encrypt-in-transit-data

Default Severity: high

Explanation

In-transit data should be encrypted so that if traffic is intercepted data will not be exposed in plaintext to attackers.

Possible Impact

Intercepted data can be read in transit

Suggested Resolution

Enforce SSL for all connections

Insecure Example

The following example will fail the google-sql-encrypt-in-transit-data check. 

 resource "google_sql_database_instance" "postgres" {
    name             = "postgres-instance-a"
    database_version = "POSTGRES_11"

    settings {
        tier = "db-f1-micro"

        ip_configuration {
            ipv4_enabled = false
            authorized_networks {
                value           = "108.12.12.0/24"
                name            = "internal"
            }
            require_ssl = false
        }
    }
 }

Secure Example

The following example will pass the google-sql-encrypt-in-transit-data check. 

 resource "google_sql_database_instance" "postgres" {
    name             = "postgres-instance-a"
    database_version = "POSTGRES_11"

    settings {
        tier = "db-f1-micro"

        ip_configuration {
            ipv4_enabled = false
            authorized_networks {
                value           = "108.12.12.0/24"
                name            = "internal"
            }
            require_ssl = true
        }
    }
 }
