I have a small Raspberry Pi here that is supposed to run 24/7 as a small server with a DMS installed. Since the DMS also contains sensitive data, I want to protect it as much as possible.
I did a local port scan and apparently only the ports that the DMS needs for the web frontend and the SMB share are open. A port scan from outside showed no open ports at all.
I would appreciate any tips on how to make this little thing even more secure. Thank you!
