- Avoid configuring DDVE with a public IP address to avoid brute force attacks on the DDVE.
- For better security, it is recommended to disable username and password-based user authentication. If username and password-based authentication is required, configure it with a strong password.
- After protecting the DDVE using secure setup, network traffic that enters DDVE can be filtered within DDVE by using the iptables feature.
- Because the DDVE instance on Google Cloud is always running in a VPC, configure the VPC so that only required and trusted clients have access to the DD system.
