  • A little bit of perspective from Finland, as a neighbour of Russia. We have suffered from old landmines, so we are pretty familiar with the downsides. Finland joined the Ottawa Treaty in 2012. That has been largely seen as a mistake. If we would deploy mines in a new war, the locations would be documented well so that they could be disarmed with no harm to our civilians. And as a small country, we are not going to invade any other country and leave mines there after a war.

    So there isn’t really any benefit to our civilians. But we lost one cost effective way to defend against an aggressive neighbour who has superior numbers of people to send as cannon fodder.











  • Passwords will be brute forced if it can be done offline.

    Private SSH keys should never leave a machine. If a key gets compromised without you knowing, in worst case you will revoke the access it has once the machine’s lifespan is over. If you copy around one key, it may get compromised on any of the systems, and you will never revoke the access it has.

    And you may not want to give all systems the same access everywhere. With one key per machine, you can have more granularity for access.
