Which options can limit access to a Samba share? (Select TWO correct answers)

The ability to limit access to a Samba share is a crucial aspect of managing file sharing securely in a network environment. One of the effective methods for controlling who can access a share is by specifying which users have permission to access it.

The options that limit access include the concept of "valid users." This directive in the Samba configuration file is used to specify which users are allowed to access the share. Only those users who are listed as 'valid' will be able to connect to the share, effectively restricting access to specified individuals.

Similarly, "valid groups" serves a similar purpose. It allows administrators to specify which groups of users can access the share. If a user belongs to one of these defined groups, they gain access; if not, they are denied entry. This method is beneficial in environments where user management is streamlined through group memberships, making it easier to manage permissions for multiple users at once.

Both "valid users" and "valid groups" directly impact access control, ensuring that only authorized personnel can view or interact with the data in the Samba share, enhancing the overall security of the system.
