  1. Copy the folder ~/.kube from Kubernetes master node to Build VM
  2. Create SSH Key on Build VM to access Kubernetes master node
Vuls

We use Ubuntu 20.04, and behind a proxy, so we run Vuls test as follows:

  1. Create directory

    $ mkdir ~/vuls
    $ cd ~/vuls
    $ mkdir go-cve-dictionary-log goval-dictionary-log gost-log
    


  2. Fetch NVD

    $ docker run --rm -it \
        -v $PWD:/go-cve-dictionary \
        -v $PWD/go-cve-dictionary-log:/var/log/go-cve-dictionary \
        vuls/go-cve-dictionary fetch nvd --http-proxy $http_proxy
    


  3. Fetch OVAL

    $ docker run --rm -it \
         -v $PWD:/goval-dictionary \
         -v $PWD/goval-dictionary-log:/var/log/goval-dictionary \
         vuls/goval-dictionary fetch ubuntu 14 16 17 18 19 20 --http-proxy $http_proxy
    


  4. Fetch gost

    $ docker run --rm -iit \
    -e http_proxy=$http_proxy \
    -e https_proxy=$https_proxy \ -v $PWD:/gost \ -v $PWD/gost-log:/var/log/gost \ vuls/gost fetch ubuntu --http-proxy $http_proxy


  5. Create config.toml

    [servers]
    
    [servers.master]
    host = "192.168.51.22"
    port = "22"
    user = "test-user"
    keyPath = "/root/.ssh/id_rsa" # path to ssh private key in docker
    


  6. Start vuls container to run tests

    $ docker run --rm -it \
        -v ~/.ssh:/root/.ssh:ro \
        -v $PWD:/vuls \
        -v $PWD/vuls-log:/var/log/vuls \
        -v /etc/localtime:/etc/localtime:ro \
        -v /etc/timezone:/etc/timezone:ro \
        vuls/vuls scan \
        -config=./config.toml
     \
       --http-proxy $http_proxy


  7. Get the report

    $ docker run --rm -it \
         -v ~/.ssh:/root/.ssh:ro \
         -v $PWD:/vuls \
         -v $PWD/vuls-log:/var/log/vuls \
         -v /etc/localtime:/etc/localtime:ro \
         vuls/vuls report \
         -format-list \
         -config=./config.toml
     \
     --http-proxy $http_proxy

  1. Create ~/validation/bluval/bluval-sdtfc.yaml to customize the Test

    blueprint:
        name: sdtfc
        layers:
            - k8s
    - os k8s: &k8s - name: kube-hunter what: kube-hunter optional: "False"

    os: &os
    -
    name: lynis
    what: lynis
    optional: "False"


  2. Update ~/validation/bluval/volumes.yaml file

    volumes:
        # location of the ssh key to access the cluster
        ssh_key_dir:
            local: '/home/ubuntu/.ssh'

            - openrc
        sds:
        sdn:
        vim:
    


  3. Update ~/validation/tests/variables.yaml file

    ### Input variables cluster's master host
    host: <IP Address>             # cluster's master host address
    username: <username>            # login name to connect to cluster
    password: <password>         # login password to connect to cluster
    ssh_keyfile: /root/.ssh/id_rsa        # Identity file for authentication
    


  4. Run Blucon

    $ bash validation/bluval/blucon.sh sdtfc

2022-09-14 16:19:49 Test: Checking for program update...
2022-09-14 16:19:49 Result: Update check failed. No network connection?
2022-09-14 16:19:49 Info: to perform an automatic update check, outbound DNS connections should be allowed (TXT record).
2022-09-14 16:19:49 Suggestion: This release is more than 4 months old. Check the website or GitHub to see if there is an update available. [test:LYNIS] [details:-] [solution:-]

The test environment is a proxied private network inside the Fujitsu corporate network which does not allow direct DNS lookups using tools such as dig. Therefore the update check cannot be performed automatically.

The latest version of Lynis, 3.0.8 at time of execution, was downloaded and Note: Lynis was downloaded and run directly on the SUT. See the link below:
