Hello Experts, i recently purchased a used server for building a home lab environment. i would like to install win 7 professional as the servers main OS, then install vmware workstation for my virtual machines for sharepoint, exchange, AD practice. I know i can set up remote access to this server by allowing rdp access from my home router (configuring port forwarding), then rdp from public internet using my home servers public IP. I've already tried this and the server was infected with ransomware. Can anybody tell me how i can make this as secure as possible while on a budget?
