Hello @cyberdude

Thank you for you response! 


The CBK has not been updated but, I would say that there is a lot of good information that is still relevant to the CSSLP.  I would also encourage you to download the Exam Outline as that is a good reference for self-study. In addition to the Exam Outline, we also have a CBK reference list that would be helpful with self-study We also have flash cards available for an additional self-study resource. 


If you have any additional questions regarding the current CSSLP Online Instructor-Led course or any of the resources provided, please do not hesitate to contact me directly and I will provide the assistance needed.


I hope this helps!

I am looking for some additional / updated materials to prepare the CSSLP, with no success so far.


Why isn’t there any practice questions book as in most of the other (ISC)2 certifications? I guess that many people is in our situation and would like to see something like this soon.


Thanks and Regards,
