CompTIA CAS-004 CompTIA Advanced Security Practitioner (CASP+) Exam Practice Test

Answer : A

Fuzz testing identifies vulnerabilities by providing unexpected or random input to the application, exposing edge cases and additional attack vectors. This aligns with CASP+ objective 1.5, emphasizing proactive vulnerability discovery techniques in application security.

Answer : D

Answer : B

Framework codeprovides a standardized structure and set of conventions that all team members can follow, ensuring consistency in coding styles across the development team.

Option A (Chain of custody): This relates to tracking and managing code changes for accountability, not standardizing coding styles.

Option C (Two-person integrity): Ensures review and approval for code changes but does not enforce uniform coding styles.

Option D (Code coverage for unit testing): Focuses on test quality rather than addressing inconsistent coding styles.

CompTIA CASP+ Exam Objective 3.3: Apply software development security best practices.

Answer : C

The organization's new email system should provide e-discovery functionality. E-discovery stands for electronic discovery, which is the process of identifying, preserving, collecting, processing, reviewing, analyzing, and producing electronically stored information (ESI) that is relevant to a legal matter. E-discovery can help the organization comply with legal holds, which are orders or notices to preserve relevant ESI when litigation is anticipated or ongoing. E-discovery can also help the organization reduce the costs and risks of litigation, as well as improve the efficiency and accuracy of the discovery process. Verified Reference:

Answer : B

When drafting an agreement between two companies, it is important to clearly define the responsibilities of each party. This is particularly relevant when a software company is looking to integrate with an established product. A shared responsibility agreement ensures that both parties understand their respective responsibilities and are able to work together efficiently and effectively. For example, the software company might be responsible for integrating the product and ensuring it meets user needs, while the established product provider might be responsible for providing ongoing support and maintenance. By outlining these responsibilities in the agreement, both parties can ensure that the platform is built and maintained successfully.

Answer : A

Replacing the current antivirus with an EDR (endpoint detection and response) solution is the best solution for addressing several service outages on the endpoints due to new malware. An EDR solution is a technology that provides advanced capabilities for detecting, analyzing, and responding to threats or incidents on endpoints, such as computers, laptops, mobile devices, or servers. An EDR solution can use behavioral analysis, machine learning, threat intelligence, or other methods to identify new or unknown malware that may evade traditional antivirus solutions. An EDR solution can also provide automated or manual remediation actions, such as isolating, blocking, or removing malware from endpoints. Removing the web proxy and installing a UTM (unified threat management) appliance is not a good solution for addressing service outages on endpoints due to new malware, as it could expose endpoints to more threats or attacks by removing a layer of protection that filters web traffic, as well as not provide sufficient detection or response capabilities for endpoint-specific malware. Implementing a deny list feature on endpoints is not a good solution for addressing service outages on endpoints due to new malware, as it could be ineffective or impractical for blocking new or unknown malware that may not be on the deny list, as well as not provide sufficient detection or response capabilities for endpoint-specific malware. Adding a firewall module on the current antivirus solution is not a good solution for addressing service outages on endpoints due to new malware, as it could introduce compatibility or performance issues for endpoints by adding an additional feature that may not be integrated or optimized with the antivirus solution, as well as not provide sufficient detection or response capabilities for endpoint-specific malware.

Answer : D

Comprehensive and Detailed in-Depth

Understanding the Risk Levels:

Inherent Risk:

Theoriginal riskbefore any controls or mitigation measures are applied.

In this scenario, it represents therisk of automated purchases without CAPTCHA.

Residual Risk:

Theremaining riskaftermitigation strategieshave been applied.

After implementing CAPTCHA, some risk remains asCAPTCHA systems can be bypassedorhuman-operated botsmay still make purchases.

Mitigated Risk:

A risk that has beenreduced or managedeffectively.

While CAPTCHAmitigatesthe issue, it does noteliminateit.

Low Risk:

A risk that is consideredminordue to effective mitigation or low impact.

CAPTCHA reduces risk but does not guarantee it is low.

Transferred Risk:

A risk that has beenshifted to another entity, such asoutsourcing or insurance.

Implementing CAPTCHA does nottransfer riskbut ratherreduces it directly.

Why the Correct Answer is D (Residual):

Implementing CAPTCHAreduces the number of automated purchases, but therisk is not entirely eliminated.

There is always aresidual riskbecause:

Advanced botsmay bypass CAPTCHA systems.

Human-assisted purchasesmight still occur, as attackers might hire people to complete CAPTCHAs.

Therefore, the risk after implementing the CAPTCHA system isresidual, assome potential for automated purchases remains.

Why the Other Options Are Incorrect:

A . Inherent:

Inherent risk existsbeforeany mitigating actions, like CAPTCHA implementation.

Since the CAPTCHA is already suggested, we are addressing theresidual risk.

B . Low:

While CAPTCHA reduces the risk, itdoes not eliminate it completelyor make it negligible.

Attackers can stillbypass CAPTCHAusing more sophisticated methods.

C . Mitigated:

The CAPTCHA reduces risk butdoes not fully mitigate it.

The termmitigatedimplies a more comprehensive reduction than what CAPTCHA alone can provide.

E . Transferred:

There isno transfer of riskto another party or system.

CAPTCHA directlymitigatesrisk rather than shifting responsibility.

Real-World Scenario:

Whenpopular productsare released (like new GPUs), attackers usebotsto make bulk purchases.

Retailers implementCAPTCHA systemsto prevent automated orders.

However,bot developerscontinuously innovate tobypass CAPTCHA, leaving some level ofresidual risk.

Extract from CompTIA SecurityX CAS-005 Study Guide:

TheCompTIA SecurityX CAS-005 Official Study Guidedefinesresidual riskas therisk that remains after controls are implemented. Implementing aCAPTCHAsystem reduces thelikelihoodof automated purchases butdoes not fully eliminate the threat, thus leaving aresidual risk.
