Application security is a field that has continually evolved with the rapid advancements in software development and deployment practices. Today, organizations deploy applications faster than ever, leveraging DevOps practices and agile methodologies. While this speed is beneficial from a business perspective, it often leaves security lagging. Enter Application Security Testing Orchestration (ASTO). This approach integrates security into your application development life cycle, making it both efficient and effective.

What is Application Security Testing Orchestration (ASTO)?

ASTO is the strategic orchestration and automation of various application security testing (AST) tools throughout the Software Development Life Cycle (SDLC). Rather than a standalone security phase that happens late in the cycle, ASTO embeds security checks and validations at multiple points, effectively "shifting left" security considerations. This harmonization of tools and practices enables organizations to detect and respond to security vulnerabilities much more effectively than traditional methods.

Why ASTO is Essential

A Complex Security Landscape

Applications today are built using a myriad of technologies, frameworks, and third-party components, each introducing its own set of potential vulnerabilities. Simple code scans or penetration tests are often insufficient to identify and fix these complexities.

Speed of Development

With the rise of DevOps and CI/CD pipelines, the time from code commit to deployment has reduced significantly. Without an orchestrated approach to application security, vulnerabilities can easily slip through these fast-paced pipelines.

The Components of ASTO

  1. Orchestration Engine: This central hub coordinates between different AST tools, developer platforms, and security dashboards.
  2. Test Suite: A collection of specialized AST tools that can handle everything from Static Application Security Testing (SAST) to Dynamic Application Security Testing (DAST), and even Interactive Application Security Testing (IAST).
  3. Policy Manager: Defines the security policies, compliance guidelines, and testing parameters that must be followed.
  4. Results Analyzer: Compiles test results from various tools, eliminates false positives, and ranks vulnerabilities based on severity and impact.
  5. Feedback Loops: These mechanisms ensure that relevant information flows back into the development and security processes for ongoing improvement.

ASTO Tools and Technologies

SAST Tools

  • Checkmarx: Primarily focuses on source code analysis.

DAST Tools

  • OWASP ZAP: An open-source tool for finding vulnerabilities in web applications during runtime.

IAST Tools

  • Contrast Security: Integrates directly into the application, providing real-time vulnerability monitoring.

ASTO vs Traditional Application Security Testing

  1. Coverage: ASTO aims for broader coverage by employing multiple types of tests in an orchestrated manner. Traditional AST might miss out on this holistic view.
  2. Automation: ASTO leverages automation to the fullest, reducing human errors and speeding up the testing process. In contrast, traditional methods are often manual and time-consuming.
  3. Compliance: ASTO’s centralized Policy Manager makes it easier to enforce and track compliance metrics, something which can be a logistical nightmare in fragmented AST approaches.

Best Practices in ASTO

  1. Define Clear Policies: A well-defined security policy is the backbone of any effective ASTO strategy.
  2. Integrated Development Environment (IDE) Scanning: Integrate SAST tools directly into the developers' IDE to catch vulnerabilities early.
  3. Regular Updates: Regularly update your AST tools and policies to adapt to new security challenges.
  4. Train Your Team: Cybersecurity Awareness Training can arm your development and security teams with the knowledge they need to recognize and address security issues proactively.

Challenges in ASTO and Solutions

  1. Tool Fragmentation: Use an Orchestration Engine to centralize all your AST tools.
  2. False Positives: Employ a Results Analyzer to automatically sort through the noise, focusing only on genuine threats.
  3. Resource Constraints: Managed services like SubRosa’s Application Security Testing can supplement your internal teams and provide the specialized skills required for effective ASTO.
