Private Endpoints
Configure private endpoints for enhanced security: ``powershell
Create private endpoint for storage
$privateEndpointConnection = New-AzPrivateLinkServiceConnection
-Name "pe-storage-connection"
-PrivateLinkServiceId $storageAccount.Id
-GroupId "blob"New-AzPrivateEndpoint Production Environments
Global Organizations Tier 1 - Critical (Every backup)
Tier 2 - Important (Daily) Tier 3 - Standard (Weekly) 1. Separate Service Principals
- One for portal authentication
- One for backup operations
- One for drift detection
- Principle of least privilege 2. Secret Rotation
-ResourceGroupName "rg-tenuvault"
-Name "pe-storage"
-Location "eastus"
-Subnet $subnet

Scheduling Best Practices
Optimal Backup Windows
Choose backup times based on your timezone and usage patterns:
Stagger backups across regions:
Frequency Recommendations
Environment Type Frequency Rationale Production Every 12 hours Balance between data protection and resource usage UAT/Staging Daily Less critical, still needs protection Development Weekly Mainly for configuration templates Pilot Programs Every 6 hours Rapid changes, need quick recovery Static Configs Monthly Rarely change, archive purposes Backup Scope Optimization
Critical vs Non-Critical
Prioritize critical configurations:
Implement smart incremental backups:
Incremental Backup Strategy
Daily full backup
if ($DayOfWeek -eq "Sunday") {
Backup-IntuneConfiguration -Type Full
} else {
# Incremental on other days
Backup-IntuneConfiguration -Type Incremental -Since $LastBackup
}
Retention Policies
Tiered Retention Model
Implement grandfather-father-son rotation:Automated Lifecycle Management
Configure storage lifecycle policies:
Security Best Practices
Authentication and Authorization
Service Principal Management
Best practices for service principals:
-EndDate (Get-Date).AddDays(90)
# Update Key Vault
Set-AzKeyVaultSecret
-VaultName "kv-tenuvault"
-Name "ClientSecret"
-SecretValue (ConvertTo-SecureString $newSecret.SecretText -AsPlainText -Force)
3. Certificate-Based Authentication
Prefer certificates over secrets:
-Subject "CN=TenuVault"
-CertStoreLocation "Cert:\CurrentUser\My"
-KeyExportPolicy Exportable
-KeySpec Signature
-KeyLength 2048
-KeyAlgorithm RSA
-HashAlgorithm SHA256
Role-Based Access Control
Implement proper RBAC:
TenuVault Administrator
- Full portal access
- Backup/restore permissions
- Configuration management
- User management
TenuVault Operator
- View backups
- Trigger manual backups
- View reports
- No restore permissions
TenuVault Viewer
- Read-only access
- View reports
- No operational permissions
Data Protection
Encryption Standards
At Rest
- Storage Service Encryption (SSE)
- Customer-managed keys (CMK)
- Azure Disk Encryption for VMs
In Transit
- TLS 1.2 minimum
- Certificate pinning
- Perfect forward secrecy
Backup Encryption
Additional encryption layer:
powershell
Encrypt backup before storage
$encryptedBackup = Protect-CmsMessage
-To $certificateThumbprint
-Content $backupJson
Network Security
Firewall Rules
Configure storage firewall:
powershell
Allow only specific IPs
Update-AzStorageAccountNetworkRuleSet
-ResourceGroupName "rg-tenuvault"
-Name "sttenuvault"
-DefaultAction Deny
-IPRule @{IPAddressOrRange="203.0.113.0/24"}
Private Endpoints
Implement private endpoints for all services:
- Storage accounts
- Key Vault
- SQL databases (if used)
- App Services
Storage Optimization
Compression Strategies
Compression Levels
Balance speed vs size:Level Compression Ratio Speed Use Case
None 1:1 Fastest Real-time access needed
Fast 2:1 Fast Default for most
Normal 3:1 Moderate Standard backups
Maximum 4:1 Slow Long-term archives
Implementation
powershell
Compress before storage
$compressed = [System.IO.Compression.GZipStream]::new(
$outputStream,
[System.IO.Compression.CompressionLevel]::Optimal
)
Deduplication
Policy-Level Deduplication
Store unique policies once:
powershell
Calculate hash for deduplication
$policyHash = Get-FileHash -InputStream ([System.IO.MemoryStream]::new([System.Text.Encoding]::UTF8.GetBytes($policyJson))) -Algorithm SHA256Check if already exists
if (-not (Test-BlobExists -Hash $policyHash)) {
Upload-Blob -Content $policyJson -Metadata @{Hash=$policyHash}
}
Cross-Tenant Deduplication
For multi-tenant deployments:
- Shared policy repository
- Reference counting
- Copy-on-write for modifications
Storage Tiers
Tier Selection Matrix
Age Access Frequency Recommended Tier Cost/GB
0-30 days Daily Hot $0.0184
31-90 days Weekly Cool $0.01
91-180 days Monthly Cool $0.01
180+ days Rarely Archive $0.00099
Automated Tiering
powershell
Move to appropriate tier based on age
$blobs = Get-AzStorageBlob -Container "backups"
foreach ($blob in $blobs) {
$age = (Get-Date) - $blob.LastModified
if ($age.Days -gt 180) {
$blob.ICloudBlob.SetStandardBlobTier("Archive")
} elseif ($age.Days -gt 30) {
$blob.ICloudBlob.SetStandardBlobTier("Cool")
}
}
Performance Optimization
API Optimization
Batch Operations
Minimize API calls:
powershell
Bad: Individual calls
foreach ($policy in $policies) {
Get-IntunePolicy -Id $policy.Id
}Good: Batch request
$batch = @{
requests = $policies | ForEach-Object {
@{
id = $_.Id
method = "GET"
url = "/deviceManagement/deviceConfigurations/$($_.Id)"
}
}
}
Invoke-MgGraphRequest -Method POST -Uri "https://graph.microsoft.com/v1.0/
$batch" -Body $batch
Pagination Handling
Efficient pagination:
while ($nextLink) { $response = Invoke-MgGraphRequest -Uri $nextLink $allPolicies += $response.value $nextLink = $response.'@odata.nextLink' }
Caching Strategies
Redis Cache Implementation
For frequently accessed data:
Cache configuration
$redis = Connect-RedisCache -ConnectionString $redisConnectionCache backup metadata
$cacheKey = "backup:metadata:$tenantId" $cached = Get-RedisCache -Key $cacheKeyif (-not $cached) { $metadata = Get-BackupMetadata -TenantId $tenantId Set-RedisCache -Key $cacheKey -Value $metadata -Expiry 3600 }
Local Caching
Browser-side caching:
function getCachedData(key) { const cached = cache.get(key); if (cached && Date.now() - cached.timestamp < cacheTimeout) { return cached.data; } return null; }
Database Optimization
Index Strategy
Key indexes for performance:
-- Drift detection queries CREATE INDEX idx_drift_severity ON drift_events(severity, detected_at DESC); CREATE INDEX idx_drift_tenant ON drift_events(tenant_id, detected_at DESC);
