20140259160 | DETECTION OF A THREAT IN A COMMUNICATIONS NETWORK - Disclosed is a method for detecting a threat against a host computer coupled to the front-end computer. A communication connection is established between the host computer and a source computer with a handshake procedure through a front-end computer. Application data is received in the front-end computer from the source computer. The received application data is returned from the front-end computer to the source computer. It is monitored in the front-end computer if a predetermined message is received from the source computer in response to the return of the application data. If the predetermined message is received in the front-end computer, it is determined that the source computer is a trusted communication party, But if the predetermined message is not received, the source computer is determined as a threat. The invention relates also to computing device implementing the method and a computer program product. | 09-11-2014 |
