When a newer sensor version is available than the one deployed, you’ll see “Update Available” next to the sensor name. You should update the sensor to the newer version to take advantage of new features, bug fixes and to remediate vulnerabilities.
Sensors deployed on docker with the installsensor.sh script or docker run command will be updated automatically (unless the --disable-auto-update option was used for the install script). Sensors are not updated automatically for Kubernetes deployments. Refer to “Update the sensor deployed in Kubernetes” in the Qualys Container Security Sensor Deployment Guide for instructions.
The Qualys Container Sensor image hosted on Docker Hub does not support auto update. See “Upgrading the sensor” in the section “Installing the sensor from Docker Hub” in the Qualys Container Security Sensor Deployment Guide for instructions.
