Jeff J. Stapleton has over 30 years experience developing and assessing payment systems and security techniques, including cryptography and biometrics. His career includes the major card brands (MasterCard, Visa, American Express, and Discover) for payment systems and security assessments; big-four accounting firm experience performing security assessments of applications, systems, and products; working with large and medium-sized financial institutions providing risk assessments and security compliance audits; and developing policies, practices, and procedures for security systems. Jeff has participated in developing ISO and X9 security standards for over 25 years within the financial services industry. For the first five years, he participated on several X9 workgroups and has been an industry liaison and U.S. expert several times for various ISO workgroups. In addition, he has been chair of the X9F4 Cryptographic Protocols and Application Security Workgroup for 15 years. His experience includes participation on several X9 and ISO workgroups and development of over three dozen ISO and X9 standards. Some of the standards have multiple parts, which add to the overall count. Jeff has published articles in various information security journals, IEEE papers, PKI Forum notes, and is a contributing author to several books on biometrics and cryptography. He is also a patent holder for cryptographic solutions. Jeff has also authored various white papers for customers on debit card payments, key management, data loss prevention (DLP) solutions, and format-preserving encryption (FPE). He is a CISSP® and former Certified TG-3 Assessor (CTGA®) and PCI Qualified Security Assessor (QSA®). The CTGA and QSA are only viable for security consultants in active practice. He has also been a frequent public speaker at information security conferences, seminars, and webinars.
Jeff's extensive practical experience in applying information security and his expertise in cryptographic standards makes this book a must-read for the information security professional. Security without Obscurity: A Guide to Confidentiality, Authentication, and Integrity deserves a place in your reference library. —Ralph Spencer Poore, CFE, CISA, CISSP, CHS-III, PCIP, ISSA Distinguished Fellow, ISSA Honor Roll Having worked at the same consulting firm and also on a project with author J.J. Stapleton (full disclosure); I knew he was a really smart guy. In Security without Obscurity: A Guide to Confidentiality, Authentication and Integrity, Stapleton shows how broad his security knowledge is to the world. When it comes to the world of encryption and cryptography, Stapleton has had his hand in a lot of different cryptographic pies. He has been part of cryptographic accreditation committees for many different standard bodies across the globe. ... Those looking for a highly technical overview, interoperability guidance, and overall reference will find the book most rewarding. ... One of the ways Stapleton brings his broad experience to the book is in the many areas where he compares different types of cryptosystems, technologies and algorithms. This enables the reader to understand what the appropriate type of authentication is most beneficial for the specific requirement. ... For anyone looking for an authoritative text on how to fully implement cross-platform security and authentication across the enterprise, this is a valuable reference to get that job done. —Book review by Ben Rothke, writing on slashdot.org View the full review at: http://books.slashdot.org/story/14/06/16/1245237/book-review-security-without-obscurity … the author is well qualified to assay the vital information technology field of computer network security … The text is peppered with instructive figures and tables … very clearly written …—John Maxymuk for ARBAonline
