This enhancement calls for terminating remote sessions or connections, such as those used by ground operators, when certain conditions are met (e.g., inactivity, contact window closure). Communication sessions are intermittent in a typical satellite operation due to orbital geometry and scheduling constraints. Once a pass ends or after operators complete mission activities, the spacecraft should automatically sever links to prevent adversaries from exploiting leftover connections. For instance, if a ground station unexpectedly loses power or experiences network disruption, a lingering open session might invite replay attacks or misrouted commands. Engineers reduce the risk of unauthorized post-session access by designing the space vehicle to detect contact cessation and terminate the session. Additionally, scheduling forced session termination at the end of each communication window can conserve limited on-board resources and ensure the spacecraft remains nominally secure, ready to authenticate fresh commands during the next pass.
