Change node check 2.1.6 to use operation `noteq` instead of `gt`.

Abubakr-Sadik Nii Nai Davis
3e3aa0ed82 Change node check 2.1.6 to use operation noteq instead of gt.
Kubelet option --streaming-connection-idle-timeout expects a string
value which fails parsing to integer for greater than comparison.

The string "0" indicates no timeout and this is what we are checking
for.

d2fa9d35b6 Rewrite audit commands in the check definition that contain shell builtins
and modify text to command function to support this.

Shell builtins fail the binary command lookup test which result in a
WARN. Audit commands which include shell builtins must use the form:

   "/bin/sh -c 'sh-builtin arg'"

So they are executed properly. Additionally Go will fail to execute
commands involving shell builtins if they are not in the above format.

The Kubernetes Bench for Security is a Go application that checks whether Kubernetes is deployed securely by running the checks documented in the CIS Kubernetes 1.6 Benchmark v1.0.0.
The Kubernetes Bench for Security is a Go application that checks whether Kubernetes is deployed securely by running the checks documented in the CIS Kubernetes Benchmark.
Tests are configured with YAML files, making this tool easy to update as test specifications evolve.

## CIS Kubernetes Benchmark support
kube-bench supports the tests for multiple versions of Kubernetes (1.6, 1.7 and 1.8) as defined in the CIS Benchmarks 1.0.0, 1.1.0 and 1.2.0 respectively. It will determine the test set to run based on the Kubernetes version running on the machine.

Run ```docker run --rm -v `pwd`:/host aquasec/kube-bench:latest```. This will copy the kube-bench binary and configuration to you host. You can then run ```./kube-bench <master|node>```.

If Go is installed on the target machines, you can simply clone this repository and run as follows:

## Configuration
Kubernetes config and binary file locations and names can vary from installation to installation, so these are configurable in the `cfg/config.yaml` file.
They also tend to vary according to which tool was used to install Kubernetes. You can use the `--installation` flag to pick up a different default set of file names and locations. Again these defaults are configurable through `cfg/config.yaml` (and pull requests to correct or add default file locations are especially welcome).
For each type of node (*master*, *node* or *federated*) there is a list of components, and for each component there is a set of binaries (*bins*) and config files (*confs*) that kube-bench will look for (in the order they are listed). If your installation uses a different binary name or config file location for a Kubernetes component, you can add it to `cfg/config.yaml`.
* **bins** - If there is a *bins* list for a component, at least one of these binaries must be running. The tests will consider the parameters for the first binary in the list found to be running.
* **podspecs** - From version 1.2.0 of the benchmark (tests for Kubernetes 1.8), the remediation instructions were updated to assume that the configuration for several kubernetes components is defined in a pod YAML file, and podspec settings define where to look for that configuration.
* **confs** - If one of the listed config files is found, this will be considered for the test. Tests can continue even if no config file is found. If no file is found at any of the listed locations, and a *defaultconf* location is given for the component, the test will give remediation advice using the *defaultconf* location.
* **unitfiles** - From version 1.2.0 of the benchmark (tests for Kubernetes 1.8), the remediation instructions were updated to assume that kubelet configuration is defined in a service file, and this setting defines where to look for that configuration.
## Test config YAML representation
The tests are represented as YAML documents (installed by default into ./cfg).

# Roadmap
Going forward we plan to release updates to kube-bench to add support for new releases of the Benchmark, which in turn we can anticipate being made for each new Kubernetes release.
We welcome PRs and issue reports.
