Air traffic control has had analog (paper strips) methods in place ever since computerised flight tracking was introduced for the simple reason that systems go down. Does your incident response plan have provision for quill and parchment or other analog methods?…:
It’s been reported that the US is very close to improving power grid security by mandating the use of “retro” (analog, manual) technologies on US power grids as a defensive measure against foreign cyber-attacks that could bring down power distribution as a result. The idea is to use “retro” technology to isolate the grid’s most important control systems, to limit the reach of a catastrophic outage. “This approach seeks to thwart even the most sophisticated cyber-adversaries who, if they are intent on accessing the grid, would have to actually physically touch the equipment, thereby making cyber-attacks much more difficult,” they said in a press release , after the bill, named the Securing Energy Infrastructure Act (SEIA), passed the Senate floor.
