The Information System Security Engineering Professional (ISSEP) is a CISSP concentration that specializes in security engineering. In addition to the ISSEP, there are two other CISSP concentrations, the Information System Security Architecture Professional (ISSAP) and the Information System Security Management Professional (ISSMP). The ISSAP overlaps with many of the technical concepts from the CISSP, the ISSMP overlaps with many of the management aspects. The ISSEP is an entirely different animal with a distinctive U.S. government flavor to it.
About the Exam
The ISSEP exam is made up of 150 questions and has a four hour time limit. Like other ISC2 test, 25 of these questions are used for research purposes only and are not counted when determining your grade. You need a 700/1000 to pass the exam. The domains and questions were developed by ISC2 in conjunction with the U.S. National Security Agency (NSA). Because of the NSA’s participation in question development, you may notice a different style and tone between ISSEP and CISSP questions.
