What is SSH_scan?

SSH_scan is an easy-to-use prototype SSH configuration and policy scanner, inspired by Mozilla OpenSSH Security Guide, which provides a reasonable baseline policy recommendation for SSH configuration parameters such as Ciphers, MACs, and KexAlgos and much more.

To learn more about the ssh_scan scanner itself visit ssh_scan GitHub.

Deployment

The ssh-scan chart can be deployed via helm:

# Install HelmChart (use -n to configure another namespace)
helm upgrade --install ssh-scan secureCodeBox/ssh-scan

Scanner Configuration

The following security scan configuration example are based on the ssh_scan Documentation, please take a look at the original documentation for more configuration examples.

ssh_scan v0.0.21 (https://github.com/mozilla/ssh_scan)

Usage: ssh_scan [options]
    -t, --target [IP/Range/Hostname] IP/Ranges/Hostname to scan
    -f, --file [FilePath]            File Path of the file containing IP/Range/Hostnames to scan
    -T, --timeout [seconds]          Timeout per connect after which ssh_scan gives up on the host
    -L, --logger [Log File Path]     Enable logger
    -O, --from_json [FilePath]       File to read JSON output from
    -o, --output [FilePath]          File to write JSON output to
    -p, --port [PORT]                Port (Default: 22)
    -P, --policy [FILE]              Custom policy file (Default: Mozilla Modern)
        --threads [NUMBER]           Number of worker threads (Default: 5)
        --fingerprint-db [FILE]      File location of fingerprint database (Default: ./fingerprints.db)
        --suppress-update-status     Do not check for updates
    -u, --unit-test [FILE]           Throw appropriate exit codes based on compliance status
    -V [STD_LOGGING_LEVEL],
        --verbosity
    -v, --version                    Display just version info
    -h, --help                       Show this message

Examples:

  ssh_scan -t 192.168.1.1
  ssh_scan -t server.example.com
  ssh_scan -t ::1
  ssh_scan -t ::1 -T 5
  ssh_scan -f hosts.txt
  ssh_scan -o output.json
  ssh_scan -O output.json -o rescan_output.json
  ssh_scan -t 192.168.1.1 -p 22222
  ssh_scan -t 192.168.1.1 -p 22222 -L output.log -V INFO
  ssh_scan -t 192.168.1.1 -P custom_policy.yml
  ssh_scan -t 192.168.1.1 --unit-test -P custom_policy.yml

Values

Key Type Default Description
cascadingRules.enabled bool true Enables or disables the installation of the default cascading rules for this scanner
parser.affinity object {} Optional affinity settings that control how the parser job is scheduled (see: https://kubernetes.io/docs/tasks/configure-pod-container/assign-pods-nodes-using-node-affinity/)
parser.env list [] Optional environment variables mapped into each parseJob (see: https://kubernetes.io/docs/tasks/inject-data-application/define-environment-variable-container/)
parser.image.pullPolicy string "IfNotPresent" Image pull policy. One of Always, Never, IfNotPresent. Defaults to Always if :latest tag is specified, or IfNotPresent otherwise. More info: https://kubernetes.io/docs/concepts/containers/images#updating-images
parser.image.repository string "docker.io/securecodebox/parser-ssh-scan" Parser image repository
parser.image.tag string defaults to the charts version Parser image tag

parser.ttlSecondsAfterFinished string nil seconds after which the kubernetes job for the parser will be deleted. Requires the Kubernetes TTLAfterFinished controller: https://kubernetes.io/docs/concepts/workloads/controllers/ttlafterfinished/
scanner.activeDeadlineSeconds string nil There are situations where you want to fail a scan Job after some amount of time. To do so, set activeDeadlineSeconds to define an active deadline (in seconds) when considering a scan Job as failed. (see: https://kubernetes.io/docs/concepts/workloads/controllers/job/#job-termination-and-cleanup)
scanner.affinity object {} Optional affinity settings that control how the scanner job is scheduled (see: https://kubernetes.io/docs/tasks/configure-pod-container/assign-pods-nodes-using-node-affinity/)
scanner.backoffLimit int 3 There are situations where you want to fail a scan Job after some amount of retries due to a logical error in configuration etc. To do so, set backoffLimit to specify the number of retries before considering a scan Job as failed. (see: https://kubernetes.io/docs/concepts/workloads/controllers/job/#pod-backoff-failure-policy)
scanner.env list [] Optional environment variables mapped into each scanJob (see: https://kubernetes.io/docs/tasks/inject-data-application/define-environment-variable-container/)
scanner.extraContainers list [] Optional additional Containers started with each scanJob (see: https://kubernetes.io/docs/concepts/workloads/pods/init-containers/)
scanner.extraVolumeMounts list [] Optional VolumeMounts mapped into each scanJob (see: https://kubernetes.io/docs/concepts/storage/volumes/)
scanner.extraVolumes list [] Optional Volumes mapped into each scanJob (see: https://kubernetes.io/docs/concepts/storage/volumes/)
