Solution is acting as a gateway for remote administration tasks. Available on HTTPS only. Allow RDP, VNC and SSH from it to our applicative end servers. Access is restrained to Admin with 2FA.
Pros
All port closed except 443
Attackable scope is limited
Administration tasks are under one entry point
Need
Privileged users accesses should only be made through a secure portal no matter is the end-devices.
All desks linked to network. Reliable Wifi installation. New Visio system. New Access card system. No services downtime. On-site servers physically moved. Recycling old hardware.
I wanted to host and tests some apps before publishing/use it on internet. The physical server hosting are light, small and silent. The solution must not consume a lot of ressources.
