A diffuse flux of high-energy astrophysical neutrinos has been detected with the IceCube Neutrino Observatory. This flux is dominated by neutrinos of extragalactic origin. However, a fraction of these neutrinos is expected to originate from cosmic rays interacting with the interstellar medium in our Galaxy. This flux has not been measured yet, but a detection could be within reach of IceCube's sensitivity. The signature of this flux with respect to the isotropic extragalactic flux is its close correlation with the galactic plane. The detection would contribute to the understanding of propagation and sources of galactic cosmic rays of typically PeV energies. In this talk the principle of an analysis using neutrino-induced through-going muons is presented and its sensitivity is discussed.
