The final solution must scale with grow- ing business demands for security assessments so automation of distributed scanners was a primary consideration. Additionally, the scanners must be cost-effective to deploy, easy to manage more on this later , and enable centralized reporting. Figure 1.

Multiple targets would be useful when it is desirable to customize the level of scanning based on different device types. Scan Configs — preset vulnerability scan con- figurations using different levels of scanning tech- niques. As the more intrusive configs can bring down hosts, use caution when making decisions on how and when to run the scans. For this exercise, I set up three separate scan targets — our workstation network, our server net- work, and one for my work computer. For each of these I used the Full and Fast scan option.
