Israel’s peace treaty with Egypt after the Yom Kippur War gives Israel control of a 100-meter wide buffer between Gaza and Egypt.

A later agreement gave Egypt some limited control over the buffer zone, so there are Egyptian guards in charge of the border crossing now, but they can’t do whatever they want.
