It depends on your personal play style, but the best way to survive vs the computer (in my opinion) is to adopt a 'turtle' play style.
This means when you start off, pump out a power plant, barracks, refinery. Build about 10 infantry, and then spend all your income on base defenses.
Make sure you cover all possible entrances to your base.
Once that is done, use the infantry to either plug any holes in that perimeter, or go scouting the map.
Should be able to just build your way up then without the fear of being overrun.
