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.
Tapi begitu ancaman berlalu, pintu masuk dibuka lagi. Dan mungkin ada situasi dalam keamanan komputer di mana biaya operasional cukup rendah sehingga kita bisa menutup akses sementara sebagai respons terhadap ancaman, kemudian membukanya lagi, daripada berusaha membangun firewall atau benteng permanen.
