                Tips For Protecting Aviation Industry  Against GPS  Spoofing
                                                       Attacks:
            Obscure  or  hide    real  antennas.  Make  sure  the  commercial  aviation  are  not  visible  to  the  public
            by installing barriers or putting them in a place where they will not be seen.

            Choose   the   location   antennas   carefully.   They   will   need   a   clear   view   of   the   sky,   but   it   can   be
            wise to ensure that they are blocked from public locations and nearby buildings.


            Install  decoy  antennas.  Make  these  antennas  clearly  visible  and  put  them  at  least  300  meters
            away from your real ones.

            Add redundant antennas. Having more than one antenna in a slightly different location can help
            companies to spot potential issues quickly.

            Use  blocking  antennas.  These  work  to  protect  against  jamming  and  interference.  They  can  also
            lower the risk for spoofing attacks.

            Use   backups.   Inertial   sensors   can   help   to   determine   actual   position   and   cesium,   or   rubidium
            clocks  can  work  as  backup  timing  systems  when  GPS  is  down.  Backup  systems  that  do  not  rely
            on GPS are helpful in the event of an issue.

            Practice   good   cyber   hygiene.   When   not   needed   for   network   connectivity,   GPS   receivers   and
            associated   equipment   should   be   kept   offline.   Two-factor   authentication   should   be   in   place,
            passwords    changed    often,   and   updates   and   patches   installed   regularly.   Virus   protection,
            firewalls, and cyber defense practices should all be implemented.
