Dans les années 1950 et 1960, la NSA était très inquiète de voir des employés révéler des secrets. Pour les sensibiliser, elle avait d’ailleurs créé des affiches dont voici quelques exemples qui viennent d’être déclassifiés:
From a FOIA request, over a hundred old NSA security awareness posters. Here are the BBC’s favorites. Here are Motherboard’s favorites. I have a related personal story. Back in 1993, during the first Crypto Wars, I and a handful of other academic cryptographers visited the NSA for some meeting or another.
The National Security Agency isn’t just concerned with spying on the bad guys-and sometimes the good guys-or creating powerful hacking tools to pwn the world’s networks. The NSA has always been worried about employees spilling its own secrets, Edward Snowden-style.
Long before it was at the centre of a huge spying scandal, the US National Security Agency had the communist threat to deal with – and wanted to make sure its staff did not spill secrets. A vast archive of posters, apparently for display at the spy agency’s offices, has been posted online thanks to a freedom of information request from governmentattic.org.
