  We discuss information theory as a tool to investigate constrained minimal
supersymmetric Standard Model (CMSSM) in the light of observation of Higgs
boson at the Large Hadron Collider. The entropy of the Higgs boson using its
various detection modes has been constructed as a measure of the information
and has been utilized to explore a wide range of CMSSM parameter space after
including various experimental constraints from the LEP data, B-physics,
electroweak precision observables and relic density of dark matter. According
to our study while the lightest neutralino is preferred to have a mass around
1.92 TeV, the gluino mass is estimated to be around 7.44 TeV. The values of
CMSSM parameters $m_0$, $m_{1/2}$, $A_0$ and $\tan\beta$ correspond to the most
preferred scenario are found to be about 6 TeV, 3.6 TeV, $-$6.9 TeV and 36.8
respectively.
