"伺服器難以抵禦 BEAST 攻擊。"
Browser Exploit Against SSL/TLS (BEAST) 攻擊影響 SSL 2.0、SSL 3.0 和 TLS 1.0 通訊協議，讓不法份子將網頁瀏覽器和網站之間的 SSL 加密或 TLS 加密的工作階段的內容解密。攻擊者會利用區塊式密碼套件中的弱點。
這是用戶端側攻擊，其中的攻擊者需要控制"受害者"的瀏覽器。大多數瀏覽器難以抵禦 BEAST 攻擊。
在 BEAST 攻擊中，攻擊者扮演 man-in-the-middle (中間的男人)，使用特別設計的純文字輸入，將網頁瀏覽器和網站之間的 SSL 加密或 TLS 加密的工作階段的內容解密。此類型的攻擊允許攻擊者復原敏感資料 (例如 HTTP 身份驗證 Cookie)。
在您伺服器的 SSL/TLS 組態中，停用所有區塊式密碼套件。如果您無法在伺服器上和瀏覽器中啟用 TLS 1.2 或 TLS 1.3，僅限使用此因應措施。
