What user permissions can I set on my Synology NAS?

Synology Network Attached Storage provides a comprehensive set of user permissions to ensure that data is secure while allowing appropriate access levels for users. The permission settings can be configured on multiple levels, including shared folders, shared applications, and specific services. Users can be assigned roles such as administrator or standard user, which dictate their level of control over the system. Administrators have full access to all settings and data, while standard users can have limitations placed on their access depending on the requirement. For shared folders, permissions can include read, write, and no access. This allows for granular control over who can view or modify content. Synology devices also support group permissions, enabling multiple users to share the same access rights without configuring each user individually. Moreover, there are also application-level permissions, which can restrict or grant access to specific apps such as Surveillance Station, Cloud Sync, and others. Users can also be allowed or denied access to network services like FTP, SMB, and WebDAV. For detailed guidance on setting these permissions, it may be helpful to check the current Synology documentation available on their web page.
