. Full virtualization is a virtualization approach in which the guest OS will not be aware that it is running in a virtualized environment, but the VMM will run in software and emulate all the hardware resources for each virtual machine5. Hybrid virtualization is a virtualization approach that combines hardware-assisted and full virtualization techniques to optimize performance and compatibility6. OS-assisted virtualization is a virtualization approach in which the guest OS will be modified to run in a virtualized environment and cooperate with the VMM to access the hardware resources



Walker, a security team member at an organization, was instructed to check if a deployed cloud service is working as expected. He performed an independent examination of cloud service controls to verify adherence to standards through a review of objective evidence. Further, Walker evaluated the services provided by the CSP regarding security controls, privacy impact, and performance. Identify the role played by Walker in the above scenario.

  1. Cloud auditor
  2. Cloud provider
  3. Cloud carrier
  4. Cloud consumer

Answer(s): A

Explanation:

A cloud auditor is a role played by Walker in the above scenario. A cloud auditor is a third party who examines controls of cloud computing service providers. Cloud auditor performs an audit to verify compliance with the standards and expressed his opinion through a report89. A cloud provider is an entity that provides cloud services, such as infrastructure, platform, or software, to cloud consumers10. A cloud carrier is an entity that provides connectivity and transport of cloud services between cloud providers and cloud consumers10. A cloud consumer is an entity that uses cloud services for its own purposes or on behalf of another entity
