I have created certificate with following definition. The certificate is created .Is there any option to retrieve certificate definition from system objects ?If we can retrieve definition ,what is the best way to restrict user to view create certificate definition?
I checked sys.sql_modules table but couldn't find anything
CREATE CERTIFICATE xxxx_Certificate ENCRYPTION BY PASSWORD = 'pGFD4bb925DGvbd2439587y' WITH SUBJECT = 'YYYY Information', EXPIRY_DATE = '20221231';

As per my knowledge there is no proper way retrieve Azure key vault secret using T-SQL.
We can retrieve key vault secret using Py spark code in Synapse pool.
I created Azure key vault and created secret.
Image for reference:
value of secret:
I created synapse analytics and opened synapse studio and created notebook as mentioned below
I executed below code to retrieve the value of secret.
from notebookutils import mssparkutils
mssparkutils.credentials.getSecret('<keyvault_name>' , '<secret_name>')
I got the azure key vault value.
you can follow this way to retrieve secret value from Azure key vault.

1/ Everyday at 3am, we are runnning a script alfa.sh on server A in order to send some backups to AWS (s3 bucket).
As a requirement we had to configure AWS (aws configure) on the server which means the Secret Key and Access Key are stored on this server. We now would like to use short TTL credential valid only from 3am to 3:15am . Vault Hashicorp does that very well
2/ On server B we have a Vault Hashicorp installed and we managed to generate short ttl dynamic secrets for our s3 bucket (access key / secret key).
3/We now would like to pass the the daily generated dynamic secrets to our alpha.sh. Any idea how to achieve this?
4/Since we are generating a new Secret Key and Access Key, I understand that a new AWS configuration "aws configure" will have to be performed on server A in order to be able to perform the backup. Any experience with this?
DISCLAIMER: I have no experience with aws configure so someone else may have to answer this part of the question. But I believe it's not super relevant to the problem here, so I'll give my partial answer.
First things first - solve your "secret zero" problem. If you are using the AWS secrets engine, it seems unlikely that your server is running on AWS, as you could skip the middle man and just give your server an IAM policy that allowed direct access to the S3 resource. So find the best Vault auth method for your use case. If your server is in a cloud like AWS, Azure, GCP, etc or container like K8S, CF provider, or has a JWT token delivered along with a JWKS endpoint Vault can trust, target one of those, and if all else fails, use AppRole authentication delivering a wrapped token via a trusted CI solution.
Then, log into Vault in your shell script using those credentials. The login will look different depending on the auth method chosen. You can also leverage Vault Agent to automatically handle the login for you, and cache secrets locally.
#!/usr/bin/env bash
## Dynamic Login
vault login -method="${DYNAMIC_AUTH_METHOD}" role=my-role
## OR AppRole Login
resp=$(vault write -format=json auth/approle/login role-id="${ROLE_ID}" secret-id="${SECRET_ID}")
VAULT_TOKEN=$(echo "${resp}" | jq -r .auth.client_token)
export VAULT_TOKEN
Then, pull down the AWS dynamic secret. Each time you read a creds endpoint you will get a new credential pair, so it is important not to make multiple API calls here, and instead cache the entire API response, then parse the response for each necessary field.
#!/usr/bin/env bash
resp=$(vault read -format=json aws/creds/my-role)
AWS_ACCESS_KEY_ID=$(echo "${resp}" | jq -r .data.access_key)
export AWS_ACCESS_KEY_ID
AWS_SECRET_KEY_ID=$(echo "${resp}" | jq -r .data.secret_key)
export AWS_SECRET_KEY_ID
This is a very general answer establishing a pattern. Your environment particulars will determine manner of execution. You can improve this pattern by leveraging features like CIDR binds, number of uses of auth credentials, token wrapping, and delivery via CI solution.
How to get the secrets from AKV using Azure SQL Query or any other methods to make a connection string for SSIS?
Enable Managed Identity on your Azure SQL DB.
Make an HTTP request to the MSI endpoint to get an access token for Key Vault.
Using the access token, make another HTTP call to the Key Vault for the secret you want.
I have an ASP.NET Core website that is used to store and retrieve encryption keys which are, at times, used to "sign transactions" on behalf of the user.
Since I'm in Azure, research indicates the most secure way to store these keys is via Azure Key Vault.
I've looked at this article, which shows that to gain access Azure Key Vault values, I would end up using credentials stored in the Web App's Application Configuration settings.
// Connect to Azure Key Vault using the Client Id and Client Secret (AAD) - Get them from Azure AD Application.
var keyVaultEndpoint = settings["AzureKeyVault:Endpoint"];
var keyVaultClientId = settings["AzureKeyVault:ClientId"];
var keyVaultClientSecret = settings["AzureKeyVault:ClientSecret"];
if (!string.IsNullOrEmpty(keyVaultEndpoint) && !string.IsNullOrEmpty(keyVaultClientId) && !string.IsNullOrEmpty(keyVaultClientSecret))
{
config.AddAzureKeyVault(keyVaultEndpoint, keyVaultClientId, keyVaultClientSecret, new DefaultKeyVaultSecretManager());
}
Web App Application Configuration settings are encrypted at rest and during transit, but their values can be leaked in a number of ways, hence the need for Key Vault.
My question, however, is if I have to store the Key Vault access credentials somewhere in the app configuration, doesn't that essentially limit the security of key vault values to the same level as what the configuration setting already provides? Does the extra level of indirection make a difference somehow?
What's the point of using Key Vault if someone can just access the Key Vault by reading the Key Vault credentials from the Web Config Settings?
What am I missing?
How can I connect to SQL database hosted on Microsoft Azure without having credentials in plain text in my .asp files or config files in VBScript?
I want to have the database connection string stored in Azure Key Vault, and have the web app access the key vault to get the connection string and then connect to the database.
I have looked at a lot of Microsoft documentations but they are all in C#. My web app is all in VBScript and .asp files and I don't want to spend the time rebuilding the whole web app to ASP.NET/.aspx
Thank you
You don't need Azure Key Vault in this case.
What you can do is to create a new App Setting in App Settings of Azure Web App, and make its value to be the connection string of your database. This will create an environment variable and you can access it with VBScript. This post shows how to access an environment variable with VBScript.
I found a way!
If I want to use the environment variables set under App Settings:
Set objWSH = CreateObject("WScript.Shell")
Set objUserVariables = objWSH.Environment("Process")
Response.Write(objUserVariables("APPSETTING_testAppSet"))
the prefix APPSETTING_ will be different if the variable is stored under Connection String
One other way I was able to use is to store the DB connection string in the Azure Key Vault. And then use OAuth access token to access Azure Key Vault. In this method, you have to send a POST request to Azure with ClientID and ClientSecret in the request body, then you will get an access token from the HTTP response. After that, send a GET request to the Key Vault endpoint with the access token in the request header. Then you will get the value of the key vault secret from the HTTP response.
Another way to do it is to use the MSI_ENDPOINT and MSI_SECRET and send the HTTP request to get the access token. And with that access token, you can access a key vault secret as well (you have to make sure that the Key Vault Access Policy is setup correctly).
I am trying to migrate an existing application that was using IAM permissions to write to a S3 bucket from EC2. According to Google documentation, you have a way to keep the same code and take advantage of the compatibility of GCS apis with S3. However, using the same code (I am just overriding the endpoint to use storage.googleapis.com instead), I hit the following exception:
com.amazonaws.SdkClientException: The requested metadata is not found at http://169.254.169.254/latest/meta-data/iam/security-credentials/
at com.amazonaws.internal.EC2CredentialsUtils.readResource(EC2CredentialsUtils.java:115)
at com.amazonaws.internal.EC2CredentialsUtils.readResource(EC2CredentialsUtils.java:77)

Is there a way to do that without having to pass an access key and a secret key to my app?
If you want to keep using your existing API, the only way is by using a Google developer key, a simple migration always requires these two steps:
Change the request endpoint to to the Cloud Storage request endpoint: As you mentioned, you already completed this step by overriding to the Cloud Storage request endpoint:
https://storage.googleapis.com/[BUCKET_NAME]/[OBJECT_NAME]
Replace the AWS access and secret Key with your Google developer key:
Because you are no longer going to be able to keep using the same IAM permissions you have previously set on AWS, authorization must be done using and access key and and a secret key, you will need to include an Authorization request header using your Google access key and create a signature using your Google secret key:
Authorization: AWS GOOG-ACCESS-KEY:signature
