Host trust report based filtering mechanism in a reverse firewall

A computer implemented method to report a bad host, the computer implemented method comprising:

• a receiver host receiving a packet from a sender host;
• the receiver host detecting that the packet contains suspect hostile content;
• the receiver host transmitting a negative trust report to a reverse firewall;
• the receiver host receiving a request for a demanded positive trust report from the reverse firewall, wherein the reverse firewall connects a first network hosting the receiver host to a second network hosting the sender host that is described in the request for the demanded positive trust report;
• responsive to receiving the request for the demanded positive trust report, incrementing a count;
• the receiver host determining whether the count is below a threshold number of demanded positive trust reports;
• responsive to a determination that the count is below the threshold number of demanded positive trust reports, the receiver host determining whether the sender host is marked good;
• and
• responsive to a determination that the sender host is marked good, the receiver host transmitting a positive trust report to the reverse firewall.
