Which of the following security control types does an acceptable use policy best represent?
Correct Answer: C
When a critical legacy server is segmented into a private network, the security control being used is compensating. Compensating controls are alternative measures put in place to satisfy a security requirement when the primary control is not feasible or practical. In this case, segmenting the legacy server into a private network serves as a compensating control to protect it from potential vulnerabilities that cannot be mitigated directly. Compensating: Provides an alternative method to achieve the desired security outcome when the primary control is not possible. Deterrent: Aims to discourage potential attackers but does not directly address segmentation. Corrective: Used to correct or mitigate the impact of an incident after it has occurred. Preventive: Aims to prevent security incidents but is not specific to the context of segmentation.
Question 142
An analyst is evaluating the implementation of Zero Trust principles within the data plane. Which of the following would be most relevant for the analyst to evaluate?
Correct Answer: C
Zero Trust is a security model that assumes no trust by default, even within the internal network. It relies on continuous verification of the identities and security posture of all users, devices, and applications. Adaptive identity involves dynamically adjusting access based on the continuously assessed risk associated with the user, device, or application. This aligns with the principles of Zero Trust, as it ensures that access permissions are granted based on the current context and risk level.
Question 143
A systems administrator is looking for a low-cost application-hosting solution that is cloud-based. Which of the following meets these requirements?
Correct Answer: A
A serverless framework is a cloud-based application-hosting solution that meets the requirements of low-cost and cloud-based. A serverless framework is a type of cloud computing service that allows developers to run applications without managing or provisioning any servers. The cloud provider handles the server-side infrastructure, such as scaling, load balancing, security, and maintenance, and charges the developer only for the resources consumed by the application. A serverless framework enables developers to focus on the application logic and functionality, and reduces the operational costs and complexity of hosting applications. Some examples of serverless frameworks are AWS Lambda, Azure Functions, and Google Cloud Functions. A type 1 hypervisor, SD-WAN, and SDN are not cloud-based application-hosting solutions that meet the requirements of low-cost and cloud-based. A type 1 hypervisor is a software layer that runs directly on the hardware and creates multiple virtual machines that can run different operating systems and applications. A type 1 hypervisor is not a cloud-based service, but a virtualization technology that can be used to create private or hybrid clouds. A type 1 hypervisor also requires the developer to manage and provision the servers and the virtual machines, which can increase the operational costs and complexity of hosting applications. Some examples of type 1 hypervisors are VMware ESXi, Microsoft Hyper-V, and Citrix XenServer. SD-WAN (Software-Defined Wide Area Network) is a network architecture that uses software to dynamically route traffic across multiple WAN connections, such as broadband, LTE, or MPLS. SD-WAN is not a cloud-based service, but a network optimization technology that can improve the performance, reliability, and security of WAN connections. SD-WAN can be used to connect remote sites or users to cloud-based applications, but it does not host the applications itself. Some examples of SD-WAN vendors are Cisco, VMware, and Fortinet. SDN (Software-Defined Networking) is a network architecture that decouples the control plane from the data plane, and uses a centralized controller to programmatically manage and configure the network devices and traffic flows. SDN is not a cloud-based service, but a network automation technology that can enhance the scalability, flexibility, and efficiency of the network. SDN can be used to create virtual networks or network functions that can support cloud-based applications, but it does not host the applications itself. Some examples of SDN vendors are OpenFlow, OpenDaylight, and OpenStack.

Question 144
An organization recently updated its security policy to include the following statement: Regular expressions are included in source code to remove special characters such as $, |, ;. &, `, and ? from variables set by forms in a web application. Which of the following best explains the security technique the organization adopted by making this addition to the policy?
Correct Answer: C
Explanation Input validation is a security technique that checks the user input for any malicious or unexpected data before processing it by the application. Input validation can prevent various types of attacks, such as injection, cross-site scripting, buffer overflow, and command execution, that exploit the vulnerabilities in the application code. Input validation can be performed on both the client-side and the server-side, using methods such as whitelisting, blacklisting, filtering, sanitizing, escaping, and encoding. By including regular expressions in the source code to remove special characters from the variables set by the forms in the web application, the organization adopted input validation as a security technique. Regular expressions are patterns that match a specific set of characters or strings, and can be used to filter out any unwanted or harmful input. Special characters, such as $, |, ;, &, `, and ?, can be used by attackers to inject commands or scripts into the application, and cause damage or data theft. By removing these characters from the input, the organization can reduce the risk of such attacks. Identify embedded keys, code debugging, and static code analysis are not the security techniques that the organization adopted by making this addition to the policy. Identify embedded keys is a process of finding and removing any hard-coded keys or credentials from the source code, as these can pose a security risk if exposed or compromised. Code debugging is a process of finding and fixing any errors or bugs in the source code, which can affect the functionality or performance of the application. Static code analysis is a process of analyzing the source code without executing it, to identify any vulnerabilities, flaws, or coding standards violations. These techniques are not related to the use of regular expressions to remove special characters from the input.

Question 145
Which of the following penetration testing teams is focused only on trying to compromise an organization using an attacker's tactics?
Correct Answer: B
Red teams are focused only on trying to compromise an organization using an attacker's tactics. They simulate real-world attacks to test the effectiveness of the organization's security defenses and identify vulnerabilities. Red team: Acts as adversaries to simulate attacks and find security weaknesses. White team: Oversees and ensures the rules of engagement are followed during the penetration test. Purple team: Facilitates collaboration between the red team and the blue team to improve security. Blue team: Defends against attacks and responds to security incidents.
