Certified Information Systems Security Professional
Certified Information Systems Security Professional (CISSP) is an independent information security certification governed by the International Information Systems Security Certification Consortium, also known as (ISC)².
As of June 1st 2015, there are 100,102 (ISC)² members holding the CISSP certification worldwide, in 160 countries. In June 2004, the CISSP obtained accreditation by ANSI ISO/IEC Standard 17024:2003 accreditation. It is also formally approved by the U.S. Department of Defense (DoD) in both their Information Assurance Technical (IAT) and Managerial (IAM) categories for their DoDD 8570 certification requirement. The CISSP has been adopted as a baseline for the U.S. National Security Agency's ISSEP program. CISSP is a globally recognized certification in the field of IT security.
In the mid-1980s a need arose for a standardized, vendor-neutral certification program that provided structure and demonstrated competence. In November 1988, the Special Interest Group for Computer Security (SIG-CS), a member of the Data Processing Management Association (DPMA), brought together several organizations interested in this goal. The International Information Systems Security Certification Consortium or "(ISC)²" formed in mid-1989 as a non-profit organization.
By 1990, the first working committee to establish a Common Body of Knowledge (CBK) had been formed. The first version of the CBK was finalized by 1992, and the CISSP credential was launched by 1994.
Certification subject matter
The CISSP curriculum covers subject matter in a variety of Information Security topics. The CISSP examination is based on what (ISC)² terms the Common Body of Knowledge (or CBK). According to (ISC)², "the CISSP CBK is a taxonomy – a collection of topics relevant to information security professionals around the world. The CISSP CBK establishes a common framework of information security terms and principles that allow information security professionals worldwide to discuss, debate and resolve matters pertaining to the profession with a common understanding."
From 2015, the CISSP curriculum is divided into eight domains:
- Security and Risk Management
- Asset Security
- Security Engineering
- Communications and Network Security
- Identity and Access Management
- Security Assessment and Testing
- Security Operations
- Software Development Security
Before 2015, it covered ten similar domains.
- Possess a minimum of five years of direct full-time security work experience in two or more of the (ISC)² information security domains (CBK). One year may be waived for having either a four-year college degree, a master's degree in Information Security, or for possessing one of a number of other certifications. A candidate without the five years of experience may earn the Associate of (ISC)² designation by passing the required CISSP examination, valid for a maximum of six years. During those six years a candidate will need to obtain the required experience and submit the required endorsement form for certification as a CISSP. Upon completion of the professional experience requirements the certification will be converted to CISSP status.
- Attest to the truth of their assertions regarding professional experience and accept the CISSP Code of Ethics.
- Answer questions regarding criminal history and related background.
- Pass the multiple choice CISSP exam with a scaled score of 700 points or greater out of 1000 possible points. 
- Have their qualifications endorsed by another (ISC)² certification holder in good standing. 
Holders of CISSP certifications can earn additional certifications in areas of specialty. There are three possibilities:
1. Information Systems Security Architecture Professional (CISSP-ISSAP)
2. Information Systems Security Engineering Professional (CISSP-ISSEP)
3. Information Systems Security Management Professional (CISSP-ISSMP)
The CISSP credential is valid for three years. It can be renewed by re-taking the exam, but most holders renew by submitting Continuing Professional Education (CPE) credits. To maintain the CISSP certification, a certificate holder is required to earn and submit a minimum of 40 CPEs each year and 120 CPEs by the end of their three-year certification cycle.
For those holding one or more concentrations, CPEs submitted for those concentrations count toward the CPEs required for the CISSP.
CPEs can be earned in several ways, including taking classes, attending conferences and seminars (online and in person), teaching others, undertaking volunteer work, and professional writing. Most activities earn 1 CPE for each hour of time spent, but preparing (but not delivering) training for others is weighted at 4 CPEs/hour, published articles are worth 10 CPEs, and published books 40 CPEs.
In 2005, Certification Magazine surveyed 35,167 IT professionals in 170 countries on compensation and found that CISSPs led their list of certificates ranked by salary. A 2006 Certification Magazine salary survey also ranked the CISSP credential highly, and ranked CISSP concentration certifications as the top best-paid credentials in IT.
In 2008, another study came to the conclusion that IT professionals with CISSP (or other major security certifications) tend to have salaries $21,000 higher than IT professionals without such certificates. However, there's no proof that there's any cause-and-effect between the certificate and salaries.
