Dry Development is the practice of avoiding repeated configuration by turning shared settings into reusable modules. In application security, it helps teams cut duplication, reduce maintenance work, and keep scan behavior consistent across many applications. The goal is simple operational reuse without losing control over how security rules are applied.
What Dry Development Means in Application Security
Dry Development is a reuse pattern for security configuration, not a security control by itself. It turns repeated settings into shared modules so teams can apply the same rule set across many applications without copying and pasting the same configuration into each one. In practice, it aims to reduce drift, preserve consistency, and make changes easier to manage.
Why Teams Use It
The main value of Dry Development is operational efficiency. When many applications need the same scan profile, policy baseline, or rule bundle, reusable modules avoid duplicate maintenance and make updates easier to roll out. That matters most where teams want consistent behaviour across environments without having to re-implement the same security logic in every repository or pipeline.
It also improves clarity of ownership. A central module can make it easier to see which settings are standard and which are exceptions, which is useful when security tooling is shared across multiple product teams. This is especially helpful when configuration sprawl would otherwise make it hard to tell whether two applications are being assessed with the same rules.
How It Reduces Configuration Drift
Repeated configuration is fragile because small manual edits accumulate over time. If one team changes a scan exclusion, timeout, or rule threshold in its own copy, the organisation can end up with different security behaviour that is hard to notice. Dry Development limits that drift by concentrating the reusable logic in one place and making downstream consumers reference it rather than recreate it.
That does not remove the need for careful change control. A shared module can spread a bad decision quickly if it is updated without review, so the benefit comes from disciplined reuse, not from reuse alone. The pattern works best when the module boundary is clear and the teams consuming it understand which settings are intentionally shared and which are meant to stay local.
Where It Fits in Secure Engineering
Dry Development fits naturally in secure engineering and security automation because it supports repeatable policy application. The same idea is useful whenever teams need a stable baseline for application security scans, build rules, or environment-specific configuration that should not be reinvented every time. As a software-delivery practice, it aligns with the broader goal of making security behaviour more predictable across the application estate.
It is most effective when paired with versioned modules, reviewable change ownership, and a clear separation between shared defaults and application-specific overrides. When those boundaries are weak, the pattern can become opaque, and the team may lose sight of how a given application actually inherits its security posture.
When Dry Development Becomes a Problem
Dry Development can fail if the shared module becomes too broad, too opaque, or too tightly coupled to one team’s assumptions. In that case, reuse starts to conceal variation instead of removing it, and teams may no longer know which applications depend on which configuration choices. The result is less visibility, not more.
It can also create hidden dependency risk if many applications rely on one module that is changed without coordination. That is why the pattern is best treated as a governance technique for configuration reuse, not as a substitute for local validation or review of the applications that consume it.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP ASVS, OWASP SAMM, NIST SP 800-53 Rev 5 and CIS Controls v8 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP ASVS | V13 — Configuration | Dry Development standardises reusable security configuration across applications. |
| Recommendation — Centralise shared security settings so application teams apply consistent configuration through reusable modules. | ||
| OWASP SAMM | GOVERNANCE — Governance | Dry Development is a software delivery practice that needs ownership and controlled reuse. |
| Recommendation — Define ownership and review for shared security modules used across the delivery lifecycle. | ||
| NIST SP 800-53 Rev 5 | CM-6 — Configuration Settings | Shared modules formalise approved baseline settings and reduce configuration drift. |
| Recommendation — Establish approved configuration baselines and manage changes through controlled updates to shared modules. | ||
| CIS Controls v8 | CIS-4 — Secure Configuration of Enterprise Assets and Software | The pattern supports repeatable secure configuration across multiple applications and environments. |
| Recommendation — Use standard secure configuration templates to keep application settings consistent and maintainable. | ||
Practitioner Guidance
Governance implication: Treat shared security modules as versioned assets with clear ownership, documented defaults, and explicit override rules. That keeps reuse predictable and prevents teams from silently diverging from the intended baseline.
What to watch for: Watch for module sprawl, undocumented overrides, and consumers that inherit settings they do not understand. Those are the signs that reuse is becoming a source of ambiguity rather than a source of consistency.
