A computer-implemented method includes identifying a data transmission session associated with a display-oriented data transmission scheme; identifying an outbound data stream associated with the data transmission session; and determining one or more protected fields associated with the outbound data stream. The computer-implemented method further includes determining a client attempt to write to at least one of the one or more protected fields; and in response to determining said client attempt, determining an intrusion detection report. A corresponding computer program product and computer system are also disclosed.

Detecting intrusion attempts in data transmission sessions

Aspects of the present invention disclose a method, computer program product, and system for determining a number of allowed lists and initiating a change in a number of lists. The method includes receiving a defined list count of a plurality of lists of a coupling facility structure, monitoring list usage by the coupling facility structure, determining that additional lists are required by the coupling facility structure above the defined list count, based on the monitored list usage. The method includes, in response to determining that additional lists are required by the coupling facility structure, determining a new number of lists, where the new number of lists are based on an availability of space for the new number of lists on the coupling facility structure and the new number of lists exceeds the defined list count. The method includes rebuilding coupling facility structure based upon the determined new number of lists.
