Overcoming Barriers to Vulnerability Scanning

Vulnerability scanning is often a high priority for cybersecurity professionals, but other technologists in the organization may not see it as an important activity. Cybersecurity analysts should be aware of the barriers raised by others to vulnerability scanning and ways to address those concerns. Some common barriers to overcome include the following:

Service Degradations The most common barrier to vulnerability scanning raised by technology professionals. Vulnerability scans consume network bandwidth and tie up the resources on systems that are the targets of scans. This may degrade system functionality and poses a risk of interrupting business processes. Cybersecurity professionals may address these concerns by tuning scans to consume less bandwidth and coordinating scan times with operational schedules. Figure 3.16 shows ways that administrators may adjust scan intensity in QualysGuard.
