Fewer Bricks Each Year

The Firewall Glyph in One Operations Archive's Hand-Drawn Network Diagrams, 1996–2021

A research poster from the School of Underlying Conditions reads the brick-wall sign for a firewall, drawn on 288 of 412 hand-drawn network diagrams in a decommissioned security operations centre's incident binders between 1996 and 2021, as an art historian reads a motif. The median glyph thins from six brick courses to one and a written label arrives as the bricks go, while the closed line drawn round the inside network outlasts the wall drawn across it by about a decade.
