HTTPS and SSH are considered secure access types of hosts in the cloud because they use encryption and authentication to protect the data and the identity of the users. HTTPS is a protocol that uses SSL or TLS to encrypt the communication between a web browser and a web server. SSH is a protocol that allows secure remote login and file transfer over a network. Both HTTPS and SSH prevent unauthorized access, eavesdropping, and tampering of the data in transit.
