Kathleen runs a vulnerability scan, which notes that a service is running on TCP port 80. Which of the following types of service is most likely running on that port?

Although 80 and 443 are the most common HTTP ports, it is common practice to run additional web servers on port 8080 when a nonstandard port is needed. SSH would be expected to be on port 22, RDP on 3389, and MySQL on 3306.
