Design of the Cyber Security Operations Centre

The public opening of the Cyber Security Operations Centre (CSOC) at the Defence Signals Directorate provides a rare insight into the design of an Australian military operations centre. The Minister for Defence announced the centre would have a staff of 51 to 130.

One photo shows a close-up of an operator at a console. There are three wide format Dell monitors, each of about 24 Inches. The monitors are simply placed on the desktop using their supplied stands (no multi-monitor mounting is used). A standard keyboard and mouse are used. A Cisco Unified IP Phone (7970G or similar) digital telephone handset is located alongside the screens. In the background is a large video wall screen with two smaller flat screen displays and LED world clocks. There is a railing showing a balcony and second level with a glass wall and door (presumably offices).

Underneath are the two flat panel wide screens showing BBC World News. The flat panels have four LED world clocks to there left.

The design of the room appears symmetrical, with a central walkway about 1.2 m wide. Individual rectangular adjustable height office desks 1600 x 800 mm are used. Three rows of desks are visible, with three desks in each row, about 1200 mm between the rows. There is one operator, with two screens (some three screens) and a phone per desk. Free standing drawer units are under some desks. The back of the room shows a built in semicircular desk with two monitors.

Assuming the room is symmetrical, it would have 19 operator workstations. The room is about 13 m wide and 10 m deep, with a double height ceiling of about 6 m. This provides a generous 7 square metres per operator.

Clearly 51 staff could not fit in this area. Assuming that the visible area is surrounded by standard offices on two levels of three sides, that would provide an additional 440 square metres of space. This would provide a reasonable 11 square metres of space per staff member, for 51 staff.

The design of the room does not appear optimal for space utilisation or group work. The desks, at 800 mm, are deeper than needed (smaller desks could double the room capacity). The use of two screens per workstation creates a situation where the operator has to look either to the left or right, not straight ahead. There are only limited gaps between the screens cutting the operators off from those in front and behind. Also the desk rows are straight, reducing the ability of the operators to see others. Narrower semicircular rows of desks would provide a better result. These could be fabricated simply (height adjustment is not used in such centres, as is evident from the photographs). Also it might be better to provide each operator with just one large monitor (up to 30 inch).
