Connection security review

There is not such Matrix available in the UI.
You can use the Dataiku API to build something similar , not you would need to run this with Admin user:

import dataiku
import pandas as pd

# Get a list of connections
client = dataiku.api_client()
dss_connections = client.list_connections()

# Initialize lists to store the values
connection_list = []
allowed_groups_list = []

# Iterate over the connections and extract the relevant values
for connection in dss_connections:
    conn = client.get_connection(connection).get_definition()
    if conn['usableBy'] == 'ALLOWED':
        allowed_groups = conn['allowedGroups']
    else:
        allowed_groups = ["ALL"]
    connection_list.append(connection)
    allowed_groups_list.append(allowed_groups)

# Create a dataframe with the extracted values
df_connection = pd.DataFrame({
    'connection': connection_list,
    'allowed_groups': allowed_groups_list
})

# Explode the 'allowed_groups' column
df_connection = df_connection.explode('allowed_groups').reset_index(drop=True)
df_connection
