How it works

To be able to detect vulnerabilities, now agents are able to natively collect a list of installed applications, sending it periodically to the manager (where it is stored in local sqlite databases, one per agent). Also, the manager builds a global vulnerability database, from publicly available CVE repositories, using it later to cross-correlate this information with the agent’s applications inventory data.

The global vulnerability database is created automatically, currently pulling data from the following repositories:

This database can be configured to be updated periodically, ensuring that the solution will check for the very latest CVEs.

Once the global vulnerability database (with the CVEs) is created, the detection process looks for vulnerable packages in the inventory databases (unique per agent). Alerts are generated when a CVE (Common Vulnerabilities and Exposures) affects a package that is known to be installed in one of the monitored servers. A package is labeled as vulnerable when its version is contained within the affected range of a CVE.
