Automated Cloud-Native Incident Response with Kubernetes and Service Mesh
20 April 2023 | KubeCon, Amsterdam Netherlands
Security incident response is a well-understood operation, with established best practices like the MITRE Att&ck Framework and the Lockheed Martin Kill Chain.
Tooling to aid and automate incident response exists, but not all of it is applicable to cloud-native platforms. For example, playbook apps are generally applicable, but the steps to move compromised workloads to an isolated forensics network are platform-specific, and new implementations are needed for the cloud-native world.
In this talk, Matt and Francesco will
- Recap incident response 101
- Introduce some cloud-native tech including Kubernetes, Istio, and GitOps
- Show an Operator built by Matt for dynamically adding complex layer-7 traffic rules in response to changes in the environment, which will be used as part of the demo
- Walk you through a response to a log4shell attack against a workload in a k8s cluster: sensor alert, SIEM analysis, IRP automation (honeypots, isolation), building the IoC, and killing the attack.
