入門編：検知とインシデント対応

検知とインシデント対応は、サイバーセキュリティアナリストの重要な仕事の一部です。ここでは、サイバーセキュリティの職が悪意のある脅威をどのように検証し、対応するのかを探るとともに、インシデント対応に関わるステップについても詳しくご説明します。

ネットワークの監視と分析

ここでは、一般的にパケットスニッファーと呼ばれるネットワーク解析ツールを探求します。具体的には、ネットワークをスニッフィングし、パケットを解析して悪意のある脅威がないかどうかを調べます。また、キャプチャしたパケットの内容を分析するためのフィルタリングコマンドを作成します。

インシデント調査と対応

ここではインシデントの検知、調査、分析、対応の各段階におけるさまざまなプロセスや手順について学び、不審なファイルに対するハッシュ化の詳細を分析します。また、検知と対応の段階におけるドキュメントと証拠収集の重要性を学びます。最後に、インシデントのタイムラインを再構築するために、アーティファクトをマッピングすることで、インシデントの時系列を推測します。

IDS、SIEM ツールを使いネットワークトラフィックやログを取得する

ここでは、不正侵入検知システム（IDS）およびSIEM（セキュリティ情報イベント管理）システムにおけるログとその役割について学びます。これらのシステムがどのように攻撃を検知するかを学び、IDS および SIEM の製品をいくつかご紹介します。さらに、IDS の基本的なルールを作成し、悪意のあるネットワークトラフィックに対するアラートを設定します。
