First, be calm: Do not panic; it may be very difficult to maintain composure if attacked but this is important.
Try to reason with the attacker: Establish communication with the person. This takes a lot of courage. However, a conversation may change the intention of an attacker.
Do not try anything foolish: If you know outmanoeuvring the attacker is impossible, do not try it.
Do not appear to be afraid: Look the attacker in the eye and demonstrate that you are not fearful. This may have a psychological effect on the individual.
