Sql log connections flag remediation

Using Console

Using CLI

To remediate the PostgreSQL Log Connections Flag Should Be On misconfiguration for GCP using GCP CLI, follow these steps:

Open the Cloud Shell in the GCP Console.
Run the following command to list the available PostgreSQL instances in your project:
```
gcloud sql instances list
```
Note down the instance name of the PostgreSQL instance you want to remediate.
Run the following command to enable the log_connections flag for the PostgreSQL instance:
```
gcloud sql instances patch [INSTANCE_NAME] --database-flags log_connections=on
```
Replace [INSTANCE_NAME] with the name of your PostgreSQL instance.
Confirm that the log_connections flag has been enabled by running the following command:
```
gcloud sql instances describe [INSTANCE_NAME] | grep log_connections
```
Replace [INSTANCE_NAME] with the name of your PostgreSQL instance. The output should show that the log_connections flag is set to “on”.
```
log_connections: on
```
Your PostgreSQL instance is now remediated with the log_connections flag enabled.

Using Python

To remediate the PostgreSQL log connections flag misconfiguration in GCP using Python, follow these steps:

Install the google-cloud-secret-manager and google-auth Python libraries using pip:
```
pip install google-cloud-secret-manager google-auth
```

Import the necessary libraries and authenticate to the GCP project:

from google.cloud import secretmanager
from google.oauth2 import service_account

credentials = service_account.Credentials.from_service_account_file('/path/to/key.json')
client = secretmanager.SecretManagerServiceClient(credentials=credentials)

Replace /path/to/key.json with the path to your GCP service account key file.

Retrieve the value of the postgres-config secret:

secret_name = "postgres-config"
project_id = "my-project-id"
version = "latest"

name = f"projects/{project_id}/secrets/{secret_name}/versions/{version}"
response = client.access_secret_version(request={"name": name})
config = response.payload.data.decode("UTF-8")

Update the postgresql.conf file to enable logging of connections:

config_lines = config.split("\n")
new_config_lines = []

for line in config_lines:
    if line.startswith("#log_connections = off"):
        new_config_lines.append("log_connections = on")
    else:
        new_config_lines.append(line)

new_config = "\n".join(new_config_lines)

Write the updated configuration back to the secret:

parent = f"projects/{project_id}"
payload = {"data": new_config.encode("UTF-8")}
response = client.update_secret(request={"secret": {"name": secret_name, "payload": payload}, "update_mask": {"paths": ["payload"]}, "parent": parent})

This will update the postgres-config secret with the new configuration that enables logging of connections.

Verify that the configuration was updated successfully by checking the postgresql.conf file on the PostgreSQL server.

# Connect to the PostgreSQL server
psql -h <hostname> -U <username> -d <database>

# Check the value of the log_connections parameter
SHOW log_connections;

The output should be on.
