DevSecOps: Everything you need to know

‍

Key Features and Services in DevSecOps

Threat Modeling

Threat modeling involves viewing the application from the perspective of a potential attacker to identify and address vulnerabilities early in the development process. For example, Before launching a new banking app, developers create scenarios where an attacker tries to bypass security measures to steal customer data. Identifying these threats helps in building robust security features.

What are the top open-source Threat modeling tools?

The top open-source threat modeling tools include:

OWASP Threat Dragon: A free, open-source threat modeling application that is powerful and easy to use. It can be used for categorizing threats using STRIDE, LINDDUN CIA, DIE, and PLOT4ai. It runs as both a web application and a desktop application.

Microsoft Threat Modeling Tool: An open-source tool that helps identify threats during the design phase of software projects. It supports the STRIDE methodology and provides a guided process with a visual interface.

Threagile: An open-source toolkit for agile threat modeling. It offers an agile approach to threat modeling and automates threat identification and mitigation suggestions.

PyTM: An open-source project providing a library for threat modeling with code. It generates threat modeling reports automatically based on system descriptions using OO syntax.

These tools offer a range of features and methodologies to support threat modeling and enhance software security during development.

IDE Security Plugins

Integrated Development Environment (IDE) security plugins and pre-commit hooks enable lightweight static analysis checks within the development environment. For example, A plugin in Visual Studio Code might scan the code for vulnerabilities before it’s even committed to the repository, catching issues early in the development process.

What are the top open-source IDE Security plugins?

The top open-source IDE security plugins include:

Snyk Security Scanner: Provides real-time vulnerability scanning of code, open source libraries, containers, and cloud infrastructure, offering actionable fix advice in-line with code.

Grype: The Grype extension makes it easy to know when your project is using dependencies that have known security vulnerabilities.

Trivy Vulnerability Scanner: Helps find vulnerabilities in software projects without leaving the comfort of your VS Code window.

OWASP Dependency Track: A continuous component analysis platform for identifying and managing open-source dependencies.

These plugins integrate security checks directly into the development environment, enabling early detection and remediation of vulnerabilities.

Application Security Tools (AST)

Application Security Tools (AST) are specialized software tools designed to identify, mitigate, and manage application vulnerabilities throughout their development lifecycle. AST encompasses a wide range of technologies and methodologies, each tailored to address different aspects of application security. These tools help ensure that applications are secure from the earliest stages of development through deployment and beyond.

• Open Source Analysis (OSA)
  • Evaluates the use of open-source components within an application to ensure they are secure. For example, tools like Snyk Security Scanner, Black Duck can identify vulnerabilities in open-source libraries used in a project.
• Software Composition Analysis (SCA)
  • Analyzes software to identify open-source components and their associated risks. For example, SCA tools can alert you if a known vulnerability exists in a library your application relies on. Grype offers SCA.
• Static Application Security Testing (SAST)
  • Examines source code to find security vulnerabilities without executing the code. For example, tools like SonarQube can detect issues like SQL injection or cross-site scripting (XSS) in your codebase. OWASP ZAP is one the most prominent open-source SAST tool.
• Dynamic Application Security Testing (DAST)
  • Tests the application in its running state to identify vulnerabilities. For example, OWASP ZAP can scan your live application for security flaws. Ethiack, Secureblink and others offer this as a service on Ofofo.
• Interactive Application Security Testing (IAST)
  • Combines aspects of SAST and DAST by analyzing running applications and their code simultaneously. For example, Contrast Security provides insights by monitoring the application during runtime.
• Behavioral Application Security Testing (BAST)
  • Observes the behaviour of an application to detect security issues. For example, monitoring user behaviour to detect anomalies that might indicate a security breach.
• Runtime Application Self-Protection (RASP)
  • Integrates security directly into the runtime environment to detect and prevent real-time attacks. For example, a RASP tool can block SQL injection attempts by analyzing database queries in real-time.
• API Security Testing (API ST)
  • Ensures APIs are secure by testing for vulnerabilities. For example, Tools like Postman can test the security of API endpoints.
• Bytecode and Container Analysis (BCA)
  • Analyzes bytecode and container images for vulnerabilities. For example, Scanning Docker images for known vulnerabilities before deployment.
• Application Security Orchestration and Correlation (ASOC)
  • Coordinates various security tools and integrates their findings for comprehensive vulnerability management.

Acunetix, Checkmarx IAST, Contrast Assess, Ethiack, Secureblink, OWASP ZAP, Grype, Snyk Security Scanner, Black Duck offer AST capabilities.
