This response is to the latter question posed in your post: "What is the difference between direct lightning stroke and indirect lightning stroke?" A direct strike is one in which the lightning attaches directly to your structure, and you have to design such that the physical effects of the lightning do not damage the structure, or damage is held to an acceptable level. This typically involves having enough metal to take the current without overheating and deforming or exploding. Indirect effects means the lightning strikes something nearby, or even your structure, but you are dealing with the magnetic coupling effects of the large induced currents. The magnetic fields from the current and the current rate of change couple potentials and currents into electrical cables, and you have to design once again for no damage and no upset, or an acceptable level of upset. Don't know what you are working on but in aerospace, direct effects are controlled by RTCA/DO-160 section 23, whereas indirect effects are controlled by section 22 of the same standard. RTCA/DO-160 is "Environmental Conditions and Test Procedures for Airborne Equipment," and is available, for a price, from the Radio Technical Commission for Aeronautics.
