Linux Runtime Security and Forensics using eBPF

Tracee: Runtime Security and Forensics using eBPF

Tracee is a Runtime Security and forensics tool for Linux. It is using Linux eBPF technology to trace your system and applications at runtime, and analyze collected events to detect suspicious behavioral patterns. It is delivered as a Docker image that monitors the OS and detects suspicious behavior based on a predefined set of behavioral patterns.

Quickstart

Before you proceed, make sure you follow the minimum requirements for running Tracee.

1. Running tracee:latest

   docker run \
     --name tracee --rm -it \
     --pid=host --cgroupns=host --privileged \
     -v /etc/os-release:/etc/os-release-host:ro \
     -e LIBBPFGO_OSRELEASE_FILE=/etc/os-release-host \
     aquasec/tracee:latest

2. Running tracee:full

   docker run --name tracee --rm -it \
     --pid=host --cgroupns=host --privileged \
     -v /etc/os-release:/etc/os-release-host:ro \
     -e LIBBPFGO_OSRELEASE_FILE=/etc/os-release-host \
     -v /usr/src:/usr/src:ro \
     -v /lib/modules:/lib/modules:ro \
     -v /tmp/tracee:/tmp/tracee:rw \
     aquasec/tracee:full

The default (latest) image is lightweight and portable. It is supposed to support different kernel versions without having to build source code. If the host kernel does not support BTF then you may use the full container image. The full container will compile an eBPF object during startup, if you do not have one already cached in /tmp/tracee.

You may need to change the volume mounts for the kernel headers based on your setup. See Linux Headers section for more info.

This will run Tracee with default settings and start reporting detections to standard output. In order to simulate a suspicious behavior, you can simply run:

strace ls

in another terminal. This will trigger the "Anti-Debugging" signature, which is loaded by default, and you will get a warning:

INFO: probing tracee-ebpf capabilities...
INFO: starting tracee-ebpf...
INFO: starting tracee-rules...

Trace

In some cases, you might want to leverage Tracee's eBPF event collection capabilities directly, without involving the detection engine. This might be useful for debugging/troubleshooting/analysis/research/education.

Just execute docker with trace argument first, and tracee-ebpf will be executed, instead of the full tracee detection engine.

docker run \
  --name tracee --rm -it \
  --pid=host --cgroupns=host --privileged \
  -v /etc/os-release:/etc/os-release-host:ro \
  -e LIBBPFGO_OSRELEASE_FILE=/etc/os-release-host \
  aquasec/tracee:latest \
  trace

See documentation or add the --help flag for more.

Components

Tracee is composed of the following sub-projects, which are hosted in the aquasecurity/tracee repository:

• Tracee-eBPF - Linux Tracing and Forensics using eBPF
• Tracee-Rules - Runtime Security Detection Engine
