External Scan - An external vulnerability scan is a scan that is conducted from outside of the network. These scans target WAN IP addresses, scanning perimeter defences like websites, web applications, and network firewalls for weaknesses. CyberCNS provides external scans with configurable profiles so that you have control over the depth of the scan that needs to be performed.
In order for the external scan to work the IP and hostname will be scanned from the following IP Addresses based on the region. Your region is the suffix on your portal URL. E.g. If your URL is portaluseast2.mycybercns.com then your region is useast2. The IPs are as listed below.
Region | Originating IP Address for External Scan |
|---|---|
USWEST2 | 44.231.123.15 |
EUCENTRAL1 | 35.158.55.215 |
EUWEST2 | 13.41.172.255 |
APSOUTHEAST2 | 54.206.202.191 |
USEAST2 | 3.22.165.174 |
