Mesh-Kridik : An Open-Source Security Checker That Performs Security Checks On A Kubernetes Cluster

Mesh-Kridik is an open-source security checker that performs various security checks on a Kubernetes cluster with istio service mesh and outputs a security report

The security checks tests are the full implementation of istio security best practices

The security checks performed on a Kubernetes cluster with istio service mesh and is leveraged by OPA (Open Policy Agent) to enforce security rules, and the output audit report includes: the root cause of the security issue and proposed remediation for the security issue.

Requirements

* Go 1.16+
* jq
* istio Installation

git clone https://github.com/chen-keinan/mesh-kridik
cd mesh-kridik
make build

* ote: mesh-kridik require root user to be executed Quick Start

Execute Mesh-Kridik without any flags , execute all tests

./mesh-kridik

Execute mesh-kridik with flags , execute test on demand

Usage: mesh-kridik [–version] [–help] []
Available commands are:
-r , –report : run security checks and generate remediation report
-i , –include: execute only specific security check, example -i=1.1
-e , –exclude: ignore specific security check, example -e=1.1,2.0

Execute tests and generate failure tests report and it remediation’s

./mesh-kridik -r

for user plugins Example :

* MeshSecurityCheckResultHook – this hook accepts k8s service mesh security checks results Compile user plugin

go build -buildmode=plugin -o=~//.so ~//.go

Copy plugin to folder (.kube-kridik folder is created on the 1st startup)

cp ~//.so ~/.kube-kridik/plugins/compile/.so Download

Chain-Reactor - An Open Source Framework For Composing Executables That Simulate Adversary Behaviors And Techniques On Linux Endpoints

Chain Reactor is an open-source tool for testing detection and response coverage on Linux machines. The tool generates executables that simulate sequences of actions like process creation and network connection. Chain Reactor assumes no prior engineering experience; the tool consumes JSON, so customizing its behavior is as simple as editing a file. Get started For installation and usage instructions, see the Getting started page of the wiki. Learn more The Chain Reactor documentation is available as a wiki. For information about the philosophy and development of the atomic family of projects, visit our website at https://atomicredteam.io.
