Unified Manager checks for a new Active IQ rules file automatically and downloads a new file when there are newer rules. However, in sites with no external network access, you need to upload the rules file manually.
It is recommended that you download a new rules file approximately once a month to make sure your storage systems are being protected and that they are running optimally. The rules file is located at: http://mysupport.netapp.com/NOW/public/unified_manager/bin/secure_rules.zip
