Azure ARM Misconfiguration: Improper Compute VM Access Control

Bicep
JSON

Abstract

このテンプレートは、SSH 基本認証を許可する VM を定義します。

Explanation

基本認証によって保護されたシステムは、潜在的な脆弱性を攻撃者に提供します。攻撃者は、ブルートフォース、推測、またはソーシャルエンジニアリングによって、パスワード (特に、弱いパスワード) を侵害する可能性があります。

例 1: 次の例は、SSH 基本認証を許可する VM を示しています。


{
    "resources": [
        {
            "type": "Microsoft.Compute/virtualMachines",
            "apiVersion": "2021-03-01",
            "name": "[variables('vmName')]",
            "location": "[parameters('location')]",
            ...
            "osProfile": {
                "computerName": "[variables('vmName')]",
                "adminUsername": "[parameters('adminUsername')]",
                "linuxConfiguration": {
                    "disablePasswordAuthentication": false
                }
            },
            ...
        }
    ]
