CompTIA Updated PT0-003 Exam Questions and Answers by dean

Based on the findings, the focus should be on addressing vulnerabilities in libraries and ensuring their security. Here’s why options D and E are correct:

Implement an SCA Tool:

SCA (Software Composition Analysis) tools are designed to analyze and manage open-source components in an application. Implementing an SCA tool would help in identifying and managing vulnerabilities in libraries, aligning with the finding of vulnerable libraries in the secure SDLC process.

This recommendation addresses the high-risk finding related to the Secure SDLC by providing a systematic approach to manage and mitigate vulnerabilities in software dependencies.

Obtain the Latest Library Version:

Keeping libraries up to date is a fundamental practice in maintaining the security of an application. Ensuring that the latest, most secure versions of libraries are used directly addresses the high-risk finding related to vulnerable libraries.

This recommendation is a direct and immediate action to mitigate the identified vulnerabilities.

Other Options Analysis:

Develop a Secure Encryption Algorithm: This is not practical or necessary given that the issue is with the use of a weak algorithm, not the need to develop a new one.

Deploy an Asset Management System: While useful, this is not directly related to the identified high-risk issue of vulnerable libraries.

Write an SDLC Policy: While helpful, the more immediate and effective actions involve implementing tools and processes to manage and update libraries.

References from Pentest:

Horizontall HTB: Demonstrates the importance of managing software dependencies and using tools to identify and mitigate vulnerabilities in libraries​​.

Writeup HTB: Highlights the need for keeping libraries updated to ensure application security and mitigate risks​​.

Conclusion:

Options D and E, implementing an SCA tool and obtaining the latest library version, are the most appropriate recommendations to address the high-risk finding related to vulnerable libraries in the Secure SDLC process.

=================

OS identification in tools like Nmap relies on fingerprinting techniques, which analyze response characteristics (e.g., TCP/IP stack behavior).

The scan cannot gather one or more fingerprints from the target (Option D):

If the system is configured to block ICMP responses, or if certain ports are closed, fingerprinting fails.

Some modern firewalls and intrusion prevention systems (IPS) interfere with OS fingerprinting by modifying packet responses.

A peer review process ensures that a penetration test report is accurate, unbiased, and free from errors.

Peer review (Option B):

Senior security professionals verify findings, risk levels, and remediation recommendations.

Reduces the risk of misinterpretation or incorrect data in reports.

If a wireless network lacks proper encryption, attackers can inject malicious packets into the traffic stream.

Packet injection (Option A):

Attackers forge and transmit fake packets to manipulate network behavior.

Common in WEP/WPA attacks to force IV collisions or spoof DHCP responses.
