I was preparing to achieve a certificate, "Korea Information & Security Management Course" quite a while ago and I have a note for the class. I am going to organize the note and post the note in this community to help the future students who might prepare the same course I had. So I believe the contents accumulated here are going to contribute on the increased number of the page view from the numerous students who find the notes are useful for them. I have used Mindmapping program, [thinkwise], that is a quite useful tool to organize my thought and for creative thinking. I type the note from [thinkwise] program, and convert that into picture file(png) to help people who don't have the program but want to use my contents. Feel free to use the contents below.
