Implementing DAST in SDLC: Optimal Timing and Integration
The rise of cyber threats makes it crucial to prioritize security in development, as neglect can lead to breaches and loss of trust. Rushed SDLC phases often leave hidden vulnerabilities, exposing applications and damaging reputations.
However, you can incorporate Dynamic Application Security Testing (DAST) into your SDLC to catch vulnerabilities early. This article covers DAST’s ideal timing and integration to fortify your applications against attacks.

Dynamic Application Security Testing (DAST) in Software Development Life Cycle (SDLC): When To Use it?
1. After the Initial Development Phase
DAST should be conducted in a staging environment, which closely mimics the production environment before the application goes live. This timing allows developers to identify and address vulnerabilities without significantly impacting the project timeline.
2. Before Major Releases
Conduct DAST tests before significant updates or feature releases. This practice ensures that new code does not introduce vulnerabilities that could compromise the entire application.
3. During Continuous Integration (CI) Pipelines
Integrate DAST into your Continuous Integration/Continuous Deployment (CI/CD) pipelines. CI/CD is a practice that automates the software development process, allowing for frequent code changes and deployments.Â
Running DAST regularly throughout development enables teams to catch vulnerabilities early and reduce remediation costs.

Dynamic Application Security Testing (DAST) in Software Development Life Cycle (SDLC): Where To Use it?
1. In Testing Environments
Conduct DAST in controlled testing environments that mimic production settings as closely as possible. This approach identifies vulnerabilities without exposing live data or systems to risk.
2. During Compliance Assessments
Incorporate DAST during compliance checks to ensure your application meets industry standards. Many regulatory frameworks mandate regular security testing, and DAST can help demonstrate compliance.
3. Alongside Other Testing Methods
You must combine DAST with Static Application Security Testing (SAST) and Interactive Application Security Testing (IAST). A layered security approach will provide comprehensive coverage and help you identify various vulnerabilities.
Benefits of DAST in the SDLC
- Real-World Attack Simulation: DAST identifies vulnerabilities in a running application, showing how an attacker might exploit weaknesses.
- Timely Remediation: Early identification of vulnerabilities allows developers to address issues before they escalate, minimizing potential damage.
- Enhanced Security Posture: Regular DAST implementation fosters a security culture within development teams, leading to more secure applications.
