The query searches for event 5143, which is triggered when a share is created or changed and includes de share permissions. First it checks to see if this is a whitelisted share for the system (e.g. domaincontroller netlogon, printserver print$ etc.). The share permissions are then checked against 'allow' rule (A) for a number of well known overly permissive groups, like all users, guests, authenticated users etc. If these are found, an alert is raised so the share creation may be audited. Note: this rule only checks for changed permissions, to prevent repeat alerts if for example a comment is changed, but the permissions are not altered.
