Tips for Rethinking Software Security Practices

Most product founders (or aspiring founders) think cybersecurity is something that can be added on as we go. In 2024, 68 % of breaches involved a non‑malicious human element, like misconfigurations or coding oversights. Security isn’t a checkbox at launch; it’s a mindset woven into every sprint, every pull request, every architectural decision. Here’s a playbook we, at GrayCyan, have developed: 1️⃣. Threat Model Upfront Before you write a single line of code, map out your attack surface. What data are you storing? Who could target it, and how? A lightweight threat model (even a few whiteboard sketches) helps you prioritize controls around your riskiest assets. 2️⃣. Secure Design Patterns Adopt proven patterns—like input validation, output encoding, and the principle of least privilege—right in your prototypes. Whether it’s microservices or monolithic apps, enforcing separation of concerns and privilege boundaries early means fewer surprises down the road. 3️⃣. Shift‑Left Testing Integrate static analysis (SAST), dependency scanning, and secret‑detection tools into your CI/CD pipeline. Automate these checks so that every pull request tells you if you’ve introduced a risky dependency or an insecure configuration—before it ever reaches production. 4️⃣. Continuous Code Reviews Encourage a culture of peer review focused on security. Build short checklists (e.g., avoid hard‑coded credentials, enforce secure defaults) and run them in review sessions. Rotate reviewers so everyone gets exposure to security pitfalls across the codebase. 5️⃣. Dynamic & Pen‑Test Cycles Complement static checks with dynamic application security testing (DAST) and periodic penetration tests. Even a quarterly or biannual pen‑test will surface issues you can’t catch with automated scans—like business‑logic flaws or subtle authentication gaps. 6️⃣. Educate & Empower Your Team Run regular “lunch‑and‑learn” workshops on topics like OWASP Top 10, secure cloud configurations, or incident response drills. When developers think like attackers, they write more resilient code—and spot risks early. 7️⃣. Plan for the Inevitable No system is 100 % immune. Build an incident response plan, practice it with tabletop exercises, and establish clear escalation paths. That way, when something does go wrong, you move from panic to precision—minimizing impact and restoring trust. At GrayCyan, we partner with founders (and upcoming founders that have amazing product ideas) to embed these practices as we build apps.

Shift left is NOT dead! It’s just become misunderstood for some reason. Let’s clear it up: Shift left in cybersecurity simply means adding security habits earlier in the software development lifecycle (SDLC). It means implementing proactive security habits closer to design and coding, rather than ONLY reacting once software is already in production. But here’s the key: To shift left effectively, you should first "start right". Start Right: Build visibility, monitoring, and resilience in production - Monitor for real-world threats and attacks - Respond to and fix actual exploitable production vulnerabilities (found via pentests and bug bounty findings) - Track the cost and impact of security incidents Then, use root cause analysis to connect these incidents to upstream opportunities for prevention, so you can make the case for... Shift Left: Move prevention and awareness earlier in the lifecycle - Conduct architecture reviews and regular threat modeling - Define security requirements and apply secure coding practices - Deliver secure code training - Implement pre-production scanning (SAST, SCA, etc.) Once both the right-side and left-side controls are in place, you have successfully shifted "everywhere" - the ultimate goal! But let’s be clear: “Shift everywhere” does NOT mean pushing the security responsibilities onto the developers. It means building effective security controls into the SDLC itself, with well defined shared responsibilities across: - Developers - Security - Product and Project Managers - Engineering leaders …and anyone else involved in shipping software This all will require CHANGE to your organization's habits and culture, which takes time, and a whole lot of patience. You’ll need allies. You’ll need security champions. Your security team can’t do this alone. Start right → Shift left → Shift everywhere! #applicationsecurity #productsecurity #softwaresecurity #securitychampions #securityculture #proactivesecurity #devsecops #developerexperience #shiftleft #shifteverywhere #sdlc

How proactive is your organization in integrating security from the ground up? Integrating security at every development stage is essential. Secure by Design (SbD) means building security into products from the beginning to reduce vulnerabilities and risks. Fundamental principles to understand... 1) Early Integration: Embed security throughout the Software Development Life Cycle (SDLC) using frameworks like NIST's SSDF. 2) Automation: Utilize CI/CD pipelines to enforce secure configurations automatically. 3) Layered Security: Implement multiple security measures so if one fails, others protect the system. 4) Secure AI Applications: Integrate security into AI and ML pipelines to protect sensitive data. 5) Proactive Threat Modeling: Identify and address potential threats during the design phase. How to get started -Assess Current Practices: Identify where security isn't integrated. For example, assess your build process today. -Educate Your Team: Train staff on SbD principles. There is no need for expensive training; use YouTube. -Implement Frameworks: Use established security frameworks and automate processes. Don’t try to create your own; pick a framework and run with it. -Continuous Improvement: Review and update security measures regularly. This is not a once-and-done process. Consider reviewing at least yearly. How can adopting a Secure by Design approach benefit your organization?
