Bearer – A Quick Guide To Scanning And Securing Your Application

Discover your application security risks and vulnerabilities in only a few minutes. In this guide you will install Bearer CLI, run the SAST scanner on a local project, and view the results of a security report. Let’s get started!

Installation

The quickest way to install Bearer CLI is with the install script. It will auto-select the best build for your architecture. Defaults installation to ./bin and to the latest release version:

curl -sfL https://raw.githubusercontent.com/Bearer/bearer/main/contrib/install.sh | sh

Or, if your platform supports it, with Homebrew using Bearer CLI’s official Homebrew tap:

brew install Bearer/tap/bearer

If you need more control or another way to install Bearer CLI, we offer more installation options.

Scan Your Project

The easiest way to try out Bearer CLI is with the OWASP Juice Shop example project. Clone or download it to a convenient location to get started.

git clone https://github.com/juice-shop/juice-shop.git

Now, run the scan command with bearer scan on the project directory:

bearer scan juice-shop

A progress bar will display the status of the scan.

Once the scan is complete, Bearer CLI will output a security report with details of any rules findings, as well as where in the codebase the infractions happened.

By default the scan command uses the SAST scanner; other scanner types are also available.

Analyze The R eport

The security report is an easily digestible view of the security findings detected by Bearer CLI. A report is made up of:

• The list of rules run against your code.
• Each detected finding, containing the file location and lines that triggered the rules finding.
• A stat section with a summary of rules checks, findings and warnings.

The OWASP Juice Shop example application will trigger rule findings and output a full report. Here’s a section of the output containing a finding snippet and the final summary:

...
HIGH: Sensitive data stored in HTML local storage detected. [CWE-312]

To skip this rule, use the flag --skip-rule=javascript_lang_session

File: juice-shop/frontend/src/app/login/login.component.ts:102

 102       localStorage.setItem('email', this.user.email)


=====================================

59 checks, 40 findings

CRITICAL: 0
HIGH: 16 (CWE-22, CWE-312, CWE-798, CWE-89)
MEDIUM: 24 (CWE-327, CWE-548, CWE-79)
LOW: 0
WARNING: 0

In addition of the security report, you can also run a privacy report.
