Achieving Secure Application Modernization with DevSecOps

This document is a guide that outlines the process of modernizing federal legacy systems through the integration of DevSecOps methodologies. It emphasizes the importance of updating outdated systems to reduce technical debt and enhance cybersecurity. The guide explains how federal agencies can transition from traditional waterfall development processes to more agile DevOps practices, ultimately leading to DevSecOps. It details the benefits of embedding security throughout the software development lifecycle (SDLC), ensuring that security vulnerabilities are identified and addressed early in the development process. The guide also presents a step-by-step approach for agency leaders to assess their current operations, prioritize programs based on impact and risk, and establish a culture that integrates security into application development. By adopting DevSecOps, agencies can achieve a balance between speed and security, thereby improving their operational efficiency and safeguarding critical systems against cyber threats.
