Data security and controlling interruption of the data communication path in the session mode

A countermeasure for information security threats with autonomous controlling physical interruption of the data communications path by a secured schedule is discussed. The method is effective within a concept of the defense in depth during functioning of many computerized systems, which have sufficient amount of episodic communications with network structural elements or service users. In this case, access of the node to the network is necessary and sufficient in the session mode in specific and limited intervals of time, between which access may be denied. The method is of independent importance, as another defensive layer, but in these conditions, it increases the effectiveness of other methods of the defense in depth, the likelihood of passing through which depends on the search time of the protected site under the possible attacks or observation. The effectiveness of the discussed method was performed. Client-server software was written on C# to implement this method.
