Translation guide
A vulnerability in a system that can be exploited. In Japanese, this is most commonly expressed with セキュリティホール, a direct loanword, or 脆弱性 when referring to software vulnerabilities. For physical security gaps, other terms are used.
A flaw in software, a network, or a computer system that allows unauthorized access or attacks.
A gap in physical security, such as an unlocked door, a blind spot in surveillance, or a weak point in a fence.
Literally 'hole in security'. Used for physical security gaps, like a blind spot in surveillance or an unlocked entrance. More concrete than 脆弱性.
