But as soon as the threat is passed, the entrance is open again, and maybe there are situations in computer security where operating costs are low enough that we could just block access temporarily in response to an immediate threat, and then open it again, instead of trying to build a permanent firewall or fortress.
No čim prijetnja prođe, ulaz se ponovno otvara, i možda postoje situacije u računalnoj sigurnosti gdje su operativni troškovi dovoljno niski pa bismo privremeno zablokirali prilaz kao odgovor na trenutnu prijetnju, i onda ga opet otvorili, umjesto da gradimo trajni vatrozid ili utvrdu.
