Discussion

Guest access to shares permits anonymous access and is not permitted.

Check Content

Check the encryption setting for the Samba configuration. Default locations for this file include /etc, /etc/sfw, /etc/samba, and /etc/sfw/samba. If the system has Samba installed in non-standard locations, also check the smb.conf in those locations. Procedure: # grep -i 'guest ok' /etc/smb.conf /etc/sfw/smb.conf /etc/samba/smb.conf /etc/sfw/samba/smb.conf If the setting exists and is set to yes, this is a finding.

Fix Text

Edit the smb.conf file and change the guest ok setting to no.
