71            The current system for graphing i-scream data  from the i-scream
72            system is good, but proving to be unscalable and very resource
73            hungry. This is mostly due to the MySQL database backend,
74            and the vast quantity of data recorded. The new system
75            in development makes use of <a href="http://rrdtool.eu.org/">
76            RRDtool</a> to generate the graphs in realtime. This reduces
77            the peak loads of the system, and allows generation of more
78            flexible graphs. This work is nearing completetion.

82            <b>Server security</b><br><br>
83            Security was something mostly overlooked in the original stage
84            of this project (due to the academic nature of the work). However,
85            once in production use this has become an issue, and is being
86            addressed. Initially the plan is to lock down the external points
87            of access (TCP & UDP) in the server to specific hosts. In the
88            longer term, encryption of data would be nice, but would take a
89            lot more time and work.

95            The i-scream system is being tested and developed within the
96            Univeristy of Kent Computer Science department by the Systems
97            Group. This has led to many bug fixes and minor feature
98            enhancements, and will hopefully help to aid the long term
99            development of the system.
