AWS Secrets Rotation

Automate rotation of secrets, credentials, and API keys using AWS Secrets Manager and Lambda.

When to Use

Use this skill when you need to implement automated secrets rotation, manage credentials securely, or comply with security policies requiring regular key rotation.

Supported Secret Types

AWS Services

• RDS database credentials
• DocumentDB credentials
• Redshift credentials
• ElastiCache credentials

Third-Party Services

• API keys
• OAuth tokens
• SSH keys
• Custom credentials

Secrets Manager Setup

Create a Secret

# Create RDS secret
aws secretsmanager create-secret \
  --name prod/db/mysql \
  --description "Production MySQL credentials" \
  --secret-string '{
    "username": "admin",
    "password": "CHANGE_ME",
    "engine": "mysql",
    "host": "mydb.cluster-abc.us-east-1.rds.amazonaws.com",
    "port": 3306,
    "dbname": "myapp"
  }'

# Create API key secret
aws secretsmanager create-secret \
  --name prod/api/stripe \
  --secret-string '{
    "api_key": "sk_live_xxxxx",
    "webhook_secret": "whsec_xxxxx"
  }'

# Create secret from file
aws secretsmanager create-secret \
  --name prod/ssh/private-key \
  --secret-binary fileb://~/.ssh/id_rsa

Retrieve Secrets

# Get secret value
aws secretsmanager get-secret-value \
  --secret-id prod/db/mysql \
  --query 'SecretString' --output text

# Get specific field
aws secretsmanager get-secret-value \
  --secret-id prod/db/mysql \
  --query 'SecretString' --output text | \
  jq -r '.password'

# Get binary secret
aws secretsmanager get-secret-value \
  --secret-id prod/ssh/private-key \
  --query 'SecretBinary' --output text | \
  base64 -d > private-key.pem

Automatic Rotation Setup

Enable RDS Rotation

# Enable automatic rotation (30 days)
aws secretsmanager rotate-secret \
  --secret-id prod/db/mysql \
  --rotation-lambda-arn arn:aws:lambda:us-east-1:123456789012:function:SecretsManagerRDSMySQLRotation \
  --rotation-rules AutomaticallyAfterDays=30

# Rotate immediately
aws secretsmanager rotate-secret \
  --secret-id prod/db/mysql

# Check rotation status
aws secretsmanager describe-secret \
  --secret-id prod/db/mysql \
  --query 'RotationEnabled'

Lambda Rotation Function

# lambda_rotation.py
import boto3
import json
import os

secrets_client = boto3.client('secretsmanager')
rds_client = boto3.client('rds')

def lambda_handler(event, context):
    """Rotate RDS MySQL password"""
    
    secret_arn = event['SecretId']
    token = event['ClientRequestToken']
    step = event['Step']
    
    # Get current secret
    current = secrets_client.get_secret_value(SecretId=secret_arn)
    secret = json.loads(current['SecretString'])
    
    if step == "createSecret":
        # Generate new password
        new_password = generate_password()
        secret['password'] = new_password
        
        # Store as pending
        secrets_client.put_secret_value(
            SecretId=secret_arn,
            ClientRequestToken=token,
            SecretString=json.dumps(secret),
            VersionStages=['AWSPENDING']
        )
    
    elif step == "setSecret":
        # Update RDS password
        rds_client.modify_db_instance(
            DBInstanceIdentifier=secret['dbInstanceIdentifier'],
            MasterUserPassword=secret['password'],
            ApplyImmediately=True
        )
    
    elif step == "testSecret":
        # Test new credentials
        import pymysql
        conn = pymysql.connect(
            host=secret['host'],
            user=secret['username'],
            password=secret['password'],
            database=secret['dbname']
        )
        conn.close()
    
    elif step == :
        
        secrets_client.update_secret_version_stage(
            SecretId=secret_arn,
            VersionStage=,
            MoveToVersionId=token,
            RemoveFromVersionId=current[]
        )
    
     {: }

 ():
     secrets
     string
    alphabet = string.ascii_letters + string.digits + 
     .join(secrets.choice(alphabet)  _  (length))

Custom Rotation for API Keys

# api_key_rotation.py
import boto3
import requests
import json

secrets_client = boto3.client('secretsmanager')

def rotate_stripe_key(secret_arn, token, step):
    """Rotate Stripe API key"""
    
    current = secrets_client.get_secret_value(SecretId=secret_arn)
    secret = json.loads(current['SecretString'])
    
    if step == "createSecret":
        # Create new Stripe key via API
        response = requests.post(
            'https://api.stripe.com/v1/api_keys',
            auth=(secret['api_key'], ''),
            data={'name': f'rotated-{token[:8]}'}
        )
        new_key = response.json()['secret']
        
        secret['api_key'] = new_key
        secrets_client.put_secret_value(
            SecretId=secret_arn,
            ClientRequestToken=token,
            SecretString=json.dumps(secret),
            VersionStages=['AWSPENDING']
        )
    
    elif step == "testSecret":
        # Test new key
        response = requests.get(
            'https://api.stripe.com/v1/balance',
            auth=(secret['api_key'], '')
        )
        if response.status_code != 200:
            raise Exception("New key failed validation")
    
    elif step == "finishSecret":
        # Revoke old key
        old_key = json.loads(current['SecretString'])['api_key']
        requests.delete(
            f'https://api.stripe.com/v1/api_keys/',
            auth=(secret[], )
        )
        
        
        secrets_client.update_secret_version_stage(
            SecretId=secret_arn,
            VersionStage=,
            MoveToVersionId=token
        )

Rotation Monitoring

CloudWatch Alarms

# Create alarm for rotation failures
aws cloudwatch put-metric-alarm \
  --alarm-name secrets-rotation-failures \
  --alarm-description "Alert on secrets rotation failures" \
  --metric-name RotationFailed \
  --namespace AWS/SecretsManager \
  --statistic Sum \
  --period 300 \
  --evaluation-periods 1 \
  --threshold 1 \
  --comparison-operator GreaterThanThreshold \
  --alarm-actions arn:aws:sns:us-east-1:123456789012:alerts

Rotation Audit Script

#!/bin/bash
# audit-rotations.sh

echo "Secrets Rotation Audit"
echo "====================="

aws secretsmanager list-secrets --query 'SecretList[*].[Name,RotationEnabled,LastRotatedDate]' \
  --output text | \
while read name enabled last_rotated; do
  echo ""
  echo "Secret: $name"
  echo "  Rotation Enabled: $enabled"
  echo "  Last Rotated: $last_rotated"
  
  if [ "$enabled" = "True" ]; then
    # Check rotation schedule
    rules=$(aws secretsmanager describe-secret --secret-id "$name" \
      --query 'RotationRules.AutomaticallyAfterDays' --output text)
    echo "  Rotation Schedule: Every $rules days"
    
    # Calculate days since last rotation
    if [ "$last_rotated" != "None" ]; then
      days_ago=$(( ($(date +%s) - $(date -d "$last_rotated" +%s)) / 86400 ))
      echo "  Days Since Rotation: $days_ago"
      
      if [ $days_ago -gt $rules ]; then
        echo 
      
    
  

Application Integration

Python SDK

import boto3
import json

def get_secret(secret_name):
    """Retrieve secret from Secrets Manager"""
    client = boto3.client('secretsmanager')
    
    try:
        response = client.get_secret_value(SecretId=secret_name)
        return json.loads(response['SecretString'])
    except Exception as e:
        print(f"Error retrieving secret: {e}")
        raise

# Usage
db_creds = get_secret('prod/db/mysql')
connection = pymysql.connect(
    host=db_creds['host'],
    user=db_creds['username'],
    password=db_creds['password'],
    database=db_creds['dbname']
)

Node.js SDK

const AWS = require('aws-sdk');
const secretsManager = new AWS.SecretsManager();

async function getSecret(secretName) {
  try {
    const data = await secretsManager.getSecretValue({
      SecretId: secretName
    }).promise();
    
    return JSON.parse(data.SecretString);
  } catch (err) {
    console.error('Error retrieving secret:', err);
    throw err;
  }
}

// Usage
const dbCreds = await getSecret('prod/db/mysql');
const connection = mysql.createConnection({
  host: dbCreds.host,
  user: dbCreds.username,
  password: dbCreds.password,
  database: dbCreds.dbname
});

Rotation Best Practices

Planning

• Identify all secrets requiring rotation
• Define rotation schedules (30, 60, 90 days)
• Test rotation in non-production first
• Document rotation procedures
• Plan for emergency rotation

Implementation

• Use AWS managed rotation when possible
• Implement proper error handling
• Add CloudWatch monitoring
• Test application compatibility
• Implement gradual rollout

Operations

• Monitor rotation success/failure
• Set up alerts for failures
• Regular rotation audits
• Document troubleshooting steps
• Maintain rotation runbooks

Emergency Rotation

# Immediate rotation (compromise detected)
aws secretsmanager rotate-secret \
  --secret-id prod/db/mysql \
  --rotate-immediately

# Force rotation even if recently rotated
aws secretsmanager rotate-secret \
  --secret-id prod/api/stripe \
  --rotation-lambda-arn arn:aws:lambda:us-east-1:123456789012:function:RotateStripeKey \
  --rotate-immediately

# Verify rotation completed
aws secretsmanager describe-secret \
  --secret-id prod/db/mysql \
  --query 'LastRotatedDate'

Compliance Tracking

#!/usr/bin/env python3
# compliance-report.py

import boto3
from datetime import datetime, timedelta

client = boto3.client('secretsmanager')

def generate_compliance_report():
    secrets = client.list_secrets()['SecretList']
    
    compliant = []
    non_compliant = []
    
    for secret in secrets:
        name = secret['Name']
        rotation_enabled = secret.get('RotationEnabled', False)
        last_rotated = secret.get('LastRotatedDate')
        
        if not rotation_enabled:
            non_compliant.append({
                'name': name,
                'issue': 'Rotation not enabled'
            })
            continue
        
        if last_rotated:
            days_ago = (datetime.now(last_rotated.tzinfo) - last_rotated).days
            if days_ago > 90:
                non_compliant.append({
                    'name': name,
                    'issue': f'Not rotated in {days_ago} days'
                })
            else:
                compliant.append(name)
        else:
            non_compliant.append({
                'name': name,
                'issue': 'Never rotated'
            })
    
    print(f"Compliant Secrets: {len(compliant)}")
    print(f"Non-Compliant Secrets: {len(non_compliant)}")
    ()
     item  non_compliant:
        ()
