Brute force attack什麼意思

"Brute force attack" 是一個網路安全術語，指的是一種通過嘗試所有可能的密碼或密鑰組合來破解密碼保護或加密的方法。這種方法通常依賴於計算能力的提高，以加快猜測的速度。

在密碼學中，這種攻擊方式也被稱作「蠻力攻擊」或「暴力破解」。攻擊者可能會使用自動化工具來生成和測試可能的密碼組合，直到找到正確的密碼為止。這種攻擊方法雖然簡單，但往往非常有效，尤其是在用戶設定弱密碼或使用常見密碼組合的情況下。

Brute force attacks can be used to crack passwords, encryption keys, or any other security mechanism that relies on a secret key or password. They can be targeted at individual users, entire networks, or even large-scale systems like websites or databases.

To defend against brute force attacks, it is important to use strong, unique passwords, enable two-factor authentication, and use security measures such as rate limiting, which can prevent automated tools from trying an unlimited number of password combinations.
