Catbird’s Intelligent Vulnerability Monitor is unique in scanning for vulnerabilities introduced within the customer’s own network, as well as those originating from the public Internet. Catbird scans both the public Internet-facing ports (External Scan) as well as the private ports that are exposed only in the customer’s own LAN (Internal Scan).
In addition, for efficiency and ultimate security, Catbird also provides two kinds of scanning of external ports: a Complete Scan or a Range Scan. A Complete Scan will scan all 65K ports and is typically used for IP addresses which are in use and which face the public Internet. A Range Scan will scan only the “well-known” ports (i.e., port 80 for http traffic, port 25 for mail traffic, or whatever an administrator designates). A Range Scan would typically be used to check unused IP addresses allocated to a customer to make sure they are not being exploited.
