President Sisi last evening signed into law an anti- terrorism legislation, details of which were published in the official gazette.
The controversial law sets up special courts and shields those enforcing it, such as the military and police, from legal consequences for the proportionate use of force "in performing their duties."
They also impose the death penalty for anyone found guilty of setting up or leading a terrorist group.
The government had initially proposed a jail sentence for offenders, but backed down after a backlash from local media.
Sisi, who toppled Islamist President Mohammed Morsi in 2013, had promised a tougher legal system in July, after a car bomb attack that killed the top public prosecutor, the highest level state official to be killed in years.
Egypt has witnessed many violent attacks by militants since the January, 2011 revolution that toppled the longtime president Hosni Mubarak.
North Sinai is one of the major areas that suffered major attacks by terrorists.
The military has launched security campaigns in the area, arrested suspects and demolished houses that belong to terrorists, including those facilitating tunnels leading to the Gaza Strip.
