28. Which of the following can be best used to discover a company's publicly available breach information?
Answer: A
OSINT is the best method to discover a company's publicly available breach information.
Open Source Intelligence (OSINT) refers to the collection and analysis of publicly available data, which makes it an effective tool for discovering a company's breach information that is accessible to the public.
A) OSINT
OSINT is specifically designed to gather information from publicly available sources such as websites, social media, and news articles. This makes it the most suitable choice for discovering breach information, as many breaches are reported in public forums and databases that OSINT tools can effectively analyze.
B) SIEM
Security Information and Event Management (SIEM) systems are primarily used for real-time monitoring and management of security incidents within an organization. While they are valuable for internal threat detection, they do not focus on public data, making them less relevant for discovering publicly available breach information.
C) CVE
Common Vulnerabilities and Exposures (CVE) is a database that provides identifiers for known vulnerabilities. While it can inform about vulnerabilities that could lead to breaches, it does not directly provide information about specific breaches that have occurred within a company, thus limiting its applicability in this context.
D) CVSS
Common Vulnerability Scoring System (CVSS) is a framework for rating the severity of security vulnerabilities. Although it aids in assessing the impact of vulnerabilities, it does not offer insights into publicly available breach information, as it focuses on scoring rather than information disclosure.
Conclusion
OSINT is the most effective method for uncovering a company's publicly available breach information due to its focus on collecting and analyzing data from open sources. In contrast, SIEM, CVE, and CVSS serve different purposes that do not directly facilitate the discovery of breach information, thereby confirming OSINT as the superior choice in this context.
