After studying for 40 hours within 8 days (from 2018/10/29 to 2018/11/05), I cleared the ISC2 CISSP-ISSMP (Information Systems Security Management Professional) exam today. This exam is one of the 3 CISSP concentrations. As its name denotes, this exam is all about basic management concepts and the difficulty level is not that high as far as an experienced CISSP is concerned.
My original plan of the year for learning and growth is scheduled to be completed by the end of October with one month buffer (November as the worst case). Since my goals are achieved ahead of the schedule, I decide to do more as final optimization using the one-month buffer, that is, the month of November.
