CompTIA Network+ (N10-009)Network SecurityEasy
A company is implementing a new security policy that requires all network devices to be regularly checked for known vulnerabilities and misconfigurations. Which of the following tools would be most effective for automatically identifying these issues across the network?
- AProtocol Analyzer
- BPort Scanner
- CVulnerability Scanner
- DPacket Sniffer
Show answer & explanationAnswer & explanation
Correct answer: C. Vulnerability Scanner
A vulnerability scanner is designed to automatically identify known security weaknesses, misconfigurations, and missing patches on network devices and applications.
Why the other options are wrong
- A. A protocol analyzer examines the details of network protocols and traffic, not system vulnerabilities.
- B. A port scanner identifies open ports on a system, which is a component of vulnerability assessment but not a comprehensive solution for known vulnerabilities and misconfigurations.
- D. A packet sniffer captures and analyzes network traffic, not vulnerabilities.
Vulnerability Scanner
A software tool used to identify security weaknesses in systems, applications, and networks by comparing configurations and software versions against a database of known vulnerabilities.
- Automates the process of identifying security flaws.
- Checks for misconfigurations, missing patches, and weak security settings.
- Provides reports on identified vulnerabilities and often suggests remediation steps.
Memory trick: Tools for security: Scan for weaknesses, Analyze traffic, Guard ports.
