CompTIA PT0-003 Dumps Questions Answers

An external assessment focuses on testing the security of internet-facing services. Here’s why option C is correct:

External Assessment: It involves evaluating the security posture of services exposed to the internet, such as web servers, mail servers, and other public-facing infrastructure. The goal is to identify vulnerabilities that could be exploited by attackers from outside the organization’s network.

Segmentation: This type of assessment focuses on ensuring that different parts of a network are appropriately segmented to limit the spread of attacks. It’s more relevant to internal network architecture.

Mobile: This assessment targets mobile applications and devices, not general internet-facing services.

Web: While web assessments focus on web applications, the scope of an external assessment is broader and includes all types of internet-facing services.

Luke HTB: Demonstrates the process of evaluating public-facing services to ensure their security​​.

Conclusion:

Option C, External, is the most appropriate type of assessment for targeting internet-facing services used by the client.

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

The attacker is attempting to access restricted files by navigating directories beyond their intended scope.

Directory Traversal (Option C):

The request uses encoded "../" sequences (%2e%2e%2f = ../) to move up directories and access /etc/passwd.

This is a classic directory traversal attack aimed at accessing system files.

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.
