Use of Seccomp Profiles to secure container workloads

The aim of this task is to build an understanding of seccomp, and to use seccomp to secure containers.

Guidance

1. Prepare and read about seccomp so you get a feel for what seccomp is all about. You should then be able to talk about terms like syscalls, seccomp and seccomp profile.
2. Create an Exoscale Account and a VM (Linux Ubuntu 22.04 LTS 64-bit) and make sure you can SSH into it. If you have already received an invitation by e-mail for Exoscale, you can of course use this account.
3. Install docker on the vm.
4. Read the Story
5. Read Story 2 and help your colleague.

Additional task

• Maybe you can help Alice with her task.
• Maybe you can support Alice and Bob with their problem as well.
• Check out tracee from aquasecurity to trace syscalls.
• Check out how you could use seccomp to secure a Kubernetes Cluster
