Why it matters

Remote administration services such as RDP, VNC, Docker, Kubernetes, and management consoles are high-value targets. Public exposure allows anyone on the Internet to attempt passwords or exploit an unpatched service.

What to do

Remove direct Internet access and require a VPN, a hardened access gateway, or trusted source networks; also use MFA where supported.

Why it matters

Databases and caches often contain sensitive information and are normally used only by internal applications. Direct Internet access makes password attacks and configuration mistakes much more likely to become a data breach.

What to do

Listen only on private interfaces, allow connections only from required application systems, and require strong authentication and encryption.

Why it matters

Older services such as Telnet, FTP, and unencrypted mail or directory protocols can send passwords and data in readable form. Anyone able to observe the network path may capture them.

What to do

Disable the legacy service or replace it with an encrypted alternative such as SSH, SFTP, HTTPS, or the secure version of the mail protocol.
