It's possible to make into the EAGLE the Prohibition Areas for the footprint of the component?

Yes, there are a few different layers that can be used for that.
Right from manual (in "doc" folder on install directory) in section called
Define Forbidden Areas
Areas in the form of rectangles, polygons or circles in layers 41,
tRestrict, and 42, bRestrict, are forbidden for the Autorouter/Followme
router. No copper objects may be drawn in the top or bottom layers inside
these areas. These regions are tested by the Design Rule Check and taken
into consideration by the Autorouter/Followme router.
Layer 43, vRestrict, is for drawing restricted areas where the Autorouter
or the Followme router may not set vias. Manually placed vias in such a
vRestrict region are not examined by the DRC and therefore not reported as
an error.
Note that vias in vRestrict area will not create DRC error (which is a
problem CadSoft, that should be fixed IMHO). Why have a restrict area if
you don't report violations?
But these just restricts copper traces and vias. You can get component
restricts as well. Again, straight from manual section labelled Restricted
area for components
In layer 39, tKeepout, you should create a restricted area over the whole
component (RECT command). This allows the DRC to check whether components
on your board are too close or even overlapping.
Note that tKeepout becomes bKeepout automatically when a component is
mirrored in the layout.
No allowance for internal layer restrict areas as of yet. It's been
requested many times and perhaps EAGLE 6 will make that available.
Cheers,
James.
