The agenda:

  • 18h15 - 19h00: Welcome & sandwiches
  • 19h00 - 19h15: OWASP Update
  • 19h15 - 20h15: Writing robust client-side code using Modern JavaScript (by Tom Van Cutsem, Bell Labs, Nokia)
Abstract: In this talk, I will take the audience on a tour of recent evolutions in the JavaScript language (and surrounding ecosystem) and how they can use these changes to their advantage to write better client-side code that is more robust against bugs and other exploits. JavaScript — still unquestionably the dominant client-side language in use on the Web — has evolved significantly over the past five years, with two significant updates to ECMAScript, its defining standard. I will give a brief introduction to the language and its Good and Bad parts and then move on to features added in ECMAScript 5th edition, such as "strict mode", which are by now widely deployed in major browsers. Next, I will look at relevant language features that were introduced recently as part of ECMAScript 6th edition. Finally, I will give a brief introduction to Secure ECMAScript (SES), which is a secure JavaScript dialect that enables the safe embedding of third-party scripts in a webpage, also forming the basis for Google’s Caja compiler.
Bio: Tom Van Cutsem is a senior researcher at Nokia Bell Labs in Antwerp, Belgium. Prior to joining Bell Labs, he was a professor of computer science at Vrije Universiteit Brussel. He sat on the ECMA TC39 committee in charge of standardising JavaScript and actively contributed to the ECMAScript 2015 (a.k.a. “ES6”) standard. Together with Mark S. Miller, he designed and specified ECMAScript’s new reflection API. Tom's broader research interests lie in distributed systems, programming languages, stream processing, concurrency and parallelism. He received his PhD in 2008 from Vrije Universiteit Brussel for his research on AmbientTalk, a distributed scripting language for mobile phones.
  • 20h15 - 20h30: Break
  • 20h30 - 21h30: Internet censorship on Social Media (by prof. Dan Wallach, Rice University)
Abstract: TBA
Bio: Dan Wallach is a professor in the systems group at Rice University's Department of Computer Science, He manages Rice's computer security lab. His research interests include mobile code, wireless and smartphone security, and the security of electronic voting systems.
