  We study $S_{4}$ flavor symmetric inverse seesaw model which has the
possibility of simultaneously addressing neutrino phenomenology, dark matter
(DM) and baryon asymmetry of the universe (BAU) through leptogenesis. The model
is the extension of the standard model by the addition of two right handed
neutrinos and three sterile fermions leading to a keV scale sterile neutrino
dark matter and two pairs of quasi-Dirac states. The CP violating decay of the
lightest quasi- Dirac pair present in the model generates lepton asymmetry
which then converts to baryon asymmetry of the universe. Thus this model can
provide a simultaneous solution for non zero neutrino mass, dark matter content
of the universes and the observed baryon asymmetry. The $S_{4}$ flavor symmetry
in this model is augmented by additional $Z_{4}\times Z_{3}$ symmetry to
constrain the Yukawa Lagrangian. A detailed numerical analysis has been carried
out to obtain dark matter mass, DM-active mixing as well as BAU both for normal
hierarchy as well as inverted hierarchy. We have tried to correlate the two
cosmological observables and found a common parameter space satisfying the DM
phenomenology and BAU. The parameter space of the model is further constrained
from the latest cosmological bounds on the above mentioned observables.
