What is DevSecOps?
DevSecOps (Development, Security, Operations) is the practice of integrating security controls into every stage of the software development lifecycle rather than performing security checks as a separate gate at the end. The shift: instead of a security team reviewing code once a quarter or before a major release, security controls run automatically in the CI/CD pipeline on every code change. SAST scans every pull request for code vulnerabilities. Dependency scanning identifies newly disclosed CVEs in third-party packages. Container image scanning blocks deployment of images with critical vulnerabilities. Secrets detection prevents API keys and credentials from entering the codebase. The result: security issues are caught at the cheapest possible moment (in the developer's pull request, not in a post-production audit) and security is a shared engineering responsibility rather than a separate team's bottleneck.
What is SAST vs DAST?
SAST (Static Application Security Testing) analyses source code without executing it looking for security vulnerabilities in the code itself (SQL injection patterns, insecure direct object references, hardcoded credentials, dangerous API usage). SAST runs at pull request time before the code is deployed. DAST (Dynamic Application Security Testing) tests the running application from the outside sending malicious inputs and observing the responses, the same way an attacker would probe the live application. DAST runs against a staging environment. Both are necessary: SAST catches code-level vulnerabilities early and cheaply; DAST catches configuration vulnerabilities, business logic flaws, and runtime security issues that SAST cannot detect because they only manifest in the running application.
What is a Software Bill of Materials (SBOM) and why does enterprise sales require one?
An SBOM (Software Bill of Materials) is a complete inventory of every software component in an application every library, package, and dependency, with version numbers and licence information. It is analogous to an ingredients list for software. Enterprise and government buyers require SBOMs because: a) US Executive Order 14028 (May 2021) mandates that software sold to the US federal government must include an SBOM, b) enterprise procurement security teams use SBOMs to assess supply chain risk identifying whether your application contains a vulnerable version of a widely exploited library (e.g., Log4j), and c) SBOM enables continuous vulnerability monitoring as new CVEs are disclosed, the buyer can check whether their vendor's software is affected. ClickMasters generates SBOMs using Syft (producing SPDX or CycloneDX format) as part of the container build pipeline, signs them with cosign, and stores them in ECR alongside the container image.
What is Policy-as-Code and how does it prevent insecure infrastructure?
Policy-as-Code means encoding security and compliance rules as machine-readable policies that are automatically enforced during infrastructure changes rather than relying on manual security reviews of Terraform plans. Example policies: "S3 buckets must not have public access enabled", "RDS instances must have encryption at rest", "IAM roles must not use wildcard (*) actions in production", "Kubernetes Pods must not run as root". These policies are written in OPA (Open Policy Agent) Rego language or as Checkov/tfsec rules, and the CI/CD pipeline runs them against every Terraform plan before applying. If a planned infrastructure change violates a policy, the pipeline blocks the change and shows which policy was violated and how to fix it. This prevents security misconfigurations from reaching production the most common source of cloud security breaches is not sophisticated attacks but misconfigured infrastructure.
