Renaud Deraison, Jack Daniel, and I presented the last webcast in the "Vulnerabilities Exposed" series - "Communicating Vulnerabilities to Management: Making the Rubber Meet the Road." View the webcast recording and responses to questions asked during the session.

Active scanning, for the most part, is a snapshot-in-time view of vulnerabilities that exist in an organization’s environment. In a typical organization, scans occur on a quarterly or even monthly basis. However, the scans only tell you what happened in that moment, not what happened in the intervening days between scans. By scanning more frequently (and introducing real-time, passive scanning), organizations will have more accurate metrics that show how long an detected vulnerability was present and when it was mitigated.

Tenable has added new Nessus malware detection features to further detect known and unknown Windows processes based on their reputation. This new ability to detect unknown software helps find new types of malware, as well as new types of software that are potentially unwanted or unmanaged within a network.
