Question 3
A cyber operations team informs a security analyst about a new tactic malicious actors are using to compromise networks.
SIEM alerts have not yet been configured. Which of the following best describes what the security analyst should do to identify this behavior?
  1. Digital forensics
  2. E-discovery
  3. Incident response
  4. Threat hunting
Correct answer: D
Explanation:
Threat hunting is the process of proactively searching for signs of malicious activity or compromise in a network, rather than waiting for alerts or indicators of compromise (IOCs) to appear. Threat hunting can help identify new tactics, techniques, and procedures (TTPs) used by malicious actors, as well as uncover hidden or stealthy threats that may have evaded detection by security tools. Threat hunting requires a combination of skills, tools, and methodologies, such as hypothesis generation, data collection and analysis, threat intelligence, and incident response.Threat hunting can also help improve the security posture of an organization by providing feedback and recommendations for security improvements.

Question 4
A security administrator would like to protect data on employees' laptops. Which of the following encryption techniques should the security administrator use?
  1. Partition
  2. Asymmetric
  3. Full disk
  4. Database
Correct answer: C
Explanation:
Full disk encryption (FDE) encrypts all the data on a disk drive, protecting the data at rest on the entire laptop, including the operating system, applications, and user files. This ensures that if a laptop is lost or stolen, the data cannot be accessed without the correct decryption key.

Question 5
Which of the following security control types does an acceptable use policy best represent?
  1. Detective
  2. Compensating
  3. Corrective
  4. Preventive
Correct answer: D
Explanation:
Preventive - an acceptable use policy enforces rules to users to use company resources.example - company A states that in order to access files in the company server you must connect to your company VPN when working from home. This prevents you from connecting from an insecure network.

Question 6
An IT manager informs the entire help desk staff that only the IT manager and the help desk lead will have access to the administrator console of the help desk software. Which of the following security techniques is the IT manager setting up?
  1. Hardening
  2. Employee monitoring
  3. Configuration enforcement
  4. Least privilege
Correct answer: D
Explanation:
The principle of least privilege is a security concept that limits access to resources to the minimum level needed for a user, a program, or a device to perform a legitimate function. It is a cybersecurity best practice that protects high-value data and assets from compromise or insider threat. Least privilege can be applied to different abstraction layers of a computing environment, such as processes, systems, or connected devices. However, it is rarely implemented in practice.In this scenario, the IT manager is setting up the principle of least privilege by restricting access to the administrator console of the help desk software to only two authorized users: the IT manager and the help desk lead. This way, the IT manager can prevent unauthorized or accidental changes to the software configuration, data, or functionality by other help desk staff.The other help desk staff will only have access to the normal user interface of the software, which is sufficient for them to perform their job functions.The other options are not correct. Hardening is the process of securing a system by reducing its surface of vulnerability, such as by removing unnecessary software, changing default passwords, or disabling unnecessary services. Employee monitoring is the surveillance of workers' activity,such as by tracking web browsing, application use, keystrokes, or screenshots. Configuration enforcement is the process of ensuring that a system adheres to a predefined set of security settings, such as by applying a patch, a policy, or a template.

Question 7
Which of the following roles, according to the shared responsibility model, is responsible for securing the company's database in an IaaS model for a cloud environment?
  1. Client
  2. Third-party vendor
  3. Cloud provider
  4. DBA
Correct answer: A
Explanation:
According to the shared responsibility model, the client and the cloud provider have different roles and responsibilities for securing the cloud environment, depending on the service model. In an IaaS (Infrastructure as a Service) model, the cloud provider is responsible for securing the physical infrastructure, such as the servers, storage, and network devices, while the client is responsible for securing the operating systems, applications, and data that run on the cloud infrastructure. Therefore, the client is responsible for securing the company's database in an IaaS model for a cloud environment, as the database is an application that stores data. The client can use various security controls, such as encryption, access control, backup, and auditing, to protect the database from unauthorized access, modification, or loss. The third-party vendor and the DBA (Database Administrator) are not roles defined by the shared responsibility model, but they may be involved in the implementation or management of the database security.

Question 8
A security team is reviewing the findings in a report that was delivered after a third party performed a penetration test. One of the findings indicated that a web application form field is vulnerable to cross-site scripting. 
Which of the following application security techniques should the security analyst recommend the developer implement to prevent this vulnerability?
  1. Secure cookies
  2. Version control
  3. Input validation
  4. Code signing
Correct answer: C
Explanation:
Input validation is a technique that checks the user input for any malicious or unexpected data before processing it by the web application. Input validation can prevent cross-site scripting (XSS) attacks, which exploit the vulnerability of a web application to execute malicious scripts in the browser of a victim. XSS attacks can compromise the confidentiality, integrity, and availability of the web application and its users. Input validation can be implemented on both the client-side and the server-side, but server-side validation is more reliable and secure. Input validation can use various methods, such as whitelisting, blacklisting, filtering, escaping, encoding, and sanitizing the input data.

Question 9
Which of the following must be considered when designing a high-availability network? (Choose two).
  1. Ease of recovery
  2. Ability to patch
  3. Physical isolation
  4. Responsiveness
  5. Attack surface
  6. Extensible authentication
Correct answer: AD
Explanation:
Ease of recovery: High-availability networks should be designed in a way that allows for quick and easy recovery in the event of a failure. Redundancy, failover mechanisms, and backup systems are some of the components that can help facilitate smooth recovery.Responsiveness: High-availability networks need to be responsive to ensure that any potential issues or failures are quickly detected, and appropriate actions are taken promptly to minimize downtime and impact.

Question 10
A technician needs to apply a high-priority patch to a production system. Which of the following steps should be taken first?
  1. Air gap the system.
  2. Move the system to a different network segment.
  3. Create a change control request.
  4. Apply the patch to the system.
Correct answer: C
Explanation:
A change control request is a document that describes the proposed change to a system, the reason for the change, the expected impact, the approval process, the testing plan, the implementation plan, the rollback plan, and the communication plan. A change control request is a best practice for applying any patch to a production system, especially a high-priority one, as it ensures that the change is authorized, documented, tested, and communicated. A change control request also minimizes the risk of unintended consequences, such as system downtime, data loss, or security breaches.
