5eccb498c1 FIX| RKE-CIS-1.24- CHECK 1.1.19 (#1722)
We have added the missing script required for check 1.1.19 in rke-cis-1.24 and made it available to the kube-bench file system(https://github.com/rancher/security-scan/blob/master/package/helper_scripts/check_files_owner_in_dir.sh).

f6877e3c17 Fix issue 1595: failed to output to ASFF (#1691)
A breaking change was introduced in aws-sdk-go-v2.
See https://github.com/aws/aws-sdk-go-v2/issues/2370#issuecomment-1953308268.

Mixing aws-sdk-go-v2 packages from versions before and after the breaking change causes kube-bench to fail. This issue occurs when it attempts to access AWS Security Hub.

Addressed issue: https://github.com/aquasecurity/kube-bench/issues/1595

Supersedes bot PR: https://github.com/aquasecurity/kube-bench/pull/1689
Besides upgrading to latest SDK version, some variable types need to be adapted.

d2d3e72271 Currently, certain commands involve retrieving all node names or pods and then executing additional commands in a loop, resulting in a time complexity linearly proportional to the number of nodes. (#1597)
This approach becomes time-consuming for larger clusters.

As kube-bench is executed as a job on every node in the cluster, To enhance performance, Streamlined the commands to execute directly on current node where kube-bench operates.
This change ensures that the time complexity remains constant, regardless of the cluster size.
By running the necessary commands only once per node, regardless of how many nodes are in the cluster, this approach significantly boosts performance and efficiency.

Review the audit policy provided for the cluster and ensure that it covers
at least the following areas,
- Access to Secrets managed by the cluster. Care should be taken to only
log Metadata for requests to Secrets, ConfigMaps, and TokenReviews, in
order to avoid risk of logging sensitive data.
- Modification of Pod and Deployment objects.
- Use of `pods/exec`, `pods/portforward`, `pods/proxy` and `services/proxy`.
For most requests, minimally logging at the Metadata level is recommended
(the most basic level of logging).

Remediation Method 1:
If configuring via the Kubelet config file, you first need to locate the file.
To do this, SSH to each node and execute the following command to find the kubelet
process:
ps -ef | grep kubelet
The output of the above command provides details of the active kubelet process, from
which we can see the location of the configuration file provided to the kubelet service
with the --config argument. The file can be viewed with a command such as more or
less, like so:
sudo less /home/kubernetes/kubelet-config.yaml
Disable Anonymous Authentication by setting the following parameter:
"authentication": { "anonymous": { "enabled": false } }
Remediation Method 2:
If using executable arguments, edit the kubelet service file on each worker node and
ensure the below parameters are part of the KUBELET_ARGS variable string.
For systems using systemd, such as the Amazon EKS Optimised Amazon Linux or
Bottlerocket AMIs, then this file can be found at
/etc/systemd/system/kubelet.service.d/10-kubelet-args.conf. Otherwise,
you may need to look up documentation for your chosen operating system to determine
which service manager is configured:
--anonymous-auth=false
For Both Remediation Steps:
Based on your system, restart the kubelet service and check the service status.
The following example is for operating systems using systemd, such as the Amazon
EKS Optimised Amazon Linux or Bottlerocket AMIs, and invokes the systemctl

remediation: |
Review the audit policy provided for the cluster and ensure that it covers
at least the following areas,
- Access to Secrets managed by the cluster. Care should be taken to only
log Metadata for requests to Secrets, ConfigMaps, and TokenReviews, in
order to avoid risk of logging sensitive data.
- Modification of Pod and Deployment objects.
- Use of `pods/exec`, `pods/portforward`, `pods/proxy` and `services/proxy`.
For most requests, minimally logging at the Metadata level is recommended
(the most basic level of logging).
