In this ELCE talk, Jan Lübbe of Pengutronix reveals how syncing with upstream projects can keep Linux devices secure and functional for 10 years and beyond.
The good old days when security breaches only happened to Windows folk are fading fast. Malware hackers and denial of service specialists are increasingly targeting out of date embedded Linux devices, and fixing Linux security vulnerabilities was the topic of several presentations at the Embedded Linux Conference Europe (ELCE) in October.
One of the best attended was “Long-Term Maintenance, or How to (Mis-)Manage Embedded Systems for 10+ Years” by Pengutronix kernel hacker Jan Lübbe. After summarizing the growing security threats in embedded Linux, Lübbe laid out a plan to keep long-life devices secure and fully functional. “We need to move to newer, more stable kernels and do continuous maintenance to fix critical vulnerabilities,” said Lübbe. “We need to do the upstreaming and automate processes, and put in place a sustainable workflow. We don’t have any more excuses for leaving systems in the field with outdated software.”....
