The metal surface is not allowed to come in contact with moisture, O2 and CO2. i) Coating the metal surface with paint.
ii) Applying oil or grease. iii) Electroplating with non-corroding metals like Ni, Cr, Al, Sn, Zn.
iv) Coating with alkaline phosphate (anti rust) solution.
Sacrificial protectionCovering the surface with a more electro positive metal than Fe. The more electro positive metal loses electrons and as long as this coating is present Fe is protected. Example:
Galvanization - Covering with zinc. The zinc also forms a protective coating of ZnCO3.Zn(OH)2.
Electrical protection (Cathodic protection)The iron object is connected to a more active metal either directly or through a wire. Fe acts as the cathode. The more reactive metal is the anode. It loses electrons and gradually disappears. Example: Fe can be connected to Mg, Zn or Al which are called the sacrificial anodes. Used for protecting under ground pipes from rusting.

no it just oils it+++ It will for a time but oil loses its efficacy as a protective fairly quickly, depending on conditions.
What are the conditions necessary for rusting?
The conditions necessary for rusting are water (or water vapour) and air, specifically Oxygen. If one condition is absent and the other is present then rusting would not occur but if both are present then rusting will occur
