Duration: 3 Days
Secure .Net Coding is a hands-on, lab-intensive .Net security, code-level training course that teaches you the best practices for designing, implementing, and deploying secure programs in .Net. This course explores well beyond basic programming skills, teaching developers sound processes and practices to apply to the entire software development lifecycle. You will take an application from requirements through to implementation, analyzing and testing for software vulnerabilities. Perhaps just as significantly, you will learn about current, real examples that illustrate the potential consequences of not following these best practices.
The course provides a solid foundation in basic terminology and concepts, extended and built upon throughout the engagement. You will examine various recognized attacks against web applications. Processes and best practices are discussed and illustrated through both discussions and group activities. This workshop is approximately 50% dynamic lab exercises and 50% lecture, providing in-depth, code-level labs.
The second portion of the course steps through a series of vulnerabilities illustrating in very real terms the right way to implement secure .Net applications. The last portion of the course examines several design patterns that can be used to facilitate better application architecture, design, implementation, and deployment.
A key component to our Best Defense IT Security Training Series, this workshop is a companion course with several developer-oriented courses and seminars. Although this edition of the course is .Net-specific, it may also be presented using Java or other programming languages.
