Not sure what you mean by the social security need to be bourne by you. If you're on a French payroll, you'll have something like 22 to 25% of your gross salary deducted for social security, with the remaining portion paid by the employer. (And the employer portion amounts to 35 - 40% of your gross salary.) Income taxes are usually on you, as are your accommodation costs (unless you're a temporary transfer).
The salary you've been offered is actually pretty good for the Paris area. Yes, housing costs are pretty high if you want to live in Paris or the immediate surroundings. You should probably ask to see where your colleagues live - there are some savings to be had living out in the suburbs, plus the employer picks up half the cost of a monthly transport pass. But the ultimate cost of living will depend quite a bit on your expectations and your ability to adapt.
