Searches for SUSY with the ATLAS detector

We present a review of the SUSY search strategies in ATLAS in conjunction with a current status of the detector obtained from the single LHC beam and cosmic data in 2008. The review will cover the analysis strategy based on the large missing Et signature plus jets, in which the number of methods are investigated for background estimation from data. The expected reach with inclusive analysis will be also shown. The review will also cover the special signatures expected from certain SUSY phenomenologies, in which the specific ATLAS detector components play a crucial role to detect and measure them.
