This framework can generate Seccomp profiles for Docker images to harden container and reduce the Linux kernel attack surface available to the container. The general goal is to remove functionalities not required by containers by performing static analysis.

We experienced event-loss issues in the dynamic analysis phase of Confine. As a result we have added support for other tools as well. Currently we support Sysdig and execsnoop. We have also added a tool to only test the monitoring phase of Confine. It launches the monitoring tool and a requested container, extracts the list of binaries and reports the number. We expect this number to be same in the same environment. It can be run multiple times to show whether or not events are being dropped.
sudo python3.8 dynAnalysisStressTest.py --imagename nginx --monitoringtool [sysdig/execsnoop] --count 100
NOTE: There seems to be an event-loss issue in the older versions of Sysdig. We recommend using the latest version (>0.26)
