CISSP Cert Guide

Robin M. Abernathy has been working in the IT certification preparation industry for more than 20 years. She has written and edited certification preparation materials for many (ISC)2, Microsoft, CompTIA, PMI, ITIL, ISACA, and GIAC certifications and holds multiple IT certifications from these vendors. Robin provides training on computer hardware and software, networking, security, and project management. Over the past decade, she has ventured into the traditional publishing industry by technically editing several publications and co-authoring Pearson's CISSP Cert Guide and CASP+ Cert Guide and authoring Pearson's Project+ Cert Guide. She presents at technical conferences and hosts webinars on IT certification topics. Dr. Darren R. Hayes has close to 20 years of academic and professional experience in computer security and digital forensics. He has authored numerous publications in these fields, including A Practical Guide to Digital Forensics Investigations, which is published by Pearson. He is Associate Professor at Pace University, where he is the founder and director of the Seidenberg Digital Forensics Research Lab. He holds numerous IT certifications in security and digital forensics and holds a PhD from Sapienza University in Italy and a doctorate from Pace University. Darren is also a professional digital forensics examiner and has supported both criminal and civil investigations over the past decade and a half. He has also been declared an expert witness in federal court.
