Which Drupal modules can you trust?

Software we build depends on an aweful lot of other software, our framework (Drupal), third party modules, libraries (server side and client side!), PHP and it's extensions, Webserver (Nginx / Apache), OS (Linux), etc.

The question with security audits is always, how far do we goWhat third party software should and shouldn't we audit?

For an application that uses Drupal, it's pretty clear that we should audit the custom configuration and code as well as verify that all third party library versions used do not contain known vulnerabilities. But should we audit Drupal? Should we audit a popular third party module like Views? How about a less popular one like the Feeds REGEX Parser? What if a Alpha, Beta or Devel version is used?

To help with decision making we built and released the Ibuildings Drupal Security Audit tools.

    "So tell me, why do you use PHP, really?"

    I'm sitting at the conference dinner, in the cargo room of the Cap San Diego in Hamburg Germany, supposedly the 'largest cargo ship seaworthy museum in the world'. Across from me is a German student and OWASP volunteer. We've been talking for a while now, he looks forward to a future in pentesting so he volunteered to help with OWASP AppSec Research 2013. AppSec is a conference for Application Security, hosted by the Open Web Application Security Project (OWASP). Sometimes they add 'Research' to it to encourage researchers to come and speak.

    'Sigh. Here we go again' I think as I hear conversation around us stop, people listening in.

    4 HTTP Security headers you should always be using

    What started as a dream for a worldwide library of sorts, has transformed into not only a global repository of knowledge but also the most popular and widely deployed Application Platform: the World Wide Web.
    The poster child for Agile, it was not developed as a whole by a single entity, but rather grew as servers and clients expanded it's capabilities. Standards grew along with them.

    While growing a solution works very well for discovering what works and what doesn't, it hardly leads to a consistent and easy to apply programming model. This is especially true for security: where ideally the simplest thing that works is also the most secure, it is far too easy to introduce vulnerabilities like XSSCSRF or Clickjacking.

    Because HTTP is an extensible protocol browsers have pioneered some useful headers to prevent or increase the difficulty of exploiting these vulnerabilities. Knowing what they are and when to apply them can help you increase the security of your system.

    Co-development teams

    Bij onze software development trajecten werken wij met projectteams. Afhankelijk van het soort en de omvang van het project wordt een team samengesteld op basis van de specifieke technische kennis en kunde van de developers. Vaak bestaat een team volledig uit developers van Ibuildings, maar we werken ook in co-development teams waarbij naast developers van Ibuildings ook eigen developers van de klant aan het project werken. 

    Bij zo’n co-development traject is het noodzakelijk om extra aandacht te besteden aan een goede fundering voor het project. Naast een introductie in de tools die Ibuildings gebruikt bij software development projecten, moet er ook overeenstemming zijn over de werkwijze die aan het project ten grondslag ligt. Met andere woorden, ervoor zorgen dat we als team dezelfde taal spreken.

        Workshops, workshops everywhere

        Ibuildings organiseert regelmatig een interne workshop. Hierbij worden (veelal) technische onderwerpen behandeld en aan de hand van een opdracht verder uitgewerkt.

        Maar hoe maak je een workshop over Symfony 2 en Domain Driven Design (DDD) interessant voor iedereen?

        Secure your REST API with OAuth2 Implicit Grant

        These last few years have seen the rise of some amazing frameworks oriented towards Single Page Application (SPA) like ExtJS, AngularJS, Backbone, Ember, etc. Following the trend where Front-end and Back-end separate. Client side technologies are now being managed by one team and Back-end services by another. This Separation of Concerns is wonderful for implementors as you only need a specification of the API and you can develop functionality concurrently. However all this client-side functionality often leaves the question: How are we going to secure the API if, at least in theory, it should be open for the browser of any device anywhere on earth? (no, we do not support the ISS).

          ETags for the Uninitiated

          Yet, ETags are one of the features that are the hardest to get right. Sometimes it’s not even clear how they work and while there’s a lot out there on the subject, it can also be difficult to put it all together. Developers frequently play either client and server roles in this exchange, which can make the responsibilities even more confusing.

          In this series of blog posts, we’re going to look at ETags from both perspectives: First, a client trying to consume an ETag-enabled API. By focusing on the client side, we can focus on the features ETags offer and learn how these are supposed to look in a perfectly implemented world. In a later post, we’ll look at the gory details of how that API implements ETags and does the appropriate checks.

            Verifying our software with OWASP ASVS

            "If a tree falls in a forest and no one is around to hear it, does it make a sound?"

            Likewise if a software project is delivered and no one has looked at security, can it be said to be secure?

            If a tree falls... by Dunc(an) When a customer commissions Ibuildings for a new application, he usually has plenty of functional demands (I need it to do X and also Y and Z... oh and can I get A?). And maybe some thoughts have been given to performance metrics, but security? Well... it "needs to be secure".

              Boosting mobile deployment with PhoneGap Build

              In July 2011 Nitobi (now acquired by Adobe) released a stable version of a small library called PhoneGap. It's main purpose was to close the gap between web- and native applications. This was achieved by wrapping web applications in a native app for each supported platform. Another feature to close the gap is to expose Javascript API's for functionality which is otherwise only available to native applications.

              Scalability issues: cure first, prevent later

              Episode: 2012 - 26
              Thijs Feryn 
              The "it works on my machine" mentality has resulted in numerous face palm moments. This is even more painful when a your app is under heavy load due to a marketing campaign. With some minimal code changes and some smart utilities, you can maximize your scalability and performance. Keywords: Varnish, PHP-FPM, Nginx, APC, CDN, Gearman, Memcached and a proper server setup. I'll show you how you can make a slow app with a crappy code base go mighty fast on one and even multiple servers. The focus of this talk is to cure first and eventually learn and prevent.

              DPCRadio: The API Dilemma

              Episode: 2012 - 30
              Chris Cornutt 
              Creating a good, useful and functional API for your application can be one of the most difficult parts of a project. With more and more things becoming API-powered, it's important to plan well and provide what the user expects. I'll look at some principles you can follow to make sure the API you write is the right one, both from the developer perspective and what you, as a user, should expect of a quality web service API.

              DPCRadio: Travis CI - Distributed CI for the masses!

              Episode: 2012 - 16
              Josh Kalderimis 
              Continuous Integration has typically been a practice only performed by companies who want that piece of mind for their client software, but does it need to be like this? Travis CI is a continuous integration service for the open source community. We make testing OS projects dead simple and fun. But most importantly, we help improve code quality for large projects like Doctrine2 and symfony, to smaller libraries like FOSRest. The vision behind Travis CI is to become for builds what PEAR is for distributing libraries. In this talk Josh, one of the core members of the Travis CI team, will introduce you to the vision behind Travis, the how it is implemented, and why it matters to everyone in the OS community.
