Securing the Development Life Cycle and CI/CD process.

In today’s fast-paced software development world, delivering secure applications is no longer a luxury—it’s a necessity. Traditional software development practices often treat security as an afterthought, addressing vulnerabilities only in the final stages of development or after release. This reactive approach not only increases the cost of fixing issues but also exposes systems to critical risks during production.

Shifting Left in the Software Development Life Cycle (SDLC) is a transformative approach that integrates security from the earliest stages of development. By embedding security into every phase—from planning and requirements gathering to testing and deployment—teams can identify and mitigate risks early, reducing vulnerabilities and saving both time and resources.

The Secure Software Development Life Cycle (SSDLC) builds upon the traditional SDLC by incorporating security-focused activities such as risk assessment, threat modeling, static code analysis, and secure configuration reviews. These practices help ensure that software is not only functional and efficient but also resilient to evolving security threats.

This blog explores the concept of Shifting Left and how implementing SSDLC principles can empower development teams to build secure software efficiently and proactively.

Pre-Phase:

Legal, Compliance, Administrative Security, Architecture.

Before technical development begins, securing the human factor is essential. This step ensures developers, contractors, and stakeholders are legally and ethically bound to protect sensitive information, intellectual property, and the integrity of the software development process.

1. Non-Disclosure Agreements (NDAs):

   • Require all developers, third-party contractors, and stakeholders to sign legally binding NDAs to protect sensitive project details, source code, and intellectual property.

     
     

2. Background Checks:

   • Conduct thorough background checks on all team members (developers, testers, admins) to identify any red flags related to:

     • Previous security breaches.

     • Insider threats or legal violations.

     • Employment history and relevant qualifications.

     • Criminal Records.

     
     

3. Legal and Compliance Documentation:

   • Enforce signing of legal agreements (e.g., IP ownership, data privacy agreements) to ensure compliance with global standards like GDPR, HIPAA, or PCI DSS.

   • Clearly define ownership of work and transfer of intellectual property rights in legal contracts.

   • Choose the right incorporation - LLC for example may provide you some protection in some cases if things gets of out of control.

   
   

4. Intellectual Property Protection:

   • File patents and trademarks for unique algorithms, processes, or innovations developed as part of the software lifecycle.

   • Use platforms like USPTO (U.S. Patent Office) or WIPO (World Intellectual Property Organization) for legal filings.

   • Implement code watermarking or digital fingerprinting for source code, ensuring traceability if IP is leaked or misused.

     
     

5. Clearly Define Workflow Policies:

   • Define tasking methods and authorities.

   • Implement pre-onboarding security training to educate developers about company policies, secure coding guidelines, and insider threat mitigation.

   • Define BYOD policy, work-etic relationships and social media restrictions.

   • Establish compliance requirements for SBOMs, particularly if the project is governed by regulations like NTIA, Executive Order 14028, or other supply chain security mandates.

     
     

6. Design Patterns:

Choosing the right technology stack for the mission to avoid misconfiguration errors and immature technology.

Educate on leveraging tools like AWS Cognito for social authentication rather than building personal tools - this practice enables secure, proven identity management practices, reducing risks associated with credential management, coding vulnerabilities [ Injections / buffer overflow / single point of failures].

Understand the overall architecture clearly - this may reduce the need for coding/protecting/scaling some services or the underlying yourself.

Use tools like OWASP Dependency-Track to manage and assess vulnerabilities in your technology stack.

Phase 1: Secure Development and Coding Environments

This phase must secure both local workstations and sandbox environments to prevent malicious code injections, unauthorized access, or accidental leaks.

1. Developer Workstation Security:

   • Domainless Environments: Developers should use pre-hardened, domainless environments hosted on secure platforms like AWS EC2 or Azure Virtual Machines with FIPS-compliant configurations.

   • Endpoint Detection and Response (EDR): Integrate EDR solutions like CrowdStrike Falcon or SentinelOne to monitor and protect developer machines from malware, exploits, or unauthorized changes.

   • Code Editor Hardening: Enforce secure IDE plugins and configurations to prevent misuse. Tools like JetBrains Security Plugin  can identify coding risks within editors.

   • Hardware: Consider using dedicated tenants to avoid possible data extraction from dual use hardware.

2. AAA Controls:

   • RBAC (Role-Based Access Control): Define strict role-based access permissions for sandbox environments, ensuring developers have the least privilege required.

   • ABAC (Attribute-Based Access Control): Add attribute-based rules such as device identity, geolocation, time-of-access, and IP whitelisting.

   • 2FA Enforcement: Combine 2FA with JIT (Just-in-Time) Access Controls for high-assurance authentication, minimizing exposure time.

   • Accounting : Collect audit traces and logs for detecting anomalies.

   • Tools: AWS IAM, HashiCorp Boundary, DataDog.

3. Secure Code Commit Signing:

   • Require developers to sign commits using GPG keys to ensure code integrity and authenticity.

4. Static Application Security Testing (SAST):

   • Automate SAST scans at every commit with tools like Semgrep, CodeQL, or Checkmarx.

   • Integrate SAST with IDEs and CI pipelines for real-time vulnerability feedback.

   • Enhance SAST findings with machine learning-based prioritization (e.g., ShiftLeft CORE).

5. Software Composition Analysis (SCA):

   • Identify and manage third-party dependencies using tools like Snyk, Mend (WhiteSource), or Dependabot.

   • Implement automated patch management workflows for libraries and dependencies.

   • Generate and maintain a Software Bill of Materials (SBOM) to ensure transparency and accountability in components.

   • Secure Secrets Management:

     • Prohibit hardcoding of secrets. Use dynamic secrets management tools like HashiCorp Vault, AWS Secrets Manager, or CyberArk Conjur.

     • Automate secrets rotation and access expiration.

     
     

     Phase 2: Build and Integration Security [CI]

     Securing the CI/CD pipelines ensures that malicious actors can’t exploit the build process or inject insecure code into production, a second layer of defense.

     1. Ephemeral Build Environments:

        • Use temporary, containerized environments to build artifacts (e.g., Kubernetes Jobs or GitHub Actions Runners).

        • Implement runtime isolation using tools like gVisor, Firecracker, or Kata Containers for enhanced sandboxing.

        • Integrity checks: Generate, validate, and update SBOMs automatically during the build. Make sure all artifacts are approved and signed.

          
          

     2. Cryptographic Signing for Artifacts:

        • Sign all build artifacts and container images using tools like Sigstore Cosign or Notary to ensure immutability and integrity.

        • Use Hardware-backed Signing Keys (e.g., YubiHSM or AWS KMS) to further protect signing processes.

     3. Policy as Code for Build Pipelines:

        • Automate security enforcement using tools like Open Policy Agent (OPA), Kyverno, or HashiCorp Sentinel.

        • Integrate CI/CD pipeline auditing tools like GitLab Compliance or Codefresh Policy Enforcement.

     4. Container Image Scanning and Hardening:

        • Use tools like Aqua Security, Anchore, or Trivy to scan container images for vulnerabilities.

        • Enforce best practices like minimal base images and signed, immutable images.

     
     
     
     

     1. Phase 3: Deployment Security [CD]

        Deployment security ensures that production systems remain resilient against emerging threats.

        1. Dynamic Application Security Testing (DAST):

   Phase 5: Operational Security and Governance

   1. RBAC and ABAC Implementation:

      • Combine RBAC for roles and ABAC for fine-grained access control (e.g., location, device, time). Tools: AWS IAM, Okta, or HashiCorp Boundary.

   2. Chaos Engineering for Security:

      • Simulate attacks or disruptions using tools like Gremlin or Chaos Monkey to validate system resilience under adverse conditions.

   3. Golden Images:

      • Use pre-hardened, secure OS images for consistency and compliance. Tools: Packer, AWS AMI, or VMware Templates.

   4. Insider Threat Mitigation:

      • Enforce Just-in-Time Access (JIT) and behavior analytics to reduce insider risks.

   5. Deployment Environment :

      Utilize tools such as AWS Control Tower which provides a single location to set up a well-architected, multi-account environment to govern your AWS workloads with rules for security.

   6. Probabilistic modeling:

      Conduct Monte Carlo Simulation - these quantified simulations can measure ongoing control effectiveness and optimize incident response plans in various random scenarios likes the real world. This technique enhances your ability to quantify risk, predict failure probabilities, and identify potential weaknesses in controls before they manifest in real-world scenarios.

   7. Seasonal Audits:

      Conduct Seasonal Audits following NIST frameworks in accordance to the objectives of the audit.
