Author: Julia Kanaikina

DevSecOps, the abbreviation for Development, Security, and Operations, aims to incorporate security practices into the Software Development Life Cycle (SDLC). Automation, particularly security automation, plays a pivotal role in achieving this goal, numerous benefits being provided, such as accelerated development and deployment, enhanced collaboration, and heightened security. The present article explores the concept of DevSecOps automation and its integration within the SDLC delving into the intricacies of each stage and the various tools and methodologies employed.

Introduction

DevSecOps, an evolutionary step forward from the traditional DevOps approach, focuses on integrating security within the software development process. The successful implementation of DevSecOps automation necessitates utilization of various security automation tools, technologies, and practices throughout the SDLC. Security automation and security testing are fundamental parts of this process. The following stages detail these components and their application at each step of the software development process.

1. Planning and Analysis

• Threat Modeling: a systematic process to identify, quantify, and address potential security threats within an application. Utilization of specialized tools such as Microsoft’s Threat Modeling Tool, OWASP’s Threat Dragon, or securiCAD by foreseeti facilitates this endeavor. The process encompasses the evaluation of assets, trust boundaries, and potential attack vectors, as well as the application of threat intelligence and data flow analysis.
• Risk Assessment: a crucial practice in identifying and prioritizing vulnerabilities, employing frameworks and standards like CVSS (Common Vulnerability Scoring System), FAIR (Factor Analysis of Information Risk), or NIST SP 800-30 to assess and rank potential risks. Analyzing the likelihood and impact of vulnerabilities, teams can develop effective remediation strategies and prioritize resources based on risk severity.
• Security Requirements: defining and documenting security specifications during the initial planning phase, including access control, data encryption, and secure communication protocols. Incorporating security standards such as ISO/IEC 27001, NIST SP 800-53, or CIS Critical Security Controls ensures adherence to industry best practices and compliance with relevant regulations. Moreover, the application of Privacy by Design principles safeguards users’ data and privacy.
• Asset Inventory: compiling a comprehensive inventory of software and hardware assets, including their configurations and dependencies, is crucial for maintaining an accurate understanding of the system’s architecture.

2. Design and Architecture

• Secure Design Principles: adherence to best practices such as the OWASP Top Ten Proactive Controls, the SANS 25 Most Dangerous Software Errors, or the MITRE ATT&CK framework emphasizing data minimization, least privilege, and defense-in-depth strategies. The principles guide the development of robust secure applications by promoting a proactive approach to threat mitigation.
• Architecture Analysis: evaluation of application architecture to identify potential security flaws, utilizing security automation tools like OWASP’s Dependency-Check, Sonatype’s Nexus Lifecycle, or Snyk for analyzing third-party dependencies and uncovering potential vulnerabilities. This analysis also includes the use of threat modeling methodologies such as STRIDE (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege) or PASTA (Process for Attack Simulation and Threat Analysis) to assess the application’s attack surface.
• Security Patterns: implementation of established security design patterns, such as the Singleton Pattern, the Factory Pattern, or the Principle of Least Privilege, to bolster application security. The patterns can be complemented by architectural patterns like Microservices, Serverless, or Containerization which provide additional security benefits by isolation, scalability, and enhanced deployment flexibility.

3. Development and Implementation

• Secure Coding Practices: ensuring developers adhere to secure coding standards, including OWASP’s Secure Coding Practices, CERT’s Secure Coding Standards, or SEI’s Coding Standards. Following these guidelines developers can prevent vulnerabilities resulting from common coding errors, such as improper input validation, insufficient error handling, or insecure data storage.
• Static Application Security Testing (SAST): automated code analysis using tools like SonarQube, GitLab SAST, Veracode, or Fortify to identify vulnerabilities in source code. SAST tools perform deep code scanning, control and data flows analysis, and security flaws detection, such as SQL Injection, Cross-Site Scripting (XSS), or Insecure Deserialization. Integrating SAST into the development process enables early vulnerability detection and remediation, thus reducing potential risks.
• Software Composition Analysis (SCA): analysis of open-source components and libraries utilizing tools such as WhiteSource, Black Duck, or Snyk to identify known security vulnerabilities. SCA tools examine an application’s dependencies, detecting outdated or insecure components, and providing actionable insights to remediate identified issues. Regular updating dependencies and monitoring for security advisories help maintain a secure and up-to-date application environment.
• Infrastructure as Code (IaC) Security: employing IaC tools like Terraform, Ansible, or Chef to automate infrastructure provisioning and configuration while integrating security checks using tools like Checkov or Kics. Incorporating security into IaC enables teams to enforce consistent security policies and configurations, thus enhancing the overall security posture of the application environment.

4. Testing and Validation

• Dynamic Application Security Testing (DAST): automated testing of running applications employing tools like OWASP’s Zed Attack Proxy (ZAP), Burp Suite, Acunetix or AppSpider to detect vulnerabilities. DAST tools simulate real-world attacks, such as SQL Injection, Cross-Site Scripting (XSS), or Cross-Site Request Forgery (CSRF), testing the application’s resilience and identifying security weaknesses during runtime. This form of security testing plays a vital role in securing applications.
• Interactive Application Security Testing (IAST): combining SAST and DAST approaches utilizing tools like Contrast Security, Seeker, or HCL AppScan to identify vulnerabilities and code execution paths. IAST tools monitor applications during runtime analyzing data flows, HTTP requests, and responses and providing real-time feedback to developers. The approach enhances the accuracy of vulnerability detection and facilitates rapid remediation.
• Penetration Testing: conducting simulated attacks on the application leveraging tools like Metasploit, Nmap, or Cobalt Strike to identify and address security vulnerabilities. Penetration testing methodologies, such as the Open Web Application Security Project (OWASP) Testing Guide or the Penetration Testing Execution Standard (PTES), provide a structured approach to security testing ensuring comprehensive coverage of potential threats.
• Fuzz Testing: employing advanced testing techniques like fuzz testing using tools such as AFL, Peach Fuzzer, or Boofuzz to identify potential vulnerabilities in the application. Fuzz testing involves sending large volumes of random, malformed, or unexpected input data to the application aiming to trigger unintended behavior, crashes, or security vulnerabilities.
• Compliance and Security Audits: conducting regular audits to ensure compliance with relevant regulatory standards, such as GDPR, HIPAA, or PCI DSS, and adherence to security best practices. Leveraging tools like OpenSCAP, Nessus, or Qualys Policy Compliance simplify the audit process and help organizations maintain a secure and compliant application environment.
• Security Test Driven Development (STDD): integrating security testing into the development process with a focus on writing security test cases alongside with functional test cases. This approach promotes a security-focused mindset enabling developers to address potential vulnerabilities as they arise during development.

5. Deployment and Monitoring

• Continuous Integration and Continuous Deployment (CI/CD): streamlining the development and deployment process leveraging tools like Jenkins, GitLab CI/CD, or CircleCI to ensure consistent and secure application updates. Integrating security tools such as SAST, DAST, or SCA into the CI/CD pipeline enhances the security posture by automating vulnerability detection and remediation throughout the development lifecycle.
• Security Information and Event Management (SIEM): aggregating and analyzing log data from various sources employing tools like Splunk, LogRhythm, or IBM QRadar to identify potential security incidents. SIEM tools provide real-time monitoring, advanced analytics, and incident response capabilities enabling organizations to detect, investigate, and respond to security threats effectively.
• Runtime Application Self-Protection (RASP): incorporating security measures directly into the application runtime utilizing security automation tools to detect and prevent attacks in real-time. RASP solutions monitor application behavior, identify malicious activities, and take appropriate actions, such as blocking the attack or alerting security personnel, providing an additional layer of protection against known and unknown threats.
• Vulnerability Management and Patch Management: regular scanning the application and its infrastructure for vulnerabilities and applying necessary patches, leveraging tools like Tenable Nessus, Rapid7 InsightVM, or Ivanti Patch Manager. A robust vulnerability and patch management program minimizes the window of opportunity for attackers to exploit known vulnerabilities and helps maintain a secure application environment.
• Incident Response and Forensics: developing and maintaining a comprehensive incident response plan, incorporating digital forensics tools like Autopsy, EnCase, or X-Ways Forensics, to effectively address security incidents. A well-prepared incident response strategy enables organizations to swiftly detect, contain, and remediate security breaches minimizing potential damages and facilitating the recovery process.
• Network Security Monitoring (NSM): implementing network monitoring and intrusion detection systems using tools like Suricata, Snort, or Zeek to detect and respond to security events at the network level. NSM tools analyze network traffic, identify suspicious activities, and provide insights into potential threats facilitating rapid incident response and remediation.
