This article is based on a source originally published at techbeacon.com in early 2017, covering concepts from the Gartner Research note DevSecOps: How to Seamlessly Integrate Security Into DevOps (September 2016).
The DevOps–Security Tension
DevOps has fundamentally changed how organizations build and ship software, collapsing release cycles from months to days or even hours. But as DevOps adoption accelerated, a persistent friction point emerged: information security. According to a Gartner note on DevSecOps from September 2016, roughly 80 percent of organizations surveyed felt that security policies and teams were preventing them from achieving the agility DevOps promises.
Development, operations, and security all share the same ultimate goal—business success—but they measure it differently. Developers track feature throughput and deployment frequency. Operations teams focus on uptime and mean time to recovery. Security professionals monitor vulnerability exposure, policy compliance, and audit readiness. Bridging those perspectives is the central challenge of DevSecOps.
Rather than waiting for security and compliance teams to find their own way into the DevOps workflow, development and operations teams should make the case proactively: integrating automated security controls into CI/CD pipelines benefits everyone. Below are five concrete ways to do it.
1. Remove Security as a Bottleneck
A foundational principle of DevOps—borrowed from lean manufacturing—is to identify and eliminate constraints that cause work to pile up. In many organizations, security reviews have become that constraint. The traditional model—build the application, hand it to security late in the cycle, wait for a vulnerability report, and then fix defects—is incompatible with continuous delivery.
When security functions as a gate rather than a guardrail, teams face pressure to ship anyway. The result is either a bottleneck that defeats the purpose of DevOps or, worse, security checks that get quietly bypassed because teams cannot afford the delay.
If security resists participating in the DevOps program, the temptation to circumvent security testing and policy reviews will become overwhelming.
The solution is to shift security left—integrating it earlier and continuously throughout the software delivery lifecycle, rather than treating it as a final checkpoint before release.
2. Use Automated Security Testing as a First-Class CI/CD Step
Manual security reviews that take days or weeks break the CI/CD feedback loop. The alternative is to apply the same small-batch philosophy to security testing that DevOps applies to feature development: run lightweight, automated checks on every commit or pull request, and reserve deeper analysis for scheduled scans or pre-release gates.
Application Security Testing (AST) tools—covering static analysis (SAST), dynamic analysis (DAST), and software composition analysis (SCA)—can be wired directly into your pipeline. Typical checks include:
- Known vulnerability patterns in custom code (e.g., SQL injection, cross-site scripting, buffer overflows).
- Dependency and library audits to flag prohibited or out-of-date third-party components.
- Secrets detection to catch hard-coded credentials, private keys, or API tokens committed to source control.
- Policy violations such as the use of deprecated cryptographic algorithms or non-compliant license types.
No automated tool is perfect, and AST cannot replace all human judgment. But embedding these tools in the pipeline means developers receive actionable feedback within minutes rather than days, making defects far cheaper to fix.
3. Build Security into the DevOps Collaboration Culture
DevOps is as much a cultural shift as a technical one. Security professionals can participate in that culture rather than standing apart from it. Practical steps include:
- Provide developer-facing security checklists that are actionable and context-specific, rather than lengthy policy documents.
- Offer security training to developers and operations staff, including the reasoning behind policies—not just the rules themselves.
- Publish secure coding guidelines covering common vulnerabilities so developers can prevent issues rather than fixing them after the fact.
- Help operations teams maintain secure configurations for containers, cloud environments, virtual machines, and physical infrastructure.
In return, security teams should embrace core DevOps practices: blameless postmortems that focus on systemic improvement rather than individual blame, Kanban-based work management for visibility into security tasks, and lean principles to reduce waste in security workflows. Embedding a security engineer in development squads (a “security champion” model) is one effective way to make this integration tangible.
4. Detect and Remediate Vulnerabilities Faster Using DevOps Tooling
One underappreciated security benefit of DevOps is traceability. Version-controlled infrastructure-as-code (IaC), immutable deployment artifacts, and detailed CI/CD audit logs make it significantly easier to pinpoint when and where a vulnerability was introduced—and to roll back or patch quickly.
Key practices that accelerate remediation include:
- Infrastructure as Code (IaC): Provisioning operating systems, directory services, and packages through code (e.g., Terraform, Ansible, Puppet) makes environments reproducible. A misconfigured server can be corrected in the IaC definition and redeployed consistently rather than patched manually on individual hosts.
- Small batch sizes: Smaller, more frequent deployments make it easier to isolate the change that introduced a problem.
- Shared observability: Operational monitoring data—logs, metrics, and anomaly alerts—can be shared with security teams as a feedback loop to surface unusual activity patterns that may indicate a breach or misconfiguration.
5. Treat Compliance as Code to Reduce Audit Overhead
Demonstrating compliance to auditors traditionally requires significant manual effort: collecting screenshots, exporting logs, and walking auditors through processes. DevOps automation changes this dynamic substantially.
Because DevOps pipelines are built on auditable, repeatable processes, the artifacts they produce—build logs, test results, deployment records, access control configurations—can serve as compliance evidence. Specific advantages include:
- Consistent process enforcement: Automation eliminates the configuration drift and manual errors that frequently produce compliance violations.
- Built-in segregation of duties: Access controls, approval gates, and role-based permissions can be enforced at the pipeline level, satisfying common audit requirements without manual oversight.
- Privileged access management (PAM): Identity and access controls can be codified and audited as part of the platform, rather than managed ad hoc.
- Predictable outcomes: An auditor can review the pipeline definition and test suite and trust that the described process reliably produces the described outcome—a much stronger posture than manual attestation.
DevSecOps: Security as a Shared Responsibility
The term DevSecOps captures the matured understanding that security cannot be bolted on at the end of a software delivery cycle—it must be a shared, continuous responsibility embedded throughout the pipeline. This is not about giving security teams a seat at the table as observers; it is about integrating security tooling, knowledge, and accountability into the same workflow that development and operations already use.
The five strategies above are not theoretical ideals. They represent a practical path: eliminate security as a release bottleneck, automate testing continuously, embed security expertise in development teams, use DevOps traceability to accelerate incident response, and leverage pipeline automation to reduce compliance burden. Organizations that follow this path can move faster and more securely—not as competing priorities, but as a unified outcome.
