A. B. C. D.A.
When conducting a vulnerability assessment of a router, it is important to minimize system interaction as much as possible to reduce the risk of disrupting normal network operations. To achieve this, one can employ the following methods:
A. Download the configuration: This method involves obtaining a copy of the router's configuration file without interacting with the router itself. This can be done by accessing the router's backup configuration file, which can be saved on a TFTP (Trivial File Transfer Protocol) server. By analyzing the configuration file offline, vulnerabilities can be identified without the need for direct interaction with the router.
B. Run a credentialed scan: This method involves using valid credentials to access the router's administrative interface and conducting a vulnerability scan. By using valid credentials, the scanner can obtain a more complete picture of the router's configuration and identify vulnerabilities that may not be visible through other methods.
C. Conduct the assessment during downtime: This method involves conducting the vulnerability assessment when the router is not in use, such as during scheduled maintenance windows or off-hours. This allows the assessment to be conducted without impacting normal network operations.
D. Change the routing to bypass the router: This method involves changing the network routing temporarily to bypass the router being assessed. By redirecting traffic to another path, the router can be assessed without impacting normal network operations.
Out of the four options, option A (Download the configuration) is the method that minimizes system interaction the most because it does not require any direct interaction with the router. Instead, it involves analyzing a backup configuration file, which can be done offline. Therefore, option A is the correct answer to the question.
