Risk-based triage has transformed container security and now prioritizes high-impact threats

The best features Qualys TotalCloud offers currently include managing cloud infrastructure and container security while facing major challenges such as alert fatigue. Traditional vulnerability scanners flag hundreds of CVEs on short-lived Kubernetes containers, some of which have no internet exposure or are gone before we can even triage them. I leverage Qualys TotalCloud to move beyond static CVSS. I use it to implement runtime exposure, correlation risk reprioritization, and shift-left integration. This notifies developers to fix a base image upstream rather than patching live ephemeral instances. In my work with cloud and container security, the biggest operational hurdle was alert fatigue. I use Qualys to shift left from static CVSS severity to context-aware risk prioritization. I correlated raw vulnerability data with real-time risk factors such as public network exposure, active runtime execution, or overly permissive IAM roles. This allows us to immediately drop the priority of isolated containers and escalate lower-severity CVEs that sit on an exposed, high-risk path. We can map these findings directly back to our CI/CD pipelines so developers can patch the root base images upstream. We have drastically cut down the signal-to-noise ratio, saved a lot of manual hours doing triage work, and ensured engineering effort goes directly towards high-impact risk reduction.

Offers easy management and container connection with HTTPS, but the support needs to improve

I have experience with the solution's setup in Rio de Janeiro, Brazil and our company has assisted in the development of a cluster in a research department, but we didn't start from scratch because we have IT professionals who have installed Kubernetes across 12 nodes of a cluster and a new environment can be created for a new platform. I also had another setup experience of Red Hat Advanced Cluster Security for Kubernetes in Portugal where I had to implement the solution in a cluster of 22 computer servers, which was completed with assistance from the IT department of the company. The initial setup process of the solution can be considered as difficult. The setup process involves using the permissions, subnets and range of IPs, which makes it complex. Deploying Red Hat Advanced Cluster Security for Kubernetes takes around eight to ten hours for new clusters. The solution's deployment can be divided into three parts. The first part involves OpenStack, where the cluster's resources need to be identified. The second part involves virtualizing assets and identifying other physical assets, for which OpenStack, Kubernetes, or OpenShift are used. The third part of the deployment involves dividing the networks into subnetworks and implementing automation to deploy the microservices using Helm. The number of professionals required for the solution's deployment depends upon the presence of automated scripts. Ideally, two or three professionals are required to set up Red Hat Advanced Cluster Security for Kubernetes.

Has significantly improved proactive monitoring through automated asset discovery and seamless integration with cloud environments

Making the system smarter would be beneficial. Adding modules for integration with AWS and Azure would be helpful. Adding capabilities for the scanner to automatically pick up changes and add assets automatically would be valuable. When discussing a big company, it is mandatory to have tools that will assist us rather than waiting for manual input to add hosts. Adding assets manually is prone to mistakes. Humans might forget to add an asset or make errors when adding multiple assets. Taking the human element out of the context and making it more streamlined is the future for security. The human should be involved where expertise is needed, such as analysis and decision-making. Currently, with resource constraints, we need tools to collect and aggregate data, eliminate false positives as much as possible, and present relevant information to employees for action.
