@PravPree Thank you for your inquiry! As with all (ISC)² exams, the CISSP exam is designed to gauge the candidates real world professional experience across the 8 domains. I have listed the link to the domain refresh FAQs for your convenience. The updates were minor, so if you feel comfortable with your work experience and the material you have studied, you can still sit for the exam. If you would like to wait, the new study material will be released during the summer of 2018.
