There are several points about security in this discussion, and I would like to make what I think is a good point. With Linux, you can specify how a system can be accessed. Meaning, if you're doing something that could potentially be considered a security hazard, then you can lock that system down tight as a drum.
You can do various things, such as: - Completely disable root - Limit access to a terminal( local access only ) - Run several different IPC mechanisms for system abstraction - Run a chroot jail And a lot more . . . So in a case where you're using the PRU's and / or dev/mem/ for data acquisition. You do *NOT* allow remote logins - period. Then the data is perhaps saved to a remote NFS share. Then, to maintain your "IoT" system, you log in through a physical serial connection. Pretty simple. But this is just one of many potential security strategies. However, it should be realized that when a system is internet facing. There will always be a risk . . . -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
