Looking to see if BigFix has a signature date field that indicates when the vulnerability database was last updated. Is there such a field?
Are you referring to the vulnerability information on BigFix Inventory?
Both in BigFix Inventory and the Vulnerability site in Compliance. Do you know if either has a field that indicates the date of the database?
For BigFix Inventory it is updated with the catalog import. A catalog containing updated signatures is released approximately once a month. You are free to import it at other intervals manually.
For BigFix Compliance you should do it as mentioned in the documentation.
Hope this answers your query.
