ISC CISSP Exam With Confidence Using Practice Dumps

The first step of a penetration test plan is to obtain the approval of the company’s management, as well as the consent of the target network’s owner or administrator. This is essential to ensure the legality, ethics, and scope of the test, as well as to define the objectives, expectations, and deliverables of the test. Without proper authorization, a penetration test could be considered as an unauthorized or malicious attack, and could result in legal or reputational consequences . References: : CISSP All-in-One Exam Guide, Eighth Edition, Chapter 7, page 758. : CISSP For Dummies, 7th Edition, Chapter 7, page 234.

A functional drill is a type of disaster recovery and business continuity training that involves a specific test by response teams of individual emergency response functions, such as fire suppression, medical assistance, or data backup. A functional drill is designed to evaluate the performance, coordination, and effectiveness of the response teams and the emergency procedures. A functional drill is not the same as a full-scale simulation, a functional evacuation, or an activation of the backup site. A full-scale simulation is a type of disaster recovery and business continuity training that involves a realistic and comprehensive scenario of an emergency and the subsequent response functions, involving all the stakeholders, resources, and equipment. A functional evacuation is a type of disaster recovery and business continuity training that involves the orderly and safe movement of personnel from a threatened or affected area to a safe location. An activation of the backup site is a type of disaster recovery and business continuity action that involves the switching of operations from the primary site to the secondary site in the event of a disaster or disruption. 

Testing for the security patch level of the environment is the web application control that should be put into place to prevent exploitation of Operating System (OS) bugs. OS bugs are errors or defects in the code or logic of the OS that can cause the OS to malfunction or behave unexpectedly. OS bugs can be exploited by attackers to gain unauthorized access, disrupt business operations, or steal or leak sensitive data. Testing for the security patch level of the environment is the web application control that should be put into place to prevent exploitation of OS bugs, because it can provide several benefits, such as:

• Detecting and resolving any vulnerabilities or issues caused by the OS bugs by applying the latest security patches or updates from the OS developers or vendors
• Enhancing the security and performance of the web applications by using the most secure and efficient version of the OS that supports the web applications
• Increasing the compliance and alignment of the web applications with the security policies and regulations that are applicable to the web applications
• Improving the compatibility and interoperability of the web applications with the other systems or platforms that interact with the web applications

The other options are not the web application controls that should be put into place to prevent exploitation of OS bugs, but rather web application controls that can prevent or mitigate other types of web application attacks or issues. Checking arguments in function calls is a web application control that can prevent or mitigate buffer overflow attacks, which are attacks that exploit the vulnerability of the web application code that does not properly check the size or length of the input data that is passed to a function or a variable, and overwrite the adjacent memory locations with malicious code or data. Including logging functions is a web application control that can prevent or mitigate unauthorized access or modification attacks, which are attacks that exploit the lack of or weak authentication or authorization mechanisms of the web applications, and access or modify the web application data or functionality without proper permission or verification. Digitally signing each application module is a web application control that can prevent or mitigate code injection or tampering attacks, which are attacks that exploit the vulnerability of the web application code that does not properly validate or sanitize the input data that is executed or interpreted by the web application, and inject or modify the web application code with malicious code or data.
