Description
Connectors are how Tomcat receives requests over a network port, passes them to hosted web applications via HTTP or AJP and then sends back the results to the requestor. A port and a protocol are tied to each connector. Only connectors approved by the ISSO must be installed. ISSO review will consist of validating connector protocol as being secure and required in order for the hosted application to operate. The ISSO will ensure that unnecessary or insecure connector protocols are not enabled. The ISSO will provide documented approval for each connector that will be maintained in the System Security Plan (SSP).
