Duration 2 days – 14 hours

 

Overview

 

This Web Application Security with SDL training equips participants with the essential knowledge and practical skills to build and maintain secure web applications by integrating security into every phase of the Secure Development Lifecycle (SDL).

 

Participants will learn how common web vulnerabilities happen (based on modern industry threats), how to prevent them through secure coding practices, and how to apply SDL controls such as threat modeling, secure design reviews, security testing (SAST/DAST), code review, and release security gates. The course combines hands-on demonstrations, real-world scenarios, and practical checklists to help teams implement security-by-design and reduce application security risks.

 

Objectives

 

• Explain web application security risks and why SDL is critical
• Identify common web vulnerabilities and attack paths
• Apply secure coding and secure design principles for web apps
• Conduct basic threat modeling and security requirement definition
• Implement SDL checkpoints (planning → build → test → release → operations)
• Use secure code review practices and vulnerability prevention techniques
• Understand security testing approaches (SAST, DAST, dependency scanning)
• Establish practical security controls for continuous improvement and compliance

 

Target Audience

 

• Web Developers (Front-End / Back-End / Full Stack)
• Software Engineers and Technical Leads
• QA / Test Engineers (especially Security Testing roles)
• DevOps / DevSecOps Engineers
• Application Support / Production Support Teams
• Software Architects
• IT Security / InfoSec Professionals involved in application security
• Project Managers / Delivery Managers managing software releases

 

Prerequisites 

• Basic knowledge of web application concepts (HTTP/HTTPS, APIs, cookies, sessions)

• Familiarity with modern web development practices (any language/framework)

• Basic understanding of SDLC is helpful but not required

• Laptop recommended for hands-on demos/tools (optional)

 

Course Outline 

 

Day 1 — Web Application Security Fundamentals + Core Vulnerabilities

 

Module 1: Introduction to Web Application Security

 

• Why web apps are prime targets
• Security goals: Confidentiality, Integrity, Availability
• Common attack surfaces (web, API, auth, data, 3rd party components)
• Security mindset: “Shift Left” + security-by-design

 

Module 2: Secure Development Lifecycle (SDL) Overview

 

• What is SDL and how it reduces security risks
• SDL phases and security gates
• Roles & responsibilities (Dev, QA, Security, Product, Ops)
• Defining “Done”: security acceptance criteria

 

Module 3: Top Web Vulnerabilities (Modern and Practical)

 

• Injection (SQL/NoSQL, command injection)
• Cross-Site Scripting (XSS) and input/output encoding
• Broken authentication & session management

  Activity: Vulnerability recognition workshop (real scenarios)

 

Module 4: Secure Coding Foundations

 

• Input validation (server-side vs client-side)
• Output encoding and safe rendering
• Password storage best practices (hashing + salt)
• Secure logging practices (avoid sensitive leakage)
