  Accreting white dwarfs (WDs) constitute a significant fraction of the hard
X-ray sources detected by the INTEGRAL observatory. Most of them are magnetic
Cataclysmic Variables (CVs) of the intermediate polar (IP) and polar types, but
the contribution of the Nova-likes systems and the systems with optically thin
boundary layers, Dwarf Novae (DNs) and Symbiotic Binaries (or Symbiotic Stars,
SySs) in quiescence is also not negligible. Here we present a short review of
the results obtained from the observations of cataclysmic variables and
symbiotic binaries by INTEGRAL. The highlight results include the significant
increase of the known IP population, determination of the WD mass for a
significant fraction of IPs, the establishment of the luminosity function of
magnetic CVs, and uncovering origin of the Galactic ridge X-ray emission which
appears to largely be associated with hard emission from magnetic CVs.
