Sensitive-path guards
Finder blocks reading well-known secret files even though it can otherwise browse the whole filesystem.
What's blocked
~/.sshand private keys~/.aws/credentials*.pem/*.keyand similar key material
Attempts to list, read, download, or view these return "Restricted due to security reasons" and are written to the audit log.
Important
NuxPanel is a powerful admin surface. Restrict network access to it (security group / firewall to your own IP, or an SSH tunnel) and use a strong admin password.
