Running a Scan

Requirements: Privado requires Docker and an Internet connection for fetching its scanning engine (provided as Docker images) for the first time. To install docker, you can follow the steps stated in the official documentation. Linux users should also follow docker post installation steps in order to run Privado CLI without root (sudo) privileges.
The simplest way to run a Privado scan is by just doing,
privado scan <source directory>
This begins analyzing the app, fetching/updating the analysis engine and then performing the scan of target source directory locally.
Upon completion, results are generated locally under <source directory>/.privado/privado.json file. This file contains all the information such as discovered data elements, data inventory, data flows to 3rd party, logs, and other sensitive sinks etc. Optionally, when configured, the scan can also send its results to Privado dashboard for visualisation.

Advanced Scan Options

You can view all advanced options using privado scan --help and can be run using privado scan <source directory> [OPTIONS] A few of the options are summarized below
--config
Specifies the config (with rules) directory to be passed to privado-core for scanning. These external rules and configurations are merged with the default set that Privado defines

--debug
Shows debug information while running
--upload
If specified, will automatically attempt to upload the scan result to Privado Dashboard
--skip-upload
If specified, the result artifacts will not be uploaded to Privado Dashboard
--disable-deduplication
When specified, the engine does not remove duplicate and subset dataflows. This option is useful if you wish to review all flows (including duplicates) manually.

--ignore-default-rules
If specified, the default rules are ignored and only the specified rules via configuration are considered

--overwrite
If specified, the warning prompt for existing scan results is disabled and any existing results are overwritten
--skip-dependency-download
Occasionally for Java projects, Privado would require dependencies to be downloaded for a more deeper analysis if local dependencies are not available. If an analysis takes unacceptable amount of time due to network latency, this option can be used to skip dependency downloads at the cost of incomplete results

Troubleshooting

Scan Time Out

While Privado scans rarely take more than 7 minutes even for very large java repositories, static analysis due to its nature can be a resource intensive process. If your scan is timing out, try the following approaches to manage resources used by Docker and JVM:
  1. 1.
    Limit the RAM consumed by docker. Reference: Runtime options with Memory, CPUs, and GPUs](https://docs.docker.com/config/containers/resource_constraints/)
  2. 2.
    Specific to Java, we can also set the env variables of docker according to host machine configuration, Reference: How To Configure Java Heap Size Inside a Docker Container | Baeldung](https://www.baeldung.com/ops/docker-jvm-heap-size)
