SSMC web server must restrict connections from nonsecure zones.
An XCCDF Rule
Description
<VulnDiscussion>Remote access to the web server is any access that communicates through an external, non-organization-controlled network. Remote access can be used to access hosted applications or to perform management functions. A web server can be accessed remotely and must be capable of restricting access from what the DOD defines as nonsecure zones. Nonsecure zones are defined as any IP, subnet, or region that is defined as a threat to the organization. The nonsecure zones must be defined for public web servers logically located in a DMZ, as well as private web servers with perimeter protection devices. By restricting access from nonsecure zones, through internal web server access list, the web server can stop or slow denial of service (DoS) attacks on the web server.

Configure SSMC to block access from DOD-defined nonsecure zones by enabling remote host access control by doing the following:
1. Log on to SSMC appliance as ssmcadmin. Press "X" to escape to general bash shell.
2. Configure all hosts to which network traffic needs to be allowed by setting these two properties in /ssmc/conf/security_config.properties.
