Question 70
A scanner marks an internet-facing gateway critical and another equally scored component is not installed anywhere. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.
Explanation
Correct Answers
Review asset versions, affected component evidence, external reachability, exploit preconditions, compensating controls, and vendor advisories. This checks the relevant condition before an engineer modifies production access or detection behavior. A CVE identifies a disclosed issue and CVSS summarizes severity characteristics; neither alone proves exposure or exploitation of a particular asset. The controlled response would be: Triage software vulnerabilities using version applicability, exploit exposure, available remediation, and business impact alongside published CVE and CVSS data. This supplies the diagnostic evidence needed for the complementary action. Situation: A scanner marks an internet-facing gateway critical and another equally scored component is not installed anywhere.
Triage software vulnerabilities using version applicability, exploit exposure, available remediation, and business impact alongside published CVE and CVSS data. This control addresses the failure mechanism and narrows the enforcement boundary. A CVE identifies a disclosed issue and CVSS summarizes severity characteristics; neither alone proves exposure or exploitation of a particular asset. Confirm pre-change conditions using: Review asset versions, affected component evidence, external reachability, exploit preconditions, compensating controls, and vendor advisories. This is the implementation portion of the complementary pair. Situation: A scanner marks an internet-facing gateway critical and another equally scored component is not installed anywhere.

Protected traffic crosses the tunnel with authenticated peers and encrypted data even behind the intended NAT device. This step could matter for IPsec IKE and NAT traversal but is not part of the required complementary pair for this case. The paired steps are: Triage software vulnerabilities using version applicability, exploit exposure, available remediation, and business impact alongside published CVE and CVSS data. and Review asset versions, affected component evidence, external reachability, exploit preconditions, compensating controls, and vendor advisories. Situation: A scanner marks an internet-facing gateway critical and another equally scored component is not installed anywhere.
Apply context-aware output encoding, anti-CSRF protections, and correct cookie controls at the relevant trust boundary. This step could matter for Web injection and request forgery but is not part of the required complementary pair for this case. The paired steps are: Triage software vulnerabilities using version applicability, exploit exposure, available remediation, and business impact alongside published CVE and CVSS data. and Review asset versions, affected component evidence, external reachability, exploit preconditions, compensating controls, and vendor advisories. Situation: A scanner marks an internet-facing gateway critical and another equally scored component is not installed anywhere.
Review message authentication results, sender/domain similarities, original contact directory, transaction changes, and escalation records. This step could matter for Business email compromise verification but is not part of the required complementary pair for this case. The paired steps are: Triage software vulnerabilities using version applicability, exploit exposure, available remediation, and business impact alongside published CVE and CVSS data. and Review asset versions, affected component evidence, external reachability, exploit preconditions, compensating controls, and vendor advisories. Situation: A scanner marks an internet-facing gateway critical and another equally scored component is not installed anywhere.
