When an engineer receives an alert of a zero-day vulnerability affecting desktop phones, the first step that the engineer should take is to initiate a triage meeting to acknowledge the vulnerability and its potential impact. This is option A.
Triage is the process of quickly determining the severity and impact of an incident or vulnerability. The purpose of this meeting is to identify the affected devices and the potential impact on the organization's operations. During the meeting, the engineer should gather information about the affected devices, the nature of the vulnerability, and the potential risks and consequences of a successful attack.
Once the impact has been assessed, the engineer can then determine the appropriate course of action. This may include determining the company usage of the affected products (option B), searching for a patch to install from the vendor (option C), and/or implementing restrictions within the VoIP VLANS (option D).
Option B involves determining whether the organization is using the affected products, and if so, how extensively they are being used. This information can help the engineer assess the potential impact of the vulnerability on the organization and prioritize the remediation efforts.
Option C involves searching for a patch to install from the vendor. This may involve contacting the vendor directly or checking the vendor's website for available updates or patches. Installing a patch is a common method of remediation for known vulnerabilities, as it addresses the root cause of the vulnerability.
Option D involves implementing restrictions within the VoIP VLANS. This may include configuring access control lists (ACLs) or implementing port security to restrict access to the affected devices. This option may be used in conjunction with other remediation efforts, such as installing a patch.
In summary, after receiving an alert of a zero-day vulnerability affecting desktop phones, the engineer should initiate a triage meeting to assess the potential impact of the vulnerability on the organization. Based on this assessment, the engineer can then determine the appropriate course of action, which may include determining company usage of the affected products, searching for a patch to install from the vendor, and/or implementing restrictions within the VoIP VLANS.
