Demystifying CISSP: Understanding the Core Concepts and Domains



Employment in IT and cybersecurity can be both challenging and satisfying. In a world of cyber attacks, malware, and computer viruses, all businesses need professionals who are experts in data protection.

However, without certification, many employed to protect data and networks will find that their opportunities for advancement can come to a grinding halt without obtaining ISC2 certifications. Many reach out and contact for help with becoming CISSP certified.

What Is CISSP?

Certified Information Systems Security Professional, or CISSP for short, is a certification given by the International Information Security Certification Consortium. The world’s largest IT security organization, the ISC2, is a nonprofit that issues cybersecurity certifications and has developed what they refer to as the Common Body of Knowledge. The CISSP CBK is a collection of topics relevant to cybersecurity.

To obtain CISSP certification, a candidate must prove knowledge of the CISSP’s eight domains. This is achieved by passing the challenging CISSP exam. The ISC2’s prerequisites for the exam are that candidates must have a four-year college degree or the regional equivalent if outside of the United States. Also required are five years of paid employment, focusing on at least two of the CISSP’s eight domains.

What Are the Core Concepts of CISSP?

The core concepts of the CISSP encompass its eight domains. Candidates seeking CISSP certification are typically those who want a balance of managerial duties along with technical duties. The CISSP exam covers a lot of territory from a management and technical perspective.

One of the most important core concepts of the CISSP is the Security and Risk Management domain. This domain comprises 15% of the CISSP exam and is the most expansive. Concepts include data integrity, security, confidentiality, and the importance of legal and regulatory issues. Another core concept of this domain is the establishment of security policies and procedures.

Security Assets, the second domain of the CISSP, focuses on establishing safe and secure assets retention and identifying assets. Protecting the privacy of data is also core to this domain.

The sixth domain, Security and Testing, deals with designing, testing, and auditing IT systems and processes. This domain addresses software vulnerabilities and develops testing strategies to prevent them.

How Is It Possible to Have Knowledge of All 8 Domains?

To become CISSP-certified, a candidate must have a good understanding of all eight domains. The topic is dense and far-reaching, and at first thought, it may seem incredibly daunting. However, more than 156,000 worldwide have this respected certification, so it is definitely attainable.

You’ll need to devote at least three months of study time before attempting to take the exam. There are books and study guides that can be purchased that can help you achieve your goal, but the best course of action is to take an online CISSP masterclass.

The most helpful masterclasses provide you with not only study materials, video presentations, and explanations of the eight domains but also one-on-one video calls with highly knowledgeable mentors. These personalized meetings can help to point out your weaknesses and how to overcome them.

CISSP masterclasses will also provide you with sample tests that mimic the Computerized Adaptive Testing (CAT) format that the actual exam uses. This algorithm-based exam will determine the test taker’s next question on those already answered incorrectly. Taking a masterclass sample exam multiple times will help to indicate where a candidate needs to focus their studies.

Demystifying CISSP: The Bottom Line

The most natural progression from cybersecurity employee to cybersecurity expert is by putting in the time and effort to obtain CISSP certification. Although the exam requires extensive knowledge of the CISSP’s eight domains, this well-respected certification can be obtained with the proper amount of preparation. Once certified, you’ll be able to advance in your career much more easily.

Putting in as much effort as possible when studying for the exam is highly recommended. CISSP online masterclasses have proven to be a very effective way to prepare for this difficult but achievable certification.
