Peleus here. Within Adobe, we do all that we can to secure our products, however, we can’t do everything on our own. Cooperation with the security community is essential to ensuring secure deployment of our products by our customers. Over the last year, Adobe has taken several measures to better interact with the security ecosystem including assisting groups such as OWASP, sponsoring conferences such as ShmooCon and CanSecWest, and building relationships with vendors and consultants. Our recent work with vendors to supply solutions for deploying SWF content securely is one example of these projects.
Coming out of the consulting world, I understood the challenges in analyzing a web site based on the Flash Platform. Although there were some basic tools and a handful of people with the appropriate knowledge, it was clear that more could be done. To solve this multi-faceted issue Adobe would need the assistance of the security community. From our end, we have been increasing our security documentation for developers, such as our Creating more secure SWF applications article, however, documentation can only go so far. We also needed to build alliances with vendors in the industry to help deliver the tools necessary to analyze production code.
This week, HP has stepped up to assist Flash developers by providing a free static analysis tool called SWFScan. SWFScan is able to perform static analysis on SWF content to identify common coding errors that can lead to vulnerabilities once the SWF is deployed. This allows developers to identify vulnerabilities earlier in the development cycle. Consultants who do not have access to source code can also leverage SWFScan to perform offline analysis of content by using it to decompile SWFs. SWFScan will work with ActionScript 2.0 and ActionScript 3.0 code and is free for everyone to use.
Last month, IBM launched AppScan 7.8 which can dynamically evaluate SWF content and perform penetration testing on a web site. Their tool is targeted at enterprise customers and allows users to enumerate flaws during the quality assurance phase of development. While static analysis can find many flaws, it is also important to analyze a SWF within the full context of its deployment. AppScan can monitor the SWF as it executes to identify flaws within the SWF’s run-time interactions with existing content as well as server communications through protocols such as AMF.
Both tools fit together nicely by allowing for security analysis at both the implementation and quality assurance phases of development. With these tools from HP and IBM, in addition to the work that Adobe does to help secure Flash Player and improve security documentation, our customers now have a more complete solution for deploying SWF content securely.
Within ASSET, we always try to examine the security of our products from as holistic a view as possible. Therefore, Adobe will continue to work with these and other vendors in the security community to bring together solutions that will help customers safely deploy our products and allow end-users to safely interact with them.
