SSL、httpsの証明書の安全性、期限をチェック、確認するツール、サイトを調べてみました。
Qualys SSL LABS SSL Server Testでhttpsの安全性、期限を確認
正しいSSL証明書を利用している場合でも、Webサーバーのアップグレードが正しく行われていなかったり、利用する暗号化の方法が古かったりすると、SSLの目的が果たせなくなります。
また、関連アプリケーションで新しい脆弱性が発見されることも少なくありません。
そのため、機密性・安全性を確保するために運営しているSSLサイトの定期的な安全性のチェックは必須です。
しかし、SSLサイトが正しく機能するための要素は複数あり、一般的なサイト管理者には理解しにくい要素も少なくありません。
SSLサイト評価の定期的な評価に使えるのが Qualys SSL LABS SSL Server Test です。
Qualys SSL LABS SSL Server Test は誰でも無料で利用できます。
