Answer: C – Goals
The first dimension of the cybersecurity cube identifies the Security Goals or objectives that are required to protect the information within cyberspace. It focuses on principles of confidentiality, integrity and availability. This is also called the CIA Triad.
Detailed Explanation
What is a Cybersecurity Cube?
Also known as the McCumber Cube, it is a comprehensive framework to guide and evaluate different aspects of information security programs. The conceptual model presents a three-dimensional approach to cybersecurity.
What are the Three Dimensions of the Cybersecurity Cube?
Each dimension of the cybersecurity cube addresses critical aspects of information security and understanding these dimensions is crucial to implement effective strategies for heightened security.
First Dimension: Security Principles or Security Goals
The first dimension of the cybersecurity cube focuses on the foundational goals that are crucial for protecting information security programs. The identified goals are classified as Confidentiality, Integrity and Availability; also called the CIA Triad. These principles provide focus and enable the specialists to prioritize security.
Second Dimension: Information States
The second dimension focuses on different states in which information is stored in a system. The cybersecurity specialist uses the second dimension to protect data and implement appropriate measures that are tailored to all states of data in the cyber world. There are three possible states of data –Data at Rest (In storage), Data in Transit (Transmission), Data in Use (Processing).
Third Dimension: Security Measures
The third dimension of the cybersecurity cube focuses on the tools or powers used to safeguard the information in the cyber world in all states. These security measures are identified as –Technology, People and Policies and Practices.
By considering the three dimensions, the cybersecurity cube provides a comprehensive approach to address the multifaceted nature of information security.
What is the CIA Triad?
The first dimension of the Cybersecurity cube encapsulates the three principles, which serve as the foundational goals of any cybersecurity initiative to protect data. These principles are known as the CIA Triad. There are defined as mentioned below –
Confidentiality – The very first foundational goal ensures the protection of data by only allowing authorized individuals to access data. Confidentiality is maintained in the cybersecurity cube by implementing measures to prevent unauthorised access to protect data, safeguard privacy and proprietary information. They utilize different techniques like encryption, authentication protocols, and access controls to uphold confidentiality.
Integrity – Integrity refers to assuring that the information remains accurate, consistent, and trustworthy during the entire lifecycle. This ensures that the data has not been tampered or altered by an unauthorized entity intentionally or accidentally. To maintain the integrity of the information, measures to prevent unauthorized modification of data should be implemented and must ensure its reliability. To uphold integrity, hashing, checksums and digital signatures are employed.
Availability – The third principle of the Triad is Availability which ensures that the information and its resources are easily accessible by the authorized users, whenever needed. To maintain availability, preventive measures like correct system functioning and easy data access when needed should be implemented. The techniques used in the process are redundancy, failover mechanism and regular maintenance must be employed.
These three foundational goals aim to protect information from unauthorized access, prevent alteration, and ensure availability of the information to legitimate users.
