%description
Cilium’s new Tetragon component enables powerful real-time, eBPF-based Security
Observability and Runtime Enforcement.

Tetragon detects and is able to react to security-significant events, such as

* Process execution events
* System call activity
* I/O activity including network & file access

When used in a Kubernetes environment, Tetragon is Kubernetes-aware - that is,
it understands Kubernetes identities such as namespaces, pods and so on - so
that security event detection can be configured in relation to individual
workloads.
