First steps into security engineering

English session - Beginner

Experience with security is a useful and even profitable skill for every technical and non-technical employee in IT. Contrary to common stereotypes, security is far more than black hoodies, math and crypto. It's also humans and communication skills. Attendees of my talks regularly ask me how to get started. Let me introduce you to diverse areas of info sec and point you to books, online courses, talks, and other resources to get you started.

Profiling and tracing with ptrace, perf and SystemTap

English session - Intermediate

Modern OS and CPUs come with a variaty of APIs for monitoring. Ptrace based commands like strace are easy to use but slow. Perf allows lightweight profiling. SystemTap is a powerfil toolkit plus DSL to instrument probe points inside the Kernel as well as static SystemTap/DTrace markers in libs and languages like Java, PHP, and Python. In my talk I'll show and compare various low and high level tools as well as visualization (e.g. flame graphs).
