Contribute to SRTool

Category:SRTool
This page summarizes the Security Response Tool (SRTool) development process. We hope this will help you start contributing to the project. The SRTool is based on the Yocto Project Toaster codebase (Django,Python,Javascript), so many of the process and debugging techniques apply.

== Set up the local repository and SRTool instance ==
1) Host requirements
The SRTool should in principle work on any host that supports Yocto Project. It requires "Python3", "Django >= 1.11", and "Sqlite3". A SQL GUI tool like 'sqlitebrowser' is recommended.
The required host package installation instructions are the same as Toaster, and the instructions can be found here: Toaster documentation
It was specifically developed and tested with:
Item 	Host 1 	Host 2	Host 3
Host 	Ubuntu 20.04	 	
Python3	3.8.10 	 	
Django 	4.00 	 	
Sqlite3	3.31.1 	 	
2) Cloning the SRTool
 $ git clone git://git.yoctoproject.org/srtool && cd srtool 
Here is the command if your SSH key is registered:
 $ git clone ssh://git@push.yoctoproject.org/srtool && cd srtool 
3) Starting the SRTool
Option #1: Restrict to the local browser:
 $ ./bin/srt start webport=localhost:9000 
Option #2: Enable remote browsers:
 $ ./bin/srt start webport=0.0.0.0:9000 
NOTE: The first time you run the SRTool, there will be a delay (30 to 60 minutes) as the default CVE repositories (NIST, Mitre, ...) are scanned, scored, and loaded into the database. After that, the updates will be incremental.
4) Create a superuser
You will need to create at least one super user account to promote users to higher permission levels:
 
 $ ./bin/srt manage createsuperuser 
5) Open browser to <IPADDR>:9000
This will bring up the SRTool page.
6) Read the "Guided Tour" 
Click on the "Guided Tour" button on the home page to see the on-line tool and user information.
7) Create your guest account
Click on the "Login" button in the top bar, select "Request Account", fill in the information, Click "Sign Up", and then log in.
8) Promote your account to Admin level
Login as the superuser, click "Management > Manage Users", click the edit icon for your guest account row, change the "Group" to "Admin", and click "Submit Changes".
You can now log out of the superuser account and into your own account.
== Sanity Test Bring-up ==
You can use these steps to start a minimal instance of the SRTool to help validate that the host and the code base are working on your system. This will for example set the environment variable "SRTDBG_MINIMAL_DB=1" which will only fetch a few representative records from each data source.
 $ # Clone the SRTool
 $ git clone git://git.yoctoproject.org/srtool && cd srtool 
 $ # Bring down the development assistance tools
 $ cp bin/dev_tools/* .
 $ # Prepare the venv and SRTool environment variables
 $ . prepare_environment.sh
 $ # Start the SRTool, trigger the CVE downloads
 $ ./restart.sh
 ...
 SRTool webserver started at http://0.0.0.0:9000
 $ # Create the initial superuser account, who can then create all other accounts
 $ ./super.sh 
 SRT_MAIN_APP=yp
 The system will manage.
 Username: srtool
 Email address: 
 Password: 
 Password (again): 
 Superuser created successfully.

Sanity command test:
 $ ./bin/common/srtool_sanity_test.py -i

 $ 
== First Time Bring-up ==
* When you first start, you will have the CVEs from 2015 to 2023
* You will not have any Vulnerabilities, Investigations, or Defects until you (a) create them, and/or (b) integrate your defect system or other sustaining data.
* All CVEs will by default get the status "Historical".
** The CVEs that were created in the previous 30 days will instead get the status "New"
** This will allow you to immediately test the CVE triage features
** The status settings are normally preset by your defect system or other sustaining data
* You can create a Vulnerability by:
** Selecting a CVE
** Click on "Create Vulnerability"
** Follow the new link to the new Vulnerability
* You can create an Investigation by:
** Open a Vulnerability record
** Click on "Add Product"
** Select one or more Products, and click "Submit"
** Observe that the products are added together with new respective Investigations
** Follow the new link to the new Investigations
* You can create a Defect by:
** Open an Investigation record
** Click on "Create Defect"
** With the sample defect integration script, a simulated defect will be created and attached to the investigation
== SRTool Primary Goals and Workflows ==
* Goals
** A common system to track and share security issues, combining community CVE's
** A simple yet flexible interface for reporting and exploring the security issues
** A place to upload and share attachments, including patches, fixes, emails, and documents
** The ability to generate accurate and up-to-date reports and exports
** A modular design for easy extension and adoption
* Primary Workflows
** Guide and manage the incoming CVE triage process
** Attach CVEs to specific company products and defects 
** Automated updates from upstream CVEs and internal defect system
** Ability to generate reports
** Simple customization for organizations
** Correlate CVEs with products and release (IN PROGRESS)
** Correlate CVEs with specific customer builds (IN PROGRESS)
== SRTool CVE Lifecycle ==
* CVE are imported
** New CVEs are imported and triaged from upstream (NIST/MITRE, 1000+/month)
** Specific CVEs are requested by customers
* CVEs are managed
** CVEs are investigated
** Vulnerable CVEs are assigned to products via defects
** SRTool manager tracks the progress of open CVEs
** SRTool manager produces reports as required by customers, field, and management
* CVEs are resolved
** CVEs are either fixed or declared not vulnerable
** Releases are updated with the CVE fixes
** Resolved CVEs are reported to customers, public website
== Testing the Alternate Sample Organization 'ACME' ==
* An example alternate organization (master application) called "acme" is included.
* This code shows all the ways the SRTool can be easily customized to the needs of your organization
* To enable it and try it out, do the following:
 $ # Include the quick development tools
 $ cp bin/dev_tools/* .
 $ # Reset 'acme' as the master app/organization
 $ ./stop.sh
 $ ./master_app.sh acme
 $ ./start.sh
* When you browse the SRTool pages, will now observe several differences
** In the top bar the text "[ACME]" will appear in several places. This shows how files like "lib/acme/templates/base.html" can take precedence over the default template files in "lib/srtgui". 
** In the top left corner the "ACME" logo will appear. This is from "SRTOOL_LOCAL_LOGO" being defined in "datasource.json".
** If you click on the ACME logo you will be taken to an ACME hello page. This shows that "lib/acme/urls.py" has extended the URL map, plus how you can implement basic HTML pages in ACME's "lib/acme/views.py" and "lib/acme/templates/acme_hello.html".
** In the ACME hello page, there are links to custom table pages for Products and Defects. This shows how to implement custom Toaster Tables via "lib/acme/urls.py" and "lib/acme/tables.py"
** In the Products page, when you click "Export" a new report type "ACME Products Table" is appended. This shows how to extend and customize existing or new reports.
* To restore the default "yp" master application, do the following:
 $ ./stop.sh
 $ ./master_app.sh yp
 $ ./start.sh
== Adapting SRTool to your Organization ==
* You can use the sample alternate organization "acme" as a guide to adapt SRTool to your organization
* In this example, we will instantiate a new organization called "yoyodyne"
* You should be able to place all of your local content into these two directories:
** "./bin/yoyodyne": this is your master datasource directory
** "./lib/yoyodyne": this is your master Django App directory
* If you find you need to make changes in the core SRTool code, we recommend (in preferential order):
** See if you can make it a generic feature so that it can become part of the mainline codebase
** See if you can make an easy hook for the mainline code, so that your custom content can still reside in your directories
** Talk to us on how to easily have managed custom patches to the mainline code (we do this in Toaster)
1) Instantiate your Organization
You can create a starting customization of the SRTool for your organization with these simple steps. 
* In this example, we will use the name "yoyo" as a shorthand for a mythical "Yoyodyne Corporation".
 $ cd /path_to/srtool_dir
 $ copy bin/dev_tools/* .
 $ ./stop.sh
 $ ./master_app.sh create yoyo
 $ ./start.sh
* This script will perform the following actions:
** Copy the sample 'bin/acme' directory to 'bin/yoyo'
** Copy the sample 'lib/acme' directory to 'lib/yoyo'
** Rename the respective Acme/ACME/acme labels and filenames to Yoyo/YOYO/yoyo
** Set 'yoyo' as the new main application
* You now have access to all the preset custom features described above for the ACME sample organization, now for Yoyodyne.
2) Add your defect system integration
You will need to implement a defect integration backend script to scan your defect system and instantiate the CVE defects in SRTool database, and then keep them up to date.
* An example implementation template for Jira is provided here. 
 bin/common/srtool_jira_template.py
* You can use this to guide your integration to Jira or to other defect systems.
* To see how to extend this template to your organization and yet maintain compatibility with upstream, see this section: Extending and customizing common/template code files
* Please contact the SRTool developers for assistance in your defect system integration effort.
The main features of this example code, in addition to the Jira system access, is:
* The "--init" command
** This command that will initialize the SRTool database with your SRT related defects. Specifically, this command can used to bootstrap the SRTool database for your company's data
** It will create an "Investigation" for each defect, and attach it to the respective product
** It will create a "Vulnerability" to wrap the respective "Investigation"
** If should find the respective CVE record if it exists, and attach that to the created "Vulnerability"
** If a "Vulnerability" record already exists for the defect's CVE, then this script should attach the new "Investigation" to that "Vulnerability" record.
* The "--update" command
** This will scan your CVE-related defects
** If the matching defect record in the SRTool database does not exist, then treat it like the "--init" command.
** It will update the SRTool defect record with the current defect system state
** If the defect has changed priority (or any other important state information), it will create a "Notification" event to the respective manager so that they can know that they need to act on the change.
* The example code assumes that the CVE names are available via a text-based search, for example when the respective CVE name is in the defect title or comments. If your system uses a different marker, then you will need to code for that.
