Applications built on .NET platforms must be resilient, secure, and threat-aware. This course develops participants’ capabilities to embed security controls within the .NET development lifecycle. Through practical exercises, they will assess risks, harden code, and ensure compliance with application security standards.
Learning Outcomes:
Understand .NET platform-specific security challenges
Implement secure coding practices within .NET applications
Conduct risk analysis and threat modelling
Apply defensive coding techniques and input validation
Develop secure authentication and error handling mechanisms
Key Topics:
.NET application architecture and security principles
Common coding vulnerabilities and mitigations
Access control and cryptography in .NET
Threat modelling and code review processes
Secure database handling and configuration management
Exam Details
This course is designed to build participants’ understanding of key concepts and development practices aligned with the Certified Application Security Engineer (CASE) certification.
The certification evaluates participants on secure application development across the Software Development Lifecycle (SDLC), including requirements gathering, secure design, coding, testing, and post-deployment protection.
CASE is designed for software engineers, analysts, and testers responsible for developing secure, robust applications. The training prepares participants with both practical and theoretical knowledge to address real-world security risks in application environments.
To maximise success, participants are strongly encouraged to complement the course with additional self-study, revision of course materials, and dedicated practice before attempting the exam.
