yum によるLinuxセキュリティパッチ更新

4月 1, 2021AmazonLinux_CentOS,EC2,OperatingSystem,セキュリティ関連

概要

  • 今回は、yumコマンドを使ったLinux OS のセキュリティパッチ更新方法をまとめます。yum update コマンドはシステム構築で頻繁に使用しますが、サービス開始後のシステムではインパクトが大きいかと思います。一方で、日々公開される脆弱性の情報に対応するため、セキュリティパッチの更新は必須です。
  • 以下に紹介するセキュリティ関連のyumコマンドを使用することで、Linux OS全体ではなく、セキュリティパッチのみを更新することが可能です。

 

OS を最新の状態に保つ

よく使う セキュリティ関連のyumコマンド

  • yum list updates --security  (= yum check-update --security)
    • 利用可能なセキュリティアップデートのパッケージ一覧を取得します。
  • yum updateinfo
    • 利用可能なセキュリティアップデートのサマリーを表示します。
  • yum updateinfo list  (= yum updateinfo security)
    • 利用可能なセキュリティアップデートを一覧で表示します。
  • yum updateinfo all
    • 利用可能なセキュリティアップデートの情報をfullで表示します。
  • yum updateinfo ALAS2-yyyy-nnnn
    • 特定のセキュリティアップデートに関する情報を表示します。
  • sudo yum update --security
    • 利用可能なセキュリティアップデートを更新する。
  • sudo yum update --advisory=ALAS2-yyyy-nnnn
    • 特定のセキュリティアップデートを更新する。
