Once you are through security you should be a bit more heightened with what's going on around you. Keep an eye on your luggage and all personal belongings. Keep an ear for announcements by the gate. Plus, announcements over the main intercom. Granted a lot of times those announcements won't refer to you. However, if there is a major terror attack the announcement will be made over that intercom. If the airport is being shutdown they will announce instructions as to what people should do. So it would probably be best if you listened to not just the warning announcement, but ones that followed as well.
