CISSP (Certified Information Systems Security Professional) is a globally recognized certification in the field of information security. The CISSP certification is offered by the International Information System Security Certification Consortium, also known as (ISC)². The certification is intended for professionals who have experience in the field of information security and wish to demonstrate their knowledge and expertise in the field. Let’s see CISSP Cheat Sheet.
CISSP Cheat Sheet
The CISSP exam covers eight domains: Security and Risk Management, Asset Security, Security Architecture and Engineering, Communication and Network Security, Identity and Access Management, Security Assessment and Testing, Security Operations, and Software Development Security. The exam is 6 hours long and consists of 250 multiple-choice questions. The passing score is 700 out of 1000 points. The exam is offered in many languages and can be taken at various locations worldwide.
The CISSP Certification is highly valued in the field of information security and is recognized globally. It demonstrates a candidate’s expertise in the field and commitment to upholding high standards of ethics and professionalism. The certification is valid for three years, and certified professionals must earn continuing education credits to maintain their certification.
To be eligible for the CISSP exam, candidates must have a minimum of five years of professional experience in two or more of the CISSP domains. Alternatively, candidates can substitute a college degree or other professional certifications for some of the required experience. Once the exam is passed, candidates must also submit an endorsement from a current (ISC)² certified professional, along with a code of ethics agreement. See in details about CISSP cheat sheet.

- Security awareness training: Security awareness training is the process of educating employees and stakeholders about security risks and best practices.
Confidentiality – is the practice of preventing unauthorized disclosure of information. This involves the principle of “need to know” and “least privilege,” which ensure that only authorized personnel have access to confidential data. Other measures include encryption, logical and physical access control, and processes that safeguard against unauthorized disclosure.
Integrity – refers to the accuracy and consistency of data, ensuring that no unauthorized modifications are made. This principle ensures that data or resources are not altered in an unauthorized manner, protecting the authenticity and reliability of information.
Availability – ensures that information is reliably and timely accessible to authorized personnel. This requires fault-tolerance and recovery procedures that ensure that data is available when it’s needed.
IAAA – stands for Identification, Authentication, Accountability, and Authorization, which are essential requirements for security and accountability.
Identification – involves the user claiming their identity, which is then used to control user access.
Authentication – refers to the process of testing the evidence of a user’s identity, such as a username and password, to ensure that only authorized users can access data.
Accountability – refers to the practice of tracking and determining the actions of an individual person. This is essential in ensuring that individuals are held responsible for their actions, and it’s critical for auditing and compliance purposes.
Authorization – refers to the rights and permissions granted to an individual or group, which determines what actions they can perform within a system.
Privacy – refers to the level of confidentiality and protection that’s provided to personal information. This includes measures such as access control, data encryption, and other safeguards that prevent unauthorized disclosure of sensitive data.
Data Breaches: Data Breaches refer to incidents that have the potential to cause harm by compromising the confidentiality, integrity, or availability of personal or sensitive information. There are several key terms that are commonly used in the context of data breaches:
Incident: An event that has the potential to cause harm or disruption, such as a cyber-attack, natural disaster, or human error.
Breach: An incident that results in the unauthorized disclosure or potential disclosure of data. This can occur through a variety of means, including hacking, malware, social engineering, or physical theft.
Data Disclosure: The unauthorized acquisition of personal information, such as names, addresses, Social Security numbers, or credit card numbers.
Event: Threat events are accidental or intentional exploitations of vulnerabilities that can lead to data breaches. These can include software vulnerabilities, weak passwords, or inadequate security controls.
Goal: To determine the impact of a potential threat and assess the risk of it occurring. The main aim of risk management is to mitigate risk to a level that is considered acceptable.
Step 1: Preparation for Assessment
Prior to conducting the risk assessment, it is essential to prepare adequately by defining the purpose, scope, and other relevant factors. This step involves identifying the objectives of the assessment, outlining the scope of the analysis, and determining the level of detail required to evaluate the risk accurately. It is crucial to have a clear understanding of the purpose and scope of the assessment to ensure that all the necessary information is gathered and the appropriate level of analysis is conducted. By adequately preparing for the assessment, the risk management team can ensure that they are equipped to identify potential threats and evaluate their impact accurately.
Step 2 – Conduct Assessment
- ID threat sources and events
- ID vulnerabilities and predisposing conditions
- Determine likelihood of occurrence
- Determine magnitude of impact
- Determine risk
Step 3 – Communicate Risk/results
Step 4 – Maintaining Assessment and Identifying Types of Risks:
To effectively manage risks, it is important to understand the various types of risks involved. The following are the three types of risks that should be considered during the risk assessment process:
- Inherent Risk: This refers to the chance of making an error when there are no controls in place.
- Control Risk: This refers to the chance that controls in place will prevent, detect, or control errors.
- Residual Risk: This is the remaining risk after controls are in place.
In addition to these types of risks, it is important to consider business concerns about the potential effects of unforeseen circumstances. This combination of all risks is commonly known as audit risk.
To begin the risk analysis process, it is recommended to conduct a Preliminary Security Examination (PSE) to gather all the necessary elements needed for a thorough assessment.
The following steps should be taken during the risk analysis:
- Identify assets that need protection.
- Identify potential threats to those assets.
- Calculate the level of risk associated with those threats.
