Meeting Schedule May 28th 2009: AppSec Europe 2009
Summary The main goal of the upcoming OWASP-NL meeting is to provide an abstract of the recently held AppSec Europe 2009, a VAC about CSRF and, new, an open discussion on application security subjects brought forward by the attendees.

18.30 – 18.45 Introduction (OWASP organization, projects, sponsor) 

18.45 - 19.45 AppSec-EU 2009 (Sebastien Deleersnyder, Telindus)  Update on the AppSec-EU 2009: OWASP State of the union, an update on OWASP and OWASP projects and of course the highlights of the AppSec-EU 2009 presentations.

19.45 – 20.00 Break 

20.00 – 20.30 VAC Cross-Site Request Forgery (Niels Teusink, Fox-IT)  CSRF is an attack which forces an end user to execute unwanted actions on a web application in which he/she is currently authenticated. With a little help of social engineering (like sending a link via email/chat), an attacker may force the users of a web application to execute actions of the attacker's choosing. A successful CSRF exploit can compromise end user data and operation in case of normal user. If the targeted end user is the administrator account, this can compromise the entire web application.

Niels Teusink holds a bachelor degree in Computer Science and has been experimenting with IT security for over a decade. He has worked for Fox-IT since 2005; first as a software engineer and since 2007 as a penetration tester. He has since performed dozens of penetration tests for all sorts of companies, including governments, banks and nuclear installations.

20.30 – 21.15 Open session / discussion (Martin Knobloch/Ferdinand Vroom/Peter Gouwentak)  Open session / discussion about subjects brought forward by the attendees.

Meeting Schedule 9th April Knowing Your Enemy
Summary The main goal of the upcoming OWASP-NL meeting is to provide information to managers, architects, designers, developers and security and risk professionals. The speakers will give specific examples and there will be time to ask questions.

18.30 – 18.45 Introduction (OWASP organization, projects, sponsor)  18.45 - 19.30 Modern information gathering; how to abuse search engines            Dave van Stein ([[Media:20090409_passsive_reconnaissance_Dave_van_Stein.pdf]]) Great generals already know the key to success is "knowing your enemy". In hacking terms this is called information gathering, fingerprinting or reconnaissance. Traditionally this phase consisted of using public records like WHOIS and DNS combined with active scans on servers. With the rise of advanced search engines like Yahoo, Live Search and Google a whole new type of reconnaissance has come to life; passive reconnaissance. Often servers are not properly configured which causes lots of valuable information to become available without accessing the server at all. Recently several hacker-tools appeared which use the full capabilities of these search engines giving hackers a head-start at mapping the network they plan to attack. The goal of this session is to give insight in the methods and tools hackers have at their disposal to gather information about systems they plan to attack without accessing the system itself. Dave van Stein has close to 8 years of experience in software testing. Since the beginning of 2008 he’s working for ps_testware as a web application security testing specialist.

19.30 – 20.00 VAC Cross-site scripting     Martin Visser ([[Media:20090409_VAC_Cross-site-scripting_Martin_Visser.pdf]]) Martin Visser is a software designer with Sogeti Nederland B.V. specialized in secure application development with Microsoft technologies. He has experience with Microsoft server technologies like ASP.NET, SharePoint and Biztalk. Martin also developed and teaches a 2-day "Application Security – Microsoft development" course both within and outside Sogeti.

20.00 – 20.15 Break  20.15 – 21.00 Beveiligingsaspecten van webapplicatie-ontwikkeling Wouter van Kuipers  ([[Media:20090409_presentatie_Wouter_van_Kuipers.pdf]]) Het ontwikkelen van webapplicaties verschilt op verschillende aspecten met het ontwikkelen van desktop applicaties, met name op het gebied van security. Voor grote bedrijven zijn er oplossingen beschikbaar als bijvoorbeeld SDL, maar voor het midden- en kleinbedrijf zijn dit soort oplossingen beperkt, omdat zij vaak niet de middelen hebben om dergelijke strategieën uit te kunnen voeren. Voor zijn scriptie heeft Wouter van Kuipers middels een literatuuronderzoek, interviews met ontwikkelaars en een onderzoek naar Fortify 360 gekeken hoe het midden- en kleinbedrijf omgaat met deze verschillen en hoe zij het ontwikkelproces kunnen optimaliseren op het gebied van security.

Na een MBO opleiding in de IT is Wouter van Kuipers via de HBO opleiding 'Communicatie Systemen' begin 2007 begonnen met een master Informatiekunde aan de Radboud Universiteit Nijmegen, welke hij in maart dit jaar hoopt af te ronden. Tijdens zijn MBO studie is zijn interesse in het ontwikkelen van webapplicaties gewekt, wat in 2003 resulteerde in het opzetten van een eigen web-development bedrijf. Dit bedrijf is met name gespecialiseerd in het ontwikkelen van webapplicaties op maat, en het ondersteunen van bedrijven op het gebied van web-developement op freelance basis.
