Scan Infrastructure for Runtime Misconfigurations
Description
Cloud misconfigurations occur when resources have not been constructed properly, leaving your systems vulnerable to attack. Cloud environment misconfigurations can cause system outages, unwanted downtime, or security risks. Causes can include overly complex environments, insufficient security practice knowledge, and human error due to manual processes.
