Overview
Creating trustworthy software demands deliberate attention to three core security principles: availability, integrity, and confidentiality. The article outlines practical habits developers can adopt throughout the software lifecycle.
Building Phase Practices
Threat Modeling involves considering potential failures and appropriate responses. Coding Standards establish consistency but require careful balance between enforcement and practicality. Code Reviews leverage peer expertise, though effectiveness depends on reviewer skill. Code Quality Scans automate detection of poor practices. SAST (Static Analysis Software Testing) identifies vulnerabilities in source code quickly, though complexity and framework support present challenges. Various testing approaches—unit tests, integration tests, and end-to-end testing—validate functionality at different levels.
Testing Phase Activities
Vulnerability Testing highlights specific weaknesses without deep analysis. Penetration Testing simulates real attacks but requires significant resources. IAST (Interactive Application Security Testing) combines static and dynamic methods for detailed analysis. DAST (Dynamic Application Security Testing) finds runtime issues but may miss vulnerabilities not exposed during testing.
Deployment Phase Safeguards
Firewalls control network traffic. WAF (Web Application Firewall) filters HTTP traffic but can create false positives. RASP (Runtime Application Self-Protection) responds immediately to threats with potential performance trade-offs.
Conclusion
While comprehensive, these practices become manageable through incremental implementation and repetition, ultimately reducing long-term costs.
