AWS Secrets Manager is a secrets management service that helps you protect access to your applications, services, and IT resources. It eliminates the up-front investment and ongoing maintenance costs of operating your own infrastructure, which are traditionally required to maintain secrets such as database credentials, on-premises resource credentials, SaaS application credentials, third-party API keys, and Secure Shell (SSH) keys.
For example, AWS Secrets Manager supports the secure rotation of secrets without the risk of impacting applications. By using AWS Secrets Manager, you can replace secrets in your applications and scripts programmatically, which delivers a more streamlined and efficient process. It eliminates the need for manual intervention, increasing the overall security of your system.
import boto3
import base64
from botocore.exceptions import BotoCoreError, ClientError
def get_secret():
secret_name = "MySecretName"
region_name = "us-west-2"
session = boto3.session.Session(region_name=region_name)
client = session.client(service_name='secretsmanager')
get_secret_value_response = client.get_secret_value(SecretId=secret_name)
if 'SecretString' in get_secret_value_response:
return get_secret_value_response['SecretString']
else:
return base64.b64decode(get_secret_value_response['SecretBinary'])
The example above shows how to retrieve a secret value using the AWS SDK for Python (Boto3).
AWS Systems Manager Parameter Store
AWS Systems Manager Parameter Store provides secure, hierarchical storage for configuration data and secrets management. It allows you to store values such as passwords, database strings, and license codes as parameter values. You can store values as plain text or encrypted data.
The Parameter Store is tightly integrated with AWS Identity and Access Management (IAM), allowing granular access permissions for any level in the parameter hierarchy. Similarly, you can use AWS CloudTrail for auditing parameter use.
import boto3
def get_parameter():
ssm = boto3.client('ssm', region_name='us-west-2')
parameter = ssm.get_parameter(Name='/MyParameter', WithDecryption=True)
return parameter['Parameter']['Value']
In this sample Python code snippet, we’re using Boto3 to get a parameter value from the AWS Systems Manager Parameter Store.
Comparison: AWS Secrets Manager vs. Systems Manager Parameter Store
Different businesses have different requirements, so choosing between AWS Secrets Manager and Systems Manager Parameter Store greatly depends on your specific needs. Here is a comparative analysis of both services:
