Exam CAS-004 topic 1 question 367 discussion

The issue mentioned in the scenario involves known vulnerabilities within the Java runtime environment that cannot be resolved. In addition to the vulnerabilities in the runtime environment, the security engineer should focus on identifying any third-party libraries or dependencies that might also introduce vulnerabilities. Here’s why A is the best option: Software composition analysis (SCA) is a process used to identify known vulnerabilities in third-party libraries and dependencies used by the application. While the core Java runtime may have issues that cannot be immediately resolved, third-party libraries used in the application may also pose security risks. By performing SCA, the security engineer can identify and address vulnerabilities in third-party code, ensuring that those dependencies do not introduce additional risks.

Quick Implementation: Sandboxing can be set up quickly compared to the time and complexity involved in setting up a dedicated VM environment. Minimal Downtime: The application can continue running in the sandbox with minimal interruption, allowing for immediate security testing and mitigation efforts. Flexibility and Focus: Penetration testing within a sandbox provides a focused approach to identifying and addressing vulnerabilities without impacting the main production environment.

D. reduce the attack surface in case the exploits.

D - makes the most sense if we are concerned about downtime

D. Embed the current application into a virtual machine that runs on dedicated hardware. This solution involves using virtualization technology, where the Java application is encapsulated within a virtual machine (VM). This approach allows for isolation and containment of the application, and any issues with the Java runtime environment are confined within the VM. It provides a level of abstraction and separation from the underlying hardware and operating system.

D. Embed the current application into a virtual machine that runs on dedicated hardware. By embedding the Java application into a virtual machine (VM) running on dedicated hardware, you can isolate the application and its environment. This approach allows you to run the Java application while minimizing the impact of known issues in the Java runtime environment. If there are vulnerabilities or issues within the Java runtime, they are less likely to impact the overall system when it's contained within a VM. It provides an additional layer of security and isolation, reducing downtime associated with resolving runtime issues.

Software Composition Analysis Identifies Risks in Open Source Packages. SCA tools identify all open source packages in an application and all the known vulnerabilities of those packages. This knowledge can be used to notify developers of the issues in their code to fix them before they are exploited.

I agree the answer is D

D. Embed the current application into a virtual machine that runs on dedicated hardware - By running the application in a dedicated virtual machine (VM), it's isolated from the rest of the environment. This containment reduces the potential impact of vulnerabilities in the Java runtime since they'd be restricted to the VM. Moreover, embedding an application into a VM typically has a shorter downtime than rewriting the application or extensive testing.
