(In)Secure C++: Sec Edition
Training aimed at providing an introduction to finding and exploiting vulnerabilities in C and C++ applications.
SECURE CODING PRACTICES IN C++
The training will provide its students with:
- knowledge on how to use tools to find vulnerabilities in native applications
- give a hands-on experience in some exploitation techniques
- Chat - Slack: Will be setup a week in advance to facilitate resolving of any technical issue
- Exercises - Cloud VMs and a Cyber Dojo cloud instance: guarantees same environment
This training is explicitly targeted at security professionals with some programming experience in C or C++.
GOALS OF THE TRAINING
- Demystify exploitation, show that exploitation is a mindset, not a set of techniques
- Demonstrate the motivation for mitigations in the platforms, languages and tools
- Show that C++ and C are not easy to reason about
- Teach the students to recognize constructs that have a higher risk of having vulnerabilities
- Teach the students which tools can be used to find bugs

Patricia Aas is an international speaker and has spoken at CppCon, ACCU, C++OnSea, NDC Security, NDC Oslo and many other conferences on subjects ranging from Sandboxing in Chromium to Vulnerabilities in C++. She has taught a range of subjects in Computer Science at the University of Oslo.
Patricia has a masters degree in Computer Science and 13 years professional experience as a programmer, most of that time programming in C++. During that time she has worked in codebases with a high focus on security: two browsers (Opera and Vivaldi) and embedded Cisco telepresence systems.
