Example embodiments of the present disclosure relate to methods, devices, apparatuses and a computer-readable medium for communication to enhance security for path switching between relay terminal devices. In an example method, based on determining that path switching from a source relay terminal device having a first relay service code (RSC) associated with a first set of security policies is triggered, a remote terminal device determines a second RSC. The remote terminal device obtains a second set of security policies associated with the second RSC.
