Hello all, recently subscribed to get the ISPConfig book, it's quite nice but I got it because I wanted to read the security considerations. I'll be running a few e-commerce websites so I'd like to get a nice security for it. I'm already using ufw, let's encrypt for SSL on whole server (config panel, mail, ftp...), give the clients secure passwords and so. Any tips on adding more security? Btw, I'm currently using Apache but probably will move onto nginx, I've got more personal experience with nginx, does ISPConfig work equally with them, or does it support more features on Apache? Thanks.
