Question
A security analyst is inspecting the results of a recent internal vulnerability scan that was performed against intranet services.

A. B. C. D.B.
The first action that the security analyst should perform after identifying a critical-rated vulnerability in the web server is to apply organizational context to the risk rating. Option B is the correct answer in this scenario.
Explanation:
- Option A is not the correct action to take at this stage. While senior management may need to be informed eventually, it is not the first step in addressing a critical vulnerability. The security analyst needs to assess the vulnerability and take appropriate steps to mitigate the risk.
- Option C is a possible action to take but it depends on the specific situation. The security analyst needs to evaluate the urgency of the patching, the impact on the organization, and the availability of vendor patches before organizing for urgent out-of-cycle patching.
- Option D is not recommended because exploiting the server can result in more damage to the system and further compromise its security. The analyst should never try to exploit a vulnerability, especially in a production system.
Therefore, the first step in addressing the critical vulnerability is to apply organizational context to the risk rating. This means the analyst should evaluate the potential impact of the vulnerability on the organization's operations, data, and reputation. For example, the analyst may consider the following factors:
- Which systems are affected by the vulnerability?
- What types of data could be exposed if the vulnerability is exploited?
- What are the consequences of a successful attack on the web server?
- What is the likelihood of a successful attack based on the organization's security controls?
By applying organizational context to the risk rating, the security analyst can make an informed decision about the urgency of the situation and the appropriate course of action. The analyst may then recommend patching the vulnerability immediately, or may advise on other mitigation strategies such as temporary workarounds or blocking access to the vulnerable service until a patch is available.
In summary, when a security analyst discovers a critical-rated vulnerability in a web server, the first action is to apply organizational context to the risk rating. This allows the analyst to evaluate the potential impact of the vulnerability and make an informed decision about how to address the risk.
