A web server has been deployed in a public IaaS provider and has been assigned the public IP address of 72.135.10.100. Users are now reporting that when they browse to the website, they receive a message indicating the service is unavailable. The cloud administrator logs into the server, runs a netstat command, and notices the following relevant output:
Which of the following actions should the cloud administrator take to resolve the issue?
The netstat output shows multiple connections from the IP address 17.3.130.3 to various ports on the web server, all in the TIME_WAIT state. This indicates that the web server is repeatedly handling requests from this IP address, potentially flooding the service and causing it to be unavailable to other users. Configuring the Web Application Firewall (WAF) to filter requests from this specific IP address (17.3.130.3) should help mitigate this issue by blocking excessive or malicious traffic.
C is the only answer that makes sense.
