My experience was that everything is grist for the mill. If you are studying from works later than 2015, the time of the revision of the domains from 10 to 8, you should be good.
The thing is truly to understand the domain, the fundamentals. What are the basics? Because the exam is adaptive that creates an advantage for those who have a broad-based knowledge.
My suggestion is:
Still reading my book but I been taking breaks here and there and seen some questions on ISC2 code of ethics and the book I have Official Study Guide by Sybex does not mention this - or at least I have not seen it - is this still a part of the 2018 test?
Oh it is there all right; and it is so much more important than ever.
Ethics means a lot of things to a lot of people, and I hope others will join the discussion.Security professionals face ethical dilemmas all the time as they serve their principals and their principles!
Got it and I agree esp when you find someone has deleted logs to cover up a mistake (which one of my peers has done in the past). Thank You!
Ouch! Sometimes it's better to say "Sorry," and eat your humble pie.
Ethics in and of itself, is a fascinating study of moral philosophy and is the basis of civilization (laws, business, social (antisocial) behavior.)
We got our notion of "the good" and "harmony" from Aristotle in Nicomachean Ethics; but ethics have been in all societies from the beginning. It's the glue that cements trust; so when ethics and trust are diminished, everything suffers.
And to bring it back to (ISC)2, I am certain you'll see a question or two about it, given it's importance to the infosec world.
