 #### Policy
 
+- FIX: Updated Deny-MgmtPorts-From-Internet Policy Definition to deny the use of "0.0.0.0/0" as a Source Address Prefix in Network Security Rules. "0.0.0.0/0" is equivalent to "Internet" or "*", and therefore should be denied.
 - FIX: Updated the Audit-Tags-Mandatory-RG Policy Defintion to mode 'All' from 'Indexed' so that it evaluates resource group tags as intended.
