Hi, I'd like to understand what the different possibilities to control file and network access are (e.g. to implement a personal firewall which is able to control all running apps)? On a traditional Linux I'd choose a LSM hooks based approach to control all file and network access. Depending on the exact architecture that would mean I also had to deploy a kernel module which is able to communicate (e.g. netlink) with my application running in the user space. Such an approach would make it impossible to distribute the application through the AppStore. Is there any better approach?
Yesterday Symantec announced [1] the release of such a mobile security solution. Apparently it has an integrated firewall. How is that possible with the given Android security model? Can someone shed some light on the architecture of such a solution? Thanks and regards, Yves [1] http://www.symantec.com/about/news/release/article.jsp?prid=20100527_01
