That said, recommending books specifically for the 401 is quite difficult since the GSEC exam by design covers such a wide range of topics. You'll need to know a little bit of practically everything - crypto, networking, Windows, UNIX, physical security, risk analysis, wireless, virtualization, incident handling, etc.. Perhaps using the study guides for Security+ and CISSP might be good starting points, as well as some Windows security resources (say, the Server 2008 Security Resource Kit and maybe a Red Hat security book). Try your hand at the free assessment to get a feel for the kind of questions the GSEC hits you on:https://www.sans.org/assessments/ If you've spent a decent amount of time in the IT industry with at least a little bit of exposure on the Windows and UNIX security side of things, the GSEC shouldn't be too difficult.
