Which system focuses on vulnerability discovery and remediation within cyberspace?

• A. Cyberspace Vulnerability Assessment/Hunter (CVA/H)
• B. Cyberspace Defense Analysis (CDA)
• C. Air Force Cyberspace Defense (ACD)
• D. Domain Name System (DNS)

Answer: (A)

Vulnerability discovery and remediation in cyberspace is best handled by Cyberspace Vulnerability Assessment/Hunter. CVA/H is designed to identify security weaknesses, evaluate their risk, and drive remediation across networks and systems, providing automated scanning, detailed results, risk prioritization, and a workflow to close identified gaps. This makes it the right fit for discovering vulnerabilities and guiding fixes. Cyberspace Defense Analysis focuses on assessing defense posture and analyzing adversary operations rather than running vulnerability scans or tracking remediation. Air Force Cyberspace Defense is a broader program that covers defensive operations, not a single tool dedicated to vulnerability discovery and remediation. The Domain Name System, while foundational to Internet infrastructure, is not a tool for vulnerability discovery and remediation.
