Security into the SDLC to prevent security problems
As organizations work to build security into the SDLC to prevent security problems before they begin, what are some of the software approaches they use? Also, discuss a few Infosec management tools.

Building Security into the SDLC: Software Approaches and Infosec Management Tools
As organizations strive to shift from reactive security measures to proactive ones, integrating security throughout the SDLC (Software Development Life Cycle) becomes paramount. This involves incorporating security considerations at every stage, from initial design to deployment and beyond. Here are some software approaches and Infosec management tools used to achieve this:
Software Approaches:
-
Static Application Security Testing (SAST): Analyzes source code for vulnerabilities before compilation. It detects potential issues like SQL injection, cross-site scripting (XSS), and buffer overflows.
-
Dynamic Application Security Testing (DAST): Tests running applications for vulnerabilities by simulating real-world attacks. This helps identify issues that might not be apparent during static analysis.
-
Interactive Application Security Testing (IAST): Combines SAST and DAST by instrumenting code and performing real-time analysis during development. It provides more accurate and actionable insights.
-
Security by Design: Embeds security considerations into the design and architecture of applications from the very beginning. This involves secure coding practices, secure libraries, and authentication/authorization mechanisms.
