Understanding the Datalake
...
The Armor data lake is a centralized repository for storing Armor collected data. With regards to vulnerabilities, the data lake contains all the data for every report created for an environment and all the historical data from when the reports are run. This can be a lot of data so narrowing down the scope of information is critical to making sense of it all.

Custom Fields:
vulnerability.published - the date an entry for the vulnerability was given a CVE
vulnerability.results - the criteria used to determine the presence of the vulnerability
vulnerability.cve - contains a link to the vulnerability's entry in the CVE database
vulnerability.solution - provides instructions, if any exist, for remediating the vulnerability
vulnerability.status - lists New if it is the first time a vulnerability is detected by a scan; Active if the vulnerability was been detected by two or more scans; Fixed if the vulnerability was detected in the previous scan but the most recent scan shows it as fixed; and Re-Opened if the vulnerability was verified fixed previously but is no longer so
vulnerability.first_found - the date of the first scan in which the vulnerability was detected for a given server
vulnerability.last_found - the date of the most recent scan in which the vulnerability was detected for a given server
vulnerability.discovery - indicates whether the vulnerability was discovered through remote and/or authenticated scanning
vulnerability.pci_flag - a flag that indicates whether the vulnerability must be fixed to pass PCI compliance
vulnerability.patchable - contains a 1 if the vulnerability can be patched and a 0 if no patches currently exist for it
vulnerability.last_modification - the date of the vulnerability attributes' (title, severity level, patch availability, CVSS scores, PCI relevance, etc.) last modification
vulnerability.diagnosis - gives information about the technical details of the vulnerability, affected packages, severity scoring, and detection
vulnerability.vulnerability_type - indicates whether the detection was a potential vulnerability (vulnerabilities that cannot be fully verified but have at least one necessary condition for the vulnerability) or a vulnerability (the vulnerability can be fully verified)
vulnerability.consequences - provides information about the access an attacker who successfully exploits the vulnerability might gain
