Secure Software Development Lifecycle

Security from the first line to the last deploy. SSDLC implementation aligned to OWASP SAMM and BSIMM — threat modeling, secure coding, SAST/DAST/SCA, and pre-deployment testing.

Security embedded at every SDLC phase — from threat modeling and security requirements through SAST/SCA integration, DAST, and pre-deployment penetration testing.

REQUIREMENTS & DESIGN

Security Requirements & Threat Modeling

Embedding security at the earliest phase of the SDLC — defining security requirements tailored to your business context, conducting threat modeling (STRIDE, PASTA) to identify design-phase risks, and validating architectures against threat models before a single line of code is written.

  • Security requirements definition and ABAC design
  • STRIDE and PASTA threat modeling facilitation
  • Architecture security review and design validation
  • Security user story integration into Agile backlog
IMPLEMENTATION

Secure Coding Standards & Automated Testing

Integrating security into the build phase — secure coding standards for your language stack, SAST integration into your IDE and CI pipeline, SCA/dependency scanning, and developer security training focused on the vulnerability patterns most common in your codebase.

  • Secure coding standards (OWASP Secure Coding Practices)
  • SAST integration (Snyk, SonarQube, Semgrep)
  • SCA and dependency vulnerability scanning
  • Developer security training (OWASP Top 10)
TESTING & DEPLOYMENT

Security Testing & Pre-Deployment Review

Comprehensive security testing before production — DAST against staging environments, pre-deployment penetration testing and security acceptance testing, and final security sign-off review ensuring all critical and high findings are remediated before the release gate.

  • DAST and interactive security testing (IAST)
  • Pre-deployment penetration testing
  • Security acceptance testing and sign-off
  • Post-deployment configuration review
The SSDLC Business Case

Fix It at Design — or Pay 30× the Cost in Production

The cost of fixing a security vulnerability is not fixed — it scales dramatically with how late in the development process it is found. A design-phase threat model that identifies a missing authentication control costs hours of architecture discussion. The same control missing in production costs emergency patching, incident response, and potential breach notification.

SSDLC gives your development team the tools to find and fix vulnerabilities at the cheapest possible point — in the developer's IDE, in the pull request, and in staging — not in a security incident.

Security vulnerabilities found in the requirements phase cost 1× to fix. The same vulnerability found in production costs 30×. SSDLC automation pays for itself in the first critical vulnerability caught at the code commit stage rather than in a production incident.
OWASP research shows that 90% of web application vulnerabilities are in the OWASP Top 10 — categories that are well understood, preventable with secure coding practices, and detectable with SAST tools. Most organizations are still shipping these vulnerabilities to production.
The average time for a vulnerability discovered in a bug bounty or security report to be exploited in the wild is under 24 hours. Organizations without pre-deployment security testing have a shrinking window between vulnerability introduction and exploitation.

OWASP Top 10

90% of web application vulnerabilities fall into well-understood, preventable OWASP Top 10 categories.

Design Phase Cost

Fixing a vulnerability at the design phase costs 1× — the cheapest point in the entire SDLC.

Production Cost

The same vulnerability in production costs 30× in emergency patching, incident response, and reputation damage.

Exploit Window

Average time from vulnerability disclosure to active exploitation in the wild has dropped below 24 hours.

Our Process

5-Phase SSDLC Implementation

From OWASP SAMM maturity assessment through threat modeling integration, SAST/SCA/DAST setup, and continuous improvement metrics.

01

SDLC Maturity Assessment

Assessing your current software development security maturity against OWASP SAMM or BSIMM — identifying which security practices are in place, which are missing, and which present the highest risk. The output is a roadmap of SSDLC improvements prioritized by risk reduction impact.

02

Security Requirements & Threat Modeling Integration

Working with your product and engineering teams to integrate security requirements definition into the planning phase and threat modeling into the design phase — embedding these as standard process steps in your development workflow, not optional extras.

03

Secure Coding Standards & SAST/SCA Integration

Defining secure coding standards for your technology stack and integrating SAST and SCA tools into your IDE (for developer feedback) and CI pipeline (for quality gate enforcement). We tune tools for your codebase to minimize false positives while maintaining genuine vulnerability detection.

04

Security Testing Automation

Integrating DAST into your staging pipeline and establishing the pre-deployment penetration testing cadence — determining which releases require full penetration testing versus automated security acceptance testing, and configuring the tooling to support both.

05

Security Metrics & Continuous Improvement

Establishing SSDLC KPIs — vulnerability density per release, mean-time-to-remediation, security gate pass rates — and creating the reporting framework to track maturity improvement over time against the OWASP SAMM or BSIMM benchmark established in phase 1.

Coverage

Full SDLC Security Coverage

From threat modeling and security requirements through SAST, SCA, DAST, penetration testing, and SAMM maturity metrics.

Threat Modeling

Structured threat modeling (STRIDE, PASTA, LINDDUN) facilitated for new features and major architectural changes — identifying threats and countermeasures at the design phase before implementation cost is committed.

Security Requirements

Translating business security objectives into specific, testable security requirements — functional security requirements (authentication, authorization, encryption) and non-functional requirements (logging, rate limiting, input validation).

SAST / Code Review

Static Analysis Security Testing (SAST) integrated into IDE and CI pipeline — catching injection flaws, authentication weaknesses, cryptographic misuse, and insecure data handling before code is merged.

SCA & Dependency Scanning

Software Composition Analysis identifying vulnerable third-party libraries and transitive dependencies — with automated dependency update PRs (Dependabot, Renovate) and license compliance checking.

DAST & Penetration Testing

Dynamic Application Security Testing against staging environments and pre-deployment penetration testing for major releases — finding runtime vulnerabilities not visible to static analysis.

SAMM / BSIMM Metrics

SSDLC maturity measurement against OWASP SAMM or BSIMM benchmarks — quantifying security practice maturity across governance, design, implementation, and verification domains.

Why Adayptus

SSDLC That Developers Embrace — Not Resist

Security programs that developers see as blockers get bypassed. We design SSDLC implementations that fit the way your teams actually work — and track the risk reduction they produce.

Maturity-Based Roadmap

We baseline your SSDLC maturity against OWASP SAMM before recommending improvements — so every change we make is targeted at the highest-risk gaps in your specific development process, not a generic checklist.

Developer-Centric Design

SSDLC programs fail when they create bottlenecks that slow delivery. We design security activities that integrate into Agile sprints — threat modeling in sprint 0, SAST in PR review, DAST in staging — without adding hand-off delays.

Stack-Specific Guidance

Secure coding standards and tool configurations are tailored to your actual technology stack — Java Spring Boot, Node.js, Python Django, .NET, React — not generic guidance that doesn't apply to your codebase.

Measurable Risk Reduction

We define SSDLC KPIs at the start — vulnerability density per release, MTTD and MTTR — and track them monthly. You get evidence that the program is working, not just activity reports.
