Public order and public security
Section 11(3) · 1999 Constitution (2004 edition)
What Constitution says
(3) During any period when the Federation is at war the National Assembly may make such laws for the peace, order and good government of the Federation or any part therefore with respect to matters not included in the Exclusive Legislative List as may appear to it to be necessary or expedient for the defence of the Federation.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
