Security

Secure software development is a practice that integrates security considerations into every phase of the software development lifecycle (SDLC). The goal is to build resilient and robust software that can withstand attacks, protect user data, and maintain the integrity of the systems it runs on. This involves a shift from a reactive "patch-on-breach" model to a proactive, "secure-by-design" approach. By thinking about potential threats and building defenses from the very beginning, we can reduce vulnerabilities, mitigate risks, and create more trustworthy products. This guide provides an overview of various security domains, from organizational policies to specific hardening techniques for different platforms and technologies.
