A. B. C. D.C.
The most appropriate source for a security analyst to obtain relevant and timely threat information concerning the financial services industry is Information sharing and analysis membership (option C).
Option A (real-time and automated firewall rules subscriptions) refers to a technical solution that helps protect a network by blocking traffic that does not meet certain predefined criteria. Although it may provide some level of protection, it does not necessarily provide threat intelligence specific to the financial services industry.
Option B (open-source intelligence, such as social media and blogs) refers to publicly available information that can be gathered from the internet, including social media and blogs. While this type of information can be useful for general threat intelligence, it may not always be reliable or specific to the financial services industry.
Option D (common vulnerability and exposure bulletins) provides information about specific vulnerabilities in software or hardware, but does not necessarily provide broader threat intelligence or information specific to the financial services industry.
In contrast, information sharing and analysis membership (option C) refers to organizations that have formed partnerships to share threat intelligence and best practices among their members. These organizations typically focus on specific industries or sectors, such as financial services. By being a member, a security analyst can have access to relevant and timely threat information that is specific to the financial services industry, which can help them to better protect their organization. Therefore, this option is the best choice for a security analyst seeking relevant and timely threat information concerning the financial services industry.
