  In this paper the requirement of a warp solution in an Einstein-Gauss-Bonnet
5D warped geometry is shown to fix the signature of Gauss-Bonnet coupling
($\alpha_{5}$). Further, imposing the phenomenological constraints, obtained
from the recently observed Higgs like scalar mass as well as $\mu$ parameter of
the decay channels ${H}_{0}\rightarrow\gamma\gamma,\tau{\bar \tau}$ explored in
ATLAS and CMS detectors, we obtain a stringent bound on $\alpha_{5}$ within
$(4.8 - 5.1)\times 10^{-7}$.
