Other Comments for consideration

As examples, following items are not in the current objectives:

1) Related to Forensics: In the survey of malware’s behavior, Sleuth Kit would be used to analyze the hard disk on Linux machine. Also in some cases, LVM commands would be used to restore the disk which became un-mountable. So that this area should be learned.

This is an interesting topic, but it goes beyond basic security in the sense it "prevention and defending". This is postmortal analysis. As the exam already contains a lot of topic this is postponed but up to discussion (fth)

2) polkit
