At its simplest level the most obvious feature of the Walled Garden is the Wall. Walls have all sorts of connotations for us, especially at this moment in history, but they begin with protection. Being surrounded by a wall gives us a feeling of security and control over who or what can gain access inside and control as to what and who leaves. In its original use for a real garden the wall was much more about protection, shelter and providing the right environment for the plants and crops. The surrounding wall warms in the sun and raises the ambient temperature for plants in the north of the garden, it provides shelter from prevailing and strong winds and it organises the land separating it for management.

Do the walls around our information systems share these nurturing properties?
