Back to course catalogThe secure coding landscape
Description
The course introduces some common security concepts, gives an overview about the nature of the vulnerabilities regardless of the used programming languages and platforms, and explains how to handle the risks that apply regarding software security in the various phases of the software development lifecycle. Without going deeply into technical details, it highlights some of the most interesting and most aching vulnerabilities in various software development technologies, and presents the challenges of security testing, along with some techniques and tools that one can apply to find any existing problems in their code.
Participants attending this course will
- Understand basic concepts of security, IT security and secure coding
- Understand Web vulnerabilities both on server and client side
- Realize the severe consequences of unsecure buffer handling
- Be informated about some recent vulnerabilities in development environments and frameworks
- Learn about typical coding mistakes and how to avoid them
- Understand security testing approaches and methodologies
- Get sources and further readings on secure coding practices
