Destroyer and the cost of ignoring identification procedure

In Destroyer, Captain Ella Markham regards her commission as a means of supporting research and treats fleet security procedures as needless suspicion. When an unidentified ship approaches the classified station, she assumes that knowing its location proves the visitor is authorized. Her subordinate asks for positive identification and later recommends a higher defensive condition because the thermal signature matches no known ship class. Those warnings are dismissed until the alarms identify a hostile cruiser. The station then loses main power and its defensive controls, while another unseen ship docks and boards. Markham launches an emergency communications drone carrying research backups and station records, then unlocks the small-arms caches and orders the occupants to defend themselves.
