+### blueprints/gh-aspnet-webapp/bicep/resources.bicep
+
+#### [CRITICAL] NSG-001: Web Application Not Enforcing HTTPS
+- **Resource:** `Microsoft.Web/sites` (webApp)
+- **Line:** 45-75
+- **Issue:** Web application was missing `httpsOnly: true` property, allowing unencrypted HTTP traffic
+- **Impact:** Data in transit exposed to eavesdropping and man-in-the-middle attacks
+- **Control Mapping:** CIS Azure 9.2, NIST SC-8, Azure Security Benchmark NS-8
+- **Remediation:** Added `httpsOnly: true` to enforce HTTPS-only connections
+
+```diff
+   properties: {
+     serverFarmId: appServicePlan.id
++    httpsOnly: true
+     siteConfig: {
+```
+
+#### [HIGH] ENC-001: Weak TLS Configuration
+- **Resource:** `Microsoft.Web/sites` (webApp)
+- **Line:** 56
+- **Issue:** Minimum TLS version not specified, potentially allowing TLS 1.0/1.1
+- **Impact:** Vulnerable to downgrade attacks and weak cipher exploitation
+- **Control Mapping:** CIS Azure 9.3, NIST SC-8, Azure Security Benchmark DP-3
+- **Remediation:** Set minimum TLS version to 1.2
+
+```diff
+     siteConfig: {
++      minTlsVersion: '1.2'
++      ftpsState: 'Disabled'
++      alwaysOn: true
+       acrUseManagedIdentityCreds: true
+```
+
+#### [HIGH] NSG-002: Azure Container Registry Publicly Accessible
+- **Resource:** `Microsoft.ContainerRegistry/registries` (acr)
+- **Line:** 20-29
+- **Issue:** ACR was accessible from public internet without network restrictions
+- **Impact:** Unauthorized access to container images; potential data exfiltration
+- **Control Mapping:** CIS Azure 9.9, NIST SC-7, Azure Security Benchmark NS-1
+- **Remediation:** Disabled public network access; enabled Azure Services bypass
+
+```diff
+   properties: {
+     adminUserEnabled: false // Use managed identity instead
++    publicNetworkAccess: 'Disabled'
++    networkRuleBypassOptions: 'AzureServices'
+   }
+```
+
+#### [MEDIUM] MON-001: FTPS Not Disabled
+- **Resource:** `Microsoft.Web/sites` (webApp)
+- **Issue:** FTPS state not explicitly set, leaving legacy upload methods enabled
+- **Impact:** Weak legacy protocols increase attack surface
+- **Control Mapping:** Azure Security Benchmark NS-8

+
+### blueprints/sample-web-app/bicep/main.bicep
+
+#### [HIGH] ENC-002: SQL Database Missing Transparent Data Encryption
+- **Resource:** `Microsoft.Sql/servers/databases` (sqlDatabase)
+- **Line:** 163-174
+- **Issue:** TDE not explicitly enabled for SQL Database
+- **Impact:** Data at rest not encrypted; compliance violation
+- **Control Mapping:** CIS Azure 4.1.2, NIST SC-28, Azure Security Benchmark DP-4, PCI-DSS 3.4
+- **Remediation:** Added TDE configuration resource
+
+```bicep
+/* SQL Database Transparent Data Encryption */
+resource sqlDatabaseTDE 'Microsoft.Sql/servers/databases/transparentDataEncryption@2023-08-01-preview' = {
+  parent: sqlDatabase
+  name: 'current'
+  properties: {
+    state: 'Enabled'
+  }
+}
+```
+
+#### [HIGH] MON-002: SQL Server Auditing Not Configured
+- **Resource:** `Microsoft.Sql/servers` (sqlServer)
+- **Line:** 138-157
+- **Issue:** No auditing configured for SQL Server events
+- **Impact:** Unable to detect or investigate security incidents; compliance violation
+- **Control Mapping:** CIS Azure 4.1.3, NIST AU-2, Azure Security Benchmark LT-4, PCI-DSS 10.2
+- **Remediation:** Enabled SQL Server auditing with 90-day retention
+
+```bicep
+/* SQL Server Auditing */
+resource sqlServerAudit 'Microsoft.Sql/servers/auditingSettings@2023-08-01-preview' = {
+  parent: sqlServer
+  name: 'default'
+  properties: {
+    state: 'Enabled'
+    isAzureMonitorTargetEnabled: true
+    retentionDays: 90
+    auditActionsAndGroups: [
+      'SUCCESSFUL_DATABASE_AUTHENTICATION_GROUP'
+      'FAILED_DATABASE_AUTHENTICATION_GROUP'
+      'BATCH_COMPLETED_GROUP'
+    ]
+  }
+}
+```
+
+#### [MEDIUM] IAM-001: SQL Server Missing Managed Identity
+- **Resource:** `Microsoft.Sql/servers` (sqlServer)
+- **Line:** 138-146
+- **Issue:** SQL Server not configured with managed identity for authentication
+- **Impact:** Limited ability to use passwordless authentication mechanisms
+- **Control Mapping:** CIS Azure 4.1.1, Azure Security Benchmark PA-7
+- **Remediation:** Added system-assigned managed identity and optional Azure AD admin configuration
+
+```diff
+ resource sqlServer 'Microsoft.Sql/servers@2023-08-01-preview' = {
+   name: sqlServerName
+   location: location
++  identity: {
++    type: 'SystemAssigned'
++  }
+   properties: {
+     administratorLogin: 'sqladmin'
++    administrators: !empty(sqlAdminObjectId) && !empty(sqlAdminLogin) ? {
++      administratorType: 'ActiveDirectory'
++      azureADOnlyAuthentication: false
++      login: sqlAdminLogin
++      principalType: 'User'
++      sid: sqlAdminObjectId
++      tenantId: subscription().tenantId
++    } : null
+```
+
+**Note:** Azure AD admin is now optional via parameters. When `sqlAdminObjectId` and `sqlAdminLogin` parameters are provided, Azure AD authentication is configured. Otherwise, SQL authentication is used with the expectation that the password is securely managed via Key Vault during deployment.
+
+#### [MEDIUM] MON-003: Key Vault Missing Diagnostic Settings
+- **Resource:** `Microsoft.KeyVault/vaults` (keyVault)
+- **Line:** 60-78
+- **Issue:** No diagnostic settings configured for Key Vault audit logging
+- **Impact:** Key Vault access events not logged; unable to detect unauthorized access
+- **Control Mapping:** CIS Azure 5.1.5, NIST AU-2, Azure Security Benchmark LT-4
+- **Remediation:** Added diagnostic settings with Log Analytics integration
+
+```bicep
+resource keyVaultDiagnostics 'Microsoft.Insights/diagnosticSettings@2021-05-01-preview' = {
+  name: 'kv-diagnostics'
+  scope: keyVault
+  properties: {
+    workspaceId: logAnalytics.id
+    logs: [
+      {
+        category: 'AuditEvent'
+        enabled: true
+        retentionPolicy: {
+          enabled: true
+          days: 90
+        }
+      }
+    ]
+    metrics: [
+      {
+        category: 'AllMetrics'
+        enabled: true
+      }
+    ]
+  }
+}
+```
+
+#### [MEDIUM] MON-004: SQL Server Missing Diagnostic Settings
+- **Resource:** `Microsoft.Sql/servers` (sqlServer)
+- **Issue:** No diagnostic settings for SQL Server metrics and security events
+- **Impact:** Limited visibility into SQL Server health and security events
+- **Control Mapping:** Azure Security Benchmark LT-4
+- **Remediation:** Added diagnostic settings for SQL security audit events
+
+#### [MEDIUM] MON-005: App Service Missing Diagnostic Settings
+- **Resource:** `Microsoft.Web/sites` (appService)
+- **Issue:** No diagnostic settings for application logs and HTTP traffic
+- **Impact:** Difficult to troubleshoot issues and detect anomalous behavior
+- **Control Mapping:** Azure Security Benchmark LT-4
+- **Remediation:** Added comprehensive App Service logging
+
+```bicep
+resource appServiceDiagnostics 'Microsoft.Insights/diagnosticSettings@2021-05-01-preview' = {
+  name: 'app-diagnostics'
+  scope: appService
+  properties: {
+    workspaceId: logAnalytics.id
+    logs: [
+      { category: 'AppServiceHTTPLogs', enabled: true }
+      { category: 'AppServiceConsoleLogs', enabled: true }
+      { category: 'AppServiceAppLogs', enabled: true }
+      { category: 'AppServiceAuditLogs', enabled: true }
+    ]
+  }
+}
+```
+
+#### [LOW] MON-006: Log Analytics Retention Below Recommended Duration
+- **Resource:** `Microsoft.OperationalInsights/workspaces` (logAnalytics)
+- **Line:** 29-37
+- **Issue:** Retention set to 30 days, below recommended 90 days for security logs
+- **Impact:** Limited forensic investigation window; compliance risk
+- **Control Mapping:** CIS Azure 5.1.1, Azure Security Benchmark LT-5
+- **Remediation:** Increased retention to 90 days
+
+```diff
+   properties: {
+     sku: {
+       name: 'PerGB2018'
+     }
+-    retentionInDays: 30
++    retentionInDays: 90
+   }
+```
