TALK 1: Introduction to Buffer Overflow vulnerabilities by Ravi Vashatkar

Buffer overflows are well known in the security industry to be one among the oldest vulnerabilities that exist even today.

We'll cover
- What is Buffer overflow ?

- An overview of CPU registers and Assembly language.
- How can stack buffer overflow vulnerability be exploited ? (Practical demonstration)
- How to prevent and/mitigate these vulnerabilities.

TALK 2: Securing web applications with minimal resources by Aivaras Prudnikovas

Competitive environment, expectations of users and authorities require one to find better and more efficient solutions to securing applications. User authentication is one of the first cross cutting concerns one needs to implement and yet it is always challenging and time consuming. How do you reduce time, resources and increase security at the same time? Would you invest in your engineers or buy services of a third party authentication provider or maybe do something in between? After working on various authentication implementations starting with ad-hoc approaches to integrating with third party auth vendors there is no single answer - the devil is in the details.
