• Group permissions: Group permissions can be used to restrict access to specific commands and files to members of a specific group. For example, a group of administrators may be granted permission to modify critical system files.
• Host-based access control: Host-based access control can be used to restrict access to an SSH server to specific hosts. For example, an SSH server may be configured to only allow access from hosts within a specific IP address range.
• Certificate-based access control: Certificate-based access control can be used to restrict access to an SSH server to users who have a valid digital certificate. For example, an SSH server may be configured to only allow access from users who have a certificate issued by a specific certificate authority.

Access control is an important component of SSH IoT devices examples because it helps to protect against unauthorized access and data breaches. By restricting access to only authorized users, SSH helps to ensure that IoT devices are secure and that data is protected from unauthorized access.
