AMI
AWS東京リージョンで 公開されている Amazon Linux 2023 のAMI (al2023-ami-2023.0.20230222.1-kernel-6.1-x86_64) を利用しました。
Amazon マシンイメージ (AMI) のダッシュボードを利用する場合、以下検索条件で Amazon Linux 2023 の公式AMIが抽出可能でした。
- 所有者: 137112412989
- AMI名: 「al2023」を含む
セッションマネージャ
Amazon Linux 2023 のRC0のAMIでは、SSM Agent がデフォルトでインストールされるようになりました。
EC2インスタンスの起動時、IAM インスタンスプロフィール として、マネージドポリシー「AmazonSSMManagedInstanceCore」を含む IAMロールを利用する事で、 セッションマネージャを利用したリモート接続が可能になりました。
SE Linux
SE Linux は「Permissive」。監査ログ記録のみ実施するモードで有効化されていました。
Amazon Linux 2022 のプレビュー版のデフォルトは「Enforcing」、SE Linux のポリシーが強制される設定でした。
sh-5.2$ getenforce Permissive sh-5.2$ sestatus SELinux status: enabled SELinuxfs mount: /sys/fs/selinux SELinux root directory: /etc/selinux Loaded policy name: targeted Current mode: permissive Mode from config file: permissive Policy MLS status: enabled Policy deny_unknown status: allowed Memory protection checking: actual (secure) Max kernel policy version: 33
