By holding the "Block key" (default=Mouse 4). If your mouse only has 3 buttons (1=Left, 2=Right, and 3=clicking the mouse wheel) you can go to Settings-> Keybindings and look for "Block" to change it to whatever feels comfortable.

You can read more about blocking and other moves on the Combat Maneuvers page.
