The CISSP certification certifies IT security professionals and validates their competency. The International Information System Security Certification Consortium ISC2 is the authority for issuing this certification. 

It also created a Body of Knowledge (CBK) to include all the information that expert cybersecurity professionals need to know. According to a Workforce Study, employers expect 72% of cybersecurity professionals to acquire specialized certifications. 

CISSP-certified professionals have great earning potential. The average salary for CISSP-certified professionals is $140,000. Employers will know you are a top security professional if they see CISSP certification in your resume. 

CISSP-certified professionals must maintain the certification, showing their employers they are committed to continuous learning. It will help you acquire subject expertise and gain a deeper knowledge of cybersecurity topics. Your CISSP certification will also qualify you to become an (ISC)²  member, and you can network with other (ISC)²  professionals.

As a continuous commitment to the members of (ISC)², the consortium conducts Job Task Analysis (JTA) to ensure the relevancy of CISSP. The results of the study are used to update the examination. 

This is important to ensure that the candidates who take the CISSP exam are tested in the latest and relevant subjects corresponding to the updated job roles and responsibilities in the cybersecurity industry. 

The competencies of the candidates are tested on 8 different CISSP domains. 

Below is the CISSP domains list:

1. Security and Risk Management

This domain explores all the basic security control frameworks and governance principles. The exam questions will test you based on ISO 27001, 27002, COBIT, Cloud Security Alliance’s CSA Start framework, etc. You must also learn about the CIA security principle that ensures confidentiality, integrity, and availability. This explores security methodologies to keep data private and stop unauthorized modifications while ensuring availability. 

Candidates will also learn about security governance fundamentals and management. It also identifies and quantifies threats based on risk levels and business continuity requirements. As a part of governance, establishing procedures, standards, principles, policies, and guidelines is also important, and cybersecurity professionals should learn about it. 

2. Asset Security

This domain dives deep into digital assets, identification, classification, and ownership. Cybersecurity professionals need a complete understanding of the existing digital assets. You must learn data security controls, handling, labeling, and secure data storage procedures. Understanding data retention and privacy is also important for ensuring asset security. 

3. Security Architecture and Engineering

This domain covers security design principles and models. Security architecture is an important aspect of cybersecurity that governs access control and security assessment. The security architecture varies based on the enterprise IT environment. Different methodologies are necessary for web-based, cloud-based, mobile, IoT, and embedded systems. 

Security professionals must know about security vulnerabilities and their relevance in real-world situations. This domain also covers physical security principles that physically protect the facility, its design, and operations. 

4. Communications and Network Security

In this domain, candidates will learn about secure network architecture design. Different network protocols, like OSI and TCP/IP, have different security needs. While learning about communications and network security, you will learn about Wi-Fi protection, instruction detection and prevention systems, network access control, and endpoint security. 

After covering this domain, candidates can design secure communication channels. They will also learn virtualized network technologies from basic VLANs to advanced Software-Defined Networking (SDN) networks. You also must have a good understanding of basic network protection techniques. 

5. Identity and Access Management

Cybersecurity professionals must know how to manage and use user identities for user authentication. Enterprises expect security experts to control asset access, including systems, devices, and files. Security professionals must determine and establish directories and database permissions. The physical security of facilities should never be ignored. 

Several tools are available to implement Identity and Access Management (IAM). They must know authentication policies like Multi-Factor Authentication (MFA) and Single Sign On (SSO). The security team is responsible for granting privileges and access controls for multiple enterprise systems. 

By learning this domain, you will understand cloud-based identity services, registering and managing identity information, identity provisioning, access reviews, and requests. 

6. Security Assessment and Testing

Those who want to work in the cybersecurity industry must know assessment and testing to identify security availability. You will learn about security controls, operations, and management in this domain. Cybersecurity individuals must know the basics of security control testing. Penetration testing is one of the advanced cybersecurity concepts where you will do port and vulnerability scanning to break into software and systems. 

This domain also explores multiple ways to review logs and application source code to uncover vulnerabilities. The testing methods will enable you to test the enterprise systems for security and resilience. You must also learn to design security audits to understand the enterprise’s security architecture accurately. 

7. Security Operations

You will explore all the CISSP concepts from an operational perspective in this domain. You will learn how to implement day-to-day security operations like investigations, incident management, and disaster recovery. You will learn essential concepts like security information and event management (SIEM), intrusion detection, and prevention. 

Reviewing security logs will only shed light on security events. Cybersecurity professionals must also know incident management operations like detection, investigation, response, mitigation, and reporting. They must also know secure resource allocation, protection, and monitoring for completing enterprise tasks. To ensure business continuity, you must learn disaster recovery strategies, personal management, communications, and disaster recovery. 

8. Software Development Security

Professionals involved in cybersecurity must also learn how to implement security in software development. To create appropriate security standards, you must learn waterfall and agile development cycles and software maturity models.

7 Tips for Mastering 8 CISSP Domains

Acquiring CISSP certification is rewarding in terms of better job prospects and higher salaries. However, passing the examination on the first attempt is difficult. 

Following are some tips that can help you to master ISC2 CISSP domains:

1. Understand exam outline and details and ensure you have the latest information on domain topics
2. Create a customized study plan after reflecting on your strengths and weaknesses
3. Sign up for a CISSP preparatory course and soak up knowledge shared by mentors and tutors
4. Take as many practice exams as possible
5. Join online communities and forums and discuss cybersecurity operations
6. Use multiple resources to study for the exam
7. Create a detailed plan for exam day

Passing Criteria for the CISSP Exam

To get CISSP certification, you must score at least 700 out of 1000 marks. Passing the CISSP exam on your first attempt requires a great deal of preparation and training. If you don’t clear the exam the first time, you can make multiple attempts after waiting for 30 days after the first time. You can take the exam a maximum of four times a year. 

Do You Need to Pass All the CISSP Domains?

To increase your chance of passing the exam, you have to be proficient in all CISSP security domains. During the exam, you have to reach a level of proficiency in each domain. 

The CISSP exam domains have different weightage. Some of the questions are pre-test questions designed to qualify you for future exams. However, candidates will not know the difference between pre-test and actual scored questions. ISC2 takes these measures to ensure that only competent professionals qualify for certification. 

So, you don’t have to reach 70% in each domain, but you must obtain a weighted score of 700 after answering all domains. At the same time, it doesn’t meant that you can pass the exam after getting all the answers wrong in a domain. The aim of CISSP test is to ensure that you are proficient in all of the CISSP domains. 

CISSP Certification Cost and Renewal Policy
