Free and Inexpensive Security Testing Tools for DevOps

In this article:

Every DevOps team should employ application security testing tools in this day and age and constant incoming news of companies being hacked and ransomed for millions. So, it pays off to make security testing part of the DevOps tools stack in the short, mid, and long term.

And while software development teams often move fast with the single goal of satisfying business needs and shipping features, having security professionals take care of the security issues is often an expensive and unnecessary organizational approach.

Let’s look into the top application security testing tools available out there and the type of vulnerabilities you can cover without needing in-house security teams or penetration testers. 



What Are Security Testing Tools?

Security testing tools blend into a DevOps workflow strategically, forming a DevSecOps model while improving production efficiency and minimizing software development costs.

Such tools allow you to include testing and remediation of potential application vulnerabilities throughout the Software Development Lifecycle (SDLC) and post-delivery Run & Maintain phases. Thus, enabling a DevSecOps model ensures developers adopt a secured development and delivery cycle without lagging productivity and attributing ‘security’ at the bottom of the SDLC.

The DevSecOps paradigm continues to evolve, and with the emergence of distinct application security tools, organizations can now test and secure different software development and delivery stages. DevSecOps security tools are most commonly categorized into Static Application Security Testing (SAST) and Dynamic Application Security Testing (DAST) methodologies.

This article will look at the prominently used security tools and approaches.

Static Application Security Testing (SAST) Tools

SAST models on a multiform of Source Code Analysis, Binary Analysis, and White Box Testing Techniques. At a glance, SAST tools examine an application’s source code for security vulnerabilities, usually before the code is pushed to production. For example, a SAST Source Code Analysis involves testing static code for vulnerable defects such as race conditions, input validation, numerical errors, etc.

On the other hand, Binary Analysis requires testing for these defects in code that have been built and compiled. With many SAST tools, some test only the source code, some test the compiled code, while some test both source and compiled code.

Below are a few notable SAST tools:

LGTM.COM

LGTM is an open-source platform that checks code for Common Vulnerabilities and Exposures (CVEs) through variant analysis and is known to support major programming languages, including C/C++, Go, Java, JavaScript/TypeScript, C#, and Python. Primarily, LGTM uses CodeQL technology to identify an issue, fix it, and scan for similar code patterns to avoid further threats. In addition, LGTM uses open-source projects on various repository systems to perform an automated code review, identifying exposures in the source code.

Being an open-source platform, LGTM leverages security experts’ knowledge as contributors who use data science and semantic code search to write queries that detect existing and new code vulnerabilities.

SonarQube

SonarQube is one of the most prominent static code analysis tools designed to clean and secure DevOps workflows and code. SonarQube performs periodic reviews to detect bugs and security susceptibilities through continuous code quality analysis. In addition, SonarQube claims to scan code written in 27 programming languages, including Java, Python, C#, C/C++, Swift, PHP, COBOL, and Javascript, which essentially makes it perfect for teams with varying programming backgrounds or apps that run on multiple platforms.

More so, SonarQube can analyze your code in repositories like GitHub, Azure DevOps, and BitBucket, giving you instant feedback during code review.

The SonarQube community edition is free, open-source, and is popularly considered perfect for entry-level CI/CD Secure DevOps. On the other hand, its Developer, Enterprise, and Datacenter editions feature increasing sophistication levels for larger deployments.

Reshift

Reshift was designed to bring security posture to the attention without slowing down development, ideally making it one of the flag bearers promoting a DevSecOps model.

This tool integrates with an integrated development environment (IDE), making it near perfect for identifying and fixing vulnerabilities in real-time. As a key feature, Reshift allows you to secure your applications during code review, compile-time, and as part of continuous integration.

Reshift is considered a perfect lightweight DevOps Security Testing solution for SMBs and growing software companies looking to integrate security into their Software Development Lifecycle without requiring security expertise for usage.

Insider CLI

Insider CLI is another open-source SAST tool designed on OWASP Top 10 to ease security automation for various programming languages, including .NET framework, Javascript (Node.js), Java (Android and Maven), Swift, and C#.

The Insider Source Code Analysis tool is a community-driven security tool that supports agile and easy software development by scanning for source code-level vulnerabilities.

With Insider Application Security, you can secure your code directly on the GitHub directory using a free, integrated, and frictionless GitHub action, making it easy to secure your source code directly in your GitHub directory.

Dynamic Application Security Testing (DAST) Tools

DAST tools are also called Black Box Security Testing or Vulnerability Scanning tools. These tools test an application from an outsider’s perspective with limited to no knowledge of the written source code.

DAST tools simulate an attack vector’s action, testing the application during runtime to uncover potential security loopholes. In addition, these tools run without human intervention, automating the testing process with little to no manual intervention.

Vulnerabilities explored by DAST tools are reasonably broad, including memory corruption, cross-site request forgeryremote file inclusion, buffer overflow, and denial-of-service (DoS).

Crashtest Security

The Crashtest Security Suite is a security vulnerability scanning tool with advanced crawling to detect various vulnerabilities in web applications. In addition, screens can be automated by seamlessly integrating into the development pipeline to be part of the standard build and deployment process.

Crashtest Security is built with modern applications and development teams in mind. That means balancing enterprise-grade scans with a user-friendly interface, meaning you don’t have to be a security specialist to use Crashtest Security.
