A recent zero-day vulnerability is being actively exploited, requires no user interaction or privilege escalation, and has a significant impact to confidentiality and integrity but not to availability. Which of the following CVE metrics would be most accurate for this zero-day threat?
A recent zero-day vulnerability that is actively exploited, requires no user interaction (UI:N) or privilege escalation (PR:N), and significantly impacts confidentiality (C:H) and integrity (I:K) but not availability indicates a high-severity threat. Assessing the key metrics: Attack Vector (AV:N) should be Network, indicating remote exploitability, and Attack Complexity (AC:L) should be Low, given the ease of exploitation. Scope (S:U) remains unchanged, affecting information without propagating. The significant impact on confidentiality and integrity without affecting availability aligns with option A, which accurately captures these criteria.
Which of the following tools would work best to prevent the exposure of PII outside of an organization?
Data Loss Prevention (DLP) tools are specifically designed to identify, monitor, and protect sensitive data, such as Personally Identifiable Information (PII), to prevent unauthorized access or transfer outside of an organization. DLP solutions enforce policies to detect and block the transmission of sensitive data through various channels, thereby ensuring that PII remains secure and confidential within the organization.
An organization conducted a web application vulnerability assessment against the corporate website, and the following output was observed:
Which of the following tuning recommendations should the security analyst share?
The Cross-Domain Misconfiguration refers to issues related to how the web application handles cross-origin requests. To mitigate this risk and control access to resources from different origins, it is best to configure the Access-Control-Allow-Origin header to only allow authorized domains. This helps to prevent unauthorized cross-origin access, reducing the potential for security vulnerabilities associated with cross-domain interactions.
Which of the following items should be included in a vulnerability scan report? (Choose two.)
In a vulnerability scan report, it is essential to include information on the affected hosts and the risk score. The affected hosts section provides details on which systems or devices are vulnerable, allowing for targeted remediation efforts. The risk score evaluates the severity of the vulnerabilities, aiding in prioritization of addressing the most critical issues first. These elements are crucial for understanding both the extent and urgency of the vulnerabilities discovered.
The Chief Executive Officer of an organization recently heard that exploitation of new attacks in the industry was happening approximately 45 days after a patch was released. Which of the following would best protect this organization?
A mean time to remediate of 30 days is the best option to protect the organization. This means that the organization aims to fix vulnerabilities within 30 days of their discovery. Given that the exploitation of new attacks occurs approximately 45 days after a patch is released, having a remediation period shorter than 45 days ensures that vulnerabilities are patched before they can be exploited.
