: One of the original industry models for secure coding.
: Operating under the assumption that threats exist both inside and outside the network, requiring continuous verification of every request. Phases of the Secure Development Lifecycle (SDL) security-driven software development pdf download
Security-driven software development, often integrated into the lifecycle, shifts security from a final "checkpoint" to a core requirement throughout the entire development process. Instead of treating security as a perimeter defense, this methodology builds it into the application's architecture and code. Core Principles of Security-Driven Development : One of the original industry models for secure coding
: Conduct Dynamic Application Security Testing (DAST) on the running application and perform manual penetration testing to find complex logic flaws. Instead of treating security as a perimeter defense,
: Establish secure architectural patterns. Choose frameworks that have built-in protections against common vulnerabilities like SQL injection or Cross-Site Scripting (XSS).
: Security testing (vulnerability scanning, static analysis) begins as soon as the first line of code is written, rather than during the testing or deployment phase.
