Exam SY0-701 topic 1 question 520 discussion

The correct answer is: D. Zero-day Explanation: Zero-day vulnerabilities are the most difficult to remediate because they are unknown to the software vendor or the open-source community at the time of exploitation. Since the company relies on open-source libraries, it may not have control over the discovery or patching of such vulnerabilities. Remediation often depends on the open-source community or third-party maintainers to identify and fix the issue, which can take time. Buffer overflow (A), SQL injection (B), and Cross-site scripting (C) are well-known vulnerability types with established remediation practices. These can typically be addressed through code reviews, secure coding practices, and applying patches or updates provided by the open-source community. Thus, zero-day vulnerabilities pose the greatest challenge due to their unpredictable nature and reliance on external parties for fixes.

The correct answer is D. Zero-day. A zero-day vulnerability refers to a security flaw that is unknown to the software's creators or the public and has no available patch. Since the company relies on open-source software libraries, a zero-day in one of those libraries would be especially difficult to remediate because the company may need to wait for the open-source community or maintainers to discover and fix the vulnerability.
