As a hacker, you are used to spinning up Digital Ocean droplets, running a bare metal server at OVHCloud or experimenting with a Raspberry Pi.
Access to systems should be protected with at least two factor authentication (2FA), based on something you know (like a passphrase) and something you have (like a certificate on your laptop). The most common tool used to remotely administer a Linux server is SSH. It is by default installed on Linux workstations or servers, and recent versions of Windows include it as an optional component.
