Title: SECURE CONTROLLER OPERATION AND MALWARE PREVENTION
Abstract:
In one implementation, a method for providing security on an externally connected controller (200) includes launching, by the controller (200), a kernel level security layer (206) that includes a whitelist of permitted processes (218) on the controller (200), the whitelist (218) being part of a custom security policy for the controller (200); receiving, at the security layer (206), a request to run a particular process; determining, by the security layer (206), a signature for the particular process; identifying, by the security layer (206), a verified signature for the process from the whitelist (218); determining, by the security layer (206), whether the particular process is permitted to be run on the controller (200) based on a comparison of the determined signature with the verified signature from the whitelist (218); and blocking, by the security layer (206), the particular process from running on the automotive controller (200) based on the determined signature not matching the verified signature for the process.
