Players create defenses for their bases in both singleplayer and Multiplayer for multiple reasons. Singleplayer defenses are usually for defending against hostile mobs such as Creepers. Multiplayer defenses are usually for keeping unwanted Players or hostile mobs out.
Playing on hard difficulty presents the challenge of Zombies breaking into a player's home. This is a common situation that all players should be prepared to defend against. While using iron doors instead of wooden doors is very common, there is a more resourceful way to prevent zombies from breaking down a door. Zombies in Minecraft can only break closed doors, and there is a way players can use this to their advantage. Place a wooden door up against a block in the open position. Then simply "close" the door and zombies will get confused, thinking the door is open, even though it is actually closed.
Are Spiders climbing over walls? There is an easy way to prevent this. All players have to do is create a "lip" or overhang above the outside of their walls. Spiders will not be able climb around the overhang and will instead fall down, because they can only climb vertically.
Being chased by hostile mobs can quickly cause players to lose hunger. A great technique to prevent chases is to make diagonal paths. Diagonal paths are only useful in preventing being chased when there is lava around the diagonal path. Creating diagonal paths is easy and simple. All that a player must do is place blocks, making sure only one corner of the blocks touches another corner of a different block. Since mobs can't walk diagonally, this technique is fool-proof, and will leave pursuers in the dust.
Place a dispenser and fill it with arrows. Next place a trigger such as a pressure plate or a tripwire. Finally, connect the trigger to the dispenser. Make sure the redstone is not visible, otherwise raiders will be careful to avoid the trap.
A potion shooter is similar to the arrow shooter trap above, but instead of arrows being dispensed, Splash Potions and/or Lingering Potions are used. Potions of harming are the most effective to use in the dispenser. Use a similar setup as the arrow shooter. However, make sure the splash potions actually hit their target, as they work slightly different than arrows.
