Question 1

What is DevSecOps and how does it differ from traditional security?

Accepted Answer

DevSecOps is the practice of integrating security controls, testing, and governance directly into the software development lifecycle (SDLC) rather than applying them at the end of a release cycle. Traditional application security relies on periodic penetration tests and security reviews that catch issues late, when they are expensive and time-consuming to fix. DevSecOps embeds automated security scanning into every CI/CD pipeline run - static analysis, dependency scanning, container image scanning, and dynamic testing - so vulnerabilities are detected when the code is written rather than weeks before a release. The shift-left model reduces both the cost of remediation and the time between vulnerability discovery and resolution.

Question 2

What SAST tools do you integrate into CI/CD pipelines?

Accepted Answer

We integrate SAST tools based on the technology stack and regulatory requirements of the engagement. For most enterprise environments, we implement SonarQube for multi-language static analysis with quality gate enforcement, Checkmarx SAST for deep dataflow analysis in highly regulated industries, and Semgrep for custom rule authoring aligned to organisation-specific security standards. GitHub Advanced Security or GitLab SAST are added for repositories on those platforms. All SAST tools are configured with scan thresholds that block pipeline promotion when high or critical severity findings are introduced, ensuring only reviewed and accepted risks enter production.

Question 3

How do you implement DAST in a CI/CD pipeline?

Accepted Answer

Dynamic Application Security Testing (DAST) scans running applications for vulnerabilities such as injection flaws, authentication weaknesses, and sensitive data exposure. We integrate OWASP ZAP in baseline scan mode into CI/CD pipelines targeting deployed staging environments, with full active scan mode run on a scheduled basis against pre-production. For API-heavy applications, we configure ZAP with OpenAPI specifications to ensure comprehensive coverage of all endpoints. DAST findings are correlated with SAST results in a unified vulnerability management platform (Defect Dojo or a SIEM) to provide a complete picture of application security posture.

Question 4

What is software composition analysis (SCA) and why does it matter?

Accepted Answer

Software Composition Analysis identifies open-source dependencies in your applications and alerts when they contain known vulnerabilities (CVEs) or use restrictive licences that create legal risk. The Log4Shell vulnerability demonstrated how a single widely-used open-source library can expose thousands of enterprise applications simultaneously. We implement SCA using OWASP Dependency-Check, Snyk Open Source, or GitHub Dependabot, configured to break builds on high-severity CVEs with no available patch and to generate software bills of materials (SBOMs) in CycloneDX or SPDX format for supply chain transparency. Licence compliance policies are enforced to prevent GPL or AGPL components from entering proprietary software.

Question 5

How do you perform container image scanning in DevSecOps pipelines?

Accepted Answer

Container image scanning is implemented as a mandatory gate in the CI/CD pipeline immediately after the image build step. We use Trivy for its comprehensive vulnerability database coverage across OS packages and application dependencies, and Grype as a complementary scanner for cross-validation of critical findings. Images that fail vulnerability thresholds are blocked from being pushed to production registries. We also implement Cosign image signing so that Kubernetes admission controllers can verify image provenance at deployment time. Base image freshness is enforced through automated dependency update pull requests for Dockerfile base image versions.

Question 6

What is policy-as-code and how do you implement it?

Accepted Answer

Policy-as-code encodes security and compliance rules as machine-readable policies that are automatically evaluated against infrastructure definitions and Kubernetes configurations. We implement Open Policy Agent (OPA) with Conftest for Terraform plan and Kubernetes manifest validation in CI/CD pipelines, and Kyverno as an admission controller that enforces policies on resources being applied to the Kubernetes cluster. Policies cover required labels and annotations, container security contexts (non-root, read-only filesystem), prohibited capabilities, mandatory resource limits, and network policy requirements. Policy libraries are version-controlled alongside application code and reviewed through the same peer review process.

Question 7

How do you manage secrets in a DevSecOps context?

Accepted Answer

Secrets management is one of the highest-impact DevSecOps controls. We implement HashiCorp Vault as the central secrets management platform, with cloud-native secrets managers (AWS Secrets Manager, Azure Key Vault, GCP Secret Manager) for cloud-specific workloads. CI/CD pipelines authenticate to Vault using short-lived OIDC tokens rather than static credentials, eliminating the risk of long-lived secret leakage. The External Secrets Operator synchronises secrets from Vault into Kubernetes Secrets at runtime. We also implement Gitleaks or TruffleHog scanning in pre-commit hooks and CI pipelines to detect any secrets accidentally committed to source control.

Question 8

How do you handle runtime security for containerised workloads?

Accepted Answer

Runtime security for containers uses Falco, an open-source runtime security tool that detects anomalous behaviour based on system call patterns. Falco rules are configured to alert on suspicious activities such as shell spawning in containers, unexpected network connections, sensitive file access, and privilege escalation attempts. Alerts are routed to the SIEM for correlation with other security events. For Kubernetes workloads, we also configure seccomp profiles, AppArmor or SELinux profiles, and Pod Security Standards (PSS) to constrain the system calls and capabilities available to containers at the OS level.

Question 9

What compliance frameworks does your DevSecOps implementation support?

Accepted Answer

Our DevSecOps pipeline implementations generate evidence supporting SOC 2 Type II (CC6.6, CC6.7, CC8.1), ISO 27001 (A.12.6, A.14.2), PCI DSS (Requirement 6), and NIST CSFD (PR.IP-1, DE.CM-8). Evidence packages include SAST and DAST scan reports, SCA vulnerability management records, image signing attestations, and policy evaluation logs. For organisations undergoing certification audits, we produce evidence reports in auditor-friendly formats and support QSA or ISO certification body reviews. DevSecOps pipeline configurations are themselves version-controlled and subject to change management controls.

Question 10

How do you integrate DevSecOps tooling with existing vulnerability management workflows?

Accepted Answer

DevSecOps scanning generates large volumes of findings that must be triaged, deduplicated, and tracked to resolution. We implement Defect Dojo as a centralised vulnerability management platform that ingests findings from all scanners (SAST, DAST, SCA, container scanning) and deduplicates across tools. Findings are automatically assigned to product teams based on repository ownership, prioritised by CVSS score and business context, and tracked to resolution with SLA-based escalation. Integration with Jira ensures security findings appear in the same backlog as feature work, preventing them from being deprioritised.

Question 11

How do you approach supply chain security in DevSecOps?

Accepted Answer

Supply chain security covers the integrity of code, dependencies, build systems, and deployment artefacts. We implement SLSA (Supply-chain Levels for Software Artefacts) framework controls: verified source control (signed commits), hermetic builds in isolated CI runners, provenance attestation using Sigstore and Cosign, and policy-based deployment gates that verify provenance before allowing images into production. SBOM generation in CycloneDX format is automated for every release, enabling rapid impact assessment when a new CVE affecting a common dependency is disclosed.

Question 12

How do you handle security findings without blocking developer productivity?

Accepted Answer

Balancing security rigour with developer velocity requires careful threshold configuration and developer experience design. We implement a tiered finding management approach: critical and high-severity findings with known exploits block the pipeline immediately; other high-severity findings create Jira tickets with a 5-day SLA and trigger notifications but do not block the build; medium and low-severity findings are aggregated into weekly security reports. False positive management is addressed through regular scan configuration reviews. Developer-facing tooling - IDE plugins for SonarQube and Snyk - surfaces findings during development before code reaches the CI pipeline.

Question 13

What is your approach to securing infrastructure as code?

Accepted Answer

Infrastructure as code security scanning uses Checkov, KICS, or tfsec to evaluate Terraform and CloudFormation templates for security misconfigurations before they are applied. Policies cover open security groups, unencrypted storage, public S3 buckets, missing logging, and IAM overpermissioning. Checkov is integrated into CI pipelines as a blocking gate, and results are published to the central vulnerability management platform. Drift detection between Terraform state and actual cloud configurations is monitored using Driftctl, alerting when out-of-band changes introduce security gaps.

Question 14

How do you train development teams in DevSecOps practices?

Accepted Answer

Developer security training is integrated into the DevSecOps transformation through role-specific learning paths. Developers receive training on the OWASP Top 10, secure coding practices in their primary language, and how to interpret and remediate SAST findings using interactive exercises. Security champions are identified within each product team and receive additional training on threat modelling, secure design review, and security testing methodology. We run regular "bug bash" sessions where development and security teams review findings together, building shared understanding of vulnerability patterns specific to the codebase.

Question 15

How do you measure DevSecOps programme maturity?

Accepted Answer

DevSecOps maturity is measured across five dimensions: pipeline coverage (percentage of repositories with security scanning), mean time to remediate (by severity tier), vulnerability density (findings per 1,000 lines of code), policy compliance rate (percentage of deployments passing all policy gates), and security incident rate (production security incidents attributable to code or configuration vulnerabilities). We produce a monthly DevSecOps scorecard covering these metrics and use a maturity model (Initial, Developing, Defined, Managed, Optimising) to track programme-level improvement over time.

Question 16

What does a DevSecOps engagement typically include?

Accepted Answer

A DevSecOps engagement begins with a pipeline security assessment covering current toolchain coverage, findings management process, and developer experience. This produces a prioritised roadmap for tool integration and process improvement. Implementation covers SAST, SCA, container scanning, secrets detection, DAST, and policy-as-code integration into CI/CD pipelines, followed by a vulnerability management platform setup and developer training programme. Ongoing managed DevSecOps services are available, covering scanner configuration management, policy library maintenance, monthly findings review, and developer security coaching.
