Virtual network based firewall rules are used to enable traffic from a specific subnet to Azure Database for MySQL while ensuring the traffic stays within the Azure boundary. This policy provides a way to audit if the Azure Database for MySQL has virtual network service endpoint being used.
Ensure security controls for remote access to server include the following:
(a) restrict access to only hardened and locked down end-point devices;
(b) use secure tunnels such as TLS and VPN IPSec;
(c) deploy ‘gateway’ server with adequate perimeter defences and protection such as firewall, IPS and antivirus; and
(d) close relevant ports immediately upon expiry of remote access.
