29. An analyst wants to detect outdated software packages on a server. Which of the following methodologies will achieve this objective?
Answer: D
Credentialed scanning will detect outdated software packages on a server.
Credentialed scanning involves accessing a system with valid credentials to assess the installed software and identify any outdated packages. This method provides a comprehensive view of the software environment, allowing for accurate detection of vulnerabilities.
A) Data loss prevention
Data loss prevention (DLP) focuses on protecting sensitive data from unauthorized access or leaks rather than identifying outdated software. While DLP is crucial for security, it does not provide insights into the current state of software packages on a server.
B) Configuration management
Configuration management involves maintaining and documenting the configuration of systems, but it does not directly assess the current status of software versions. While it may help maintain compliance with standards, it does not specifically target outdated software detection.
C) Common vulnerabilities and exposures
Common vulnerabilities and exposures (CVE) refers to a list of publicly known cybersecurity vulnerabilities. While CVEs help identify known vulnerabilities in software, they do not directly indicate whether a software package is outdated. Therefore, relying solely on CVE information would not effectively detect outdated software.
D) Credentialed scanning
Credentialed scanning is an effective methodology for detecting outdated software packages because it allows the scanning tool to access detailed information about installed software. By using valid credentials, the scan can identify software versions and compare them against the latest updates, thus effectively pinpointing any outdated packages.
Conclusion
Credentialed scanning is the most effective method for detecting outdated software packages, as it provides detailed insights into the software environment. Other options, while relevant to cybersecurity, do not directly address the need to identify obsolete software versions. This distinction makes credentialed scanning the definitive choice for the task at hand.
