Certified information systems security professional

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 "ISC2" formed in mid-1989 as a non-profit organization.[8]

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.[9]

In 2003 the CISSP was adopted as a baseline for the U.S. National Security Agency's ISSEP program.[10]

The CISSP curriculum breaks the subject matter down into a variety of Information Security topics referred to as domains.[11] The CISSP examination is based on what ISC2 terms the Common Body of Knowledge (or CBK). According to ISC2, "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."[12]

On 1st May 2021 there was a domain refresh that impacted the weighting of the domains; the domains themselves did not change.[13]

From 15 April 2018, the eight domains covered are :[14]

1. Security and risk management
2. Asset security
3. Security architecture and engineering
4. Communication and network security
5. Identity and access management (IAM)
6. Security assessment and testing
7. Security operations
8. Software development security

From 2015 to early 2018, the CISSP curriculum was divided into eight domains similar to the latest curriculum above. The only domain to have changed its name was "Security Engineering," which in the 2018 revision was expanded to "Security Architecture and Engineering."[15]

Before 2015, it covered ten domains:[16]

1. Operations security
2. Telecommunications and network security
3. Information security governance and risk management
4. Software development security
5. Cryptography
6. Security architecture and design
7. Access control
8. Business continuity and disaster recovery planning
9. Legal, regulations, investigations and compliance
10. Physical (environmental) security

• Possess a minimum of five years of direct full-time security work experience in two or more of the ISC2 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.[17] A candidate without the five years of experience may earn the Associate of ISC2 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.[18]
• Attest to the truth of their assertions regarding professional experience and accept the CISSP Code of Ethics.[19]
• Answer questions regarding criminal history and related background.[20]
• Pass the multiple choice CISSP exam (four hours, up to 175 questions, in an adaptive exam) with a scaled score of 700 points or greater out of 1000 possible points, you must achieve a pass in all eight domains.[20]
• Have their qualifications endorsed by another ISC2 certification holder in good standing.[21]

Number of CISSP members as of July, 2022 is 156,054.[1]

Holders of CISSP certifications can earn additional certifications in areas of speciality. There are three possibilities of the concentrations as listed below.[22]

The standard exam costs $749 US as of 2021.[29] On completion of the exam, to gain certification you need to complete an endorsement process to evidence at least five years experience within a mix of the domains. A dispensation can be claimed for one year with the relevant academic qualification. The final step is payment of the annual maintenance fee of $125 (as of 2020).

The CISSP credential is valid for three years; holders renew either by submitting 40 Continuing Professional Education (CPE) credits per year over three years or re-taking the exam.

CPE credits are gained by completing relevant professional education.

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.[30][31]

In 2008, another study came to the conclusion that IT professionals with CISSP (or other major security certifications) and at least 5 years of experience tend to have salaries around US, about US (or 26%) higher than IT professionals with similar experience levels who do not have such certificates.[32] Note that any actual cause-and-effect relationship between the certificate and salaries remains unproven.

As of 2017, a study by CyberSecurityDegrees.com surveyed some 10,000 current and historical cyber security job listings that preferred candidates holding CISSP certifications. CyberSecurityDegrees found that these job openings offered an average salary of more than the average cyber security salary.[33]

ANSI certifies that CISSP meets the requirements of ANSI/ISO/IEC Standard 17024, a personnel certification accreditation program.[2]
