Biti ya **No-Execute (NX)**, inayojulikana pia kama **Execute Disable (XD)** kwa lugha ya Intel, ni kipengele cha usalama kinachotegemea vifaa kilichoundwa kwa lengo la **kupunguza** athari za mashambulizi ya **kujaza kijizuu**. Ikiwa imeanzishwa na kuwezeshwa, inatofautisha kati ya maeneo ya kumbukumbu yanayokusudiwa kwa **mimbo inayoweza kutekelezwa** na yale yanayolenga **data**, kama vile **stack** na **heap**. Wazo kuu ni kuzuia mtu anayeshambulia kutekeleza kificho cha kudhuru kupitia udhaifu wa kujaza kijizuu kwa kuweka kificho cha kudhuru kwenye stack kwa mfano na kuongoza mtiririko wa utekelezaji kwake.

## Kupitisha

* Inawezekana kutumia mbinu kama [**ROP**](../rop-return-oriented-programing/) **kupitisha** ulinzi huu kwa kutekeleza vipande vya kificho kinachoweza kutekelezwa tayari kilichopo kwenye faili ya binary.
