セキュアソフトウェア開発：実装 from edX

現代のソフトウェアは常に攻撃を受けていますが、多くのソフトウェア開発者は、それらの攻撃に効果的に対処する方法を教わったことがありません。このコースでは、この問題を解決するために、セキュアなソフトウェアを開発するための基本的な知識を解説します。このコースは、ソフトウェア開発者、DevOpsプロフェッショナル、ソフトウェア技術者、Webアプリケーション開発者、およびセキュアなソフトウェアの開発方法を学ぶことに関心のある人を対象としており、情報セキュリティを改善するために、限られたリソースでも実行可能な実践的なステップに重点を置いています。このコースでは、ソフトウェア開発者が、攻撃を成功させるのが格段に難しいシステムを開発し、維持すること、攻撃が成功した場合の被害を減らすこと、潜在的な脆弱性を速やかに修復できるよう対応を迅速化することができるようになることを目指します。

このコースでは、入力検証（なぜ許可リストを使用し、拒否リストを使用しないかなど）、セキュアなデータ処理、他のプログラムの呼び出し、出力の送信、エラー処理など、実装上の重要な問題に焦点を当てます。このコースでは、最も一般的な種類の攻撃に対処するために、（開発者として）あなたが取ることができる実践的なステップに重点を置いています。

このコースは、「セキュアソフトウェア開発の基礎」のプロフェッショナル認定プログラムの3つのコースのうちの2つ目のコースで、オープンソースのエコシステムのセキュリティにフォーカスしたLinux FoundationのプロジェクトであるOpen Source Security Foundation（OpenSSF）によって開発されたものです。
