Business Administration:
Business administration involves the management and coordination of various aspects of a business, such as finance, marketing, and operations. Cybersecurity is the practice of protecting an organization’s networks, systems, and data from cyber threats and attacks. Business administrators must be aware of the importance of cybersecurity and take steps to protect their organization’s assets, such as by implementing policies and procedures for data security and incident response. Additionally, as cyber threats and attacks are becoming more sophisticated and frequent, business administrators may need to work closely with cybersecurity experts to ensure that their organization is protected from these threats.

Computational and applied mathematics:
Computational and applied mathematics plays a critical role in cybersecurity. The field of cybersecurity requires the use of advanced mathematical techniques to protect and defend against cyber threats, such as encryption and decryption, data analysis, and risk assessment. Encryption is the process of converting plaintext into an unreadable format to prevent unauthorized access to sensitive information. This is typically achieved through the use of mathematical algorithms such as RSA and Elliptic Curve Cryptography, which are based on number theory and abstract algebra. Data analysis techniques such as machine learning, statistics and data mining are used to identify patterns and anomalies in large datasets that can indicate a cyber-attack. These techniques rely on mathematical modeling, optimization, and numerical simulations.

Computer Engineering:
Computer engineers play a crucial role in cybersecurity by designing and developing secure systems and networks. They apply their knowledge of computer systems and networks to identify and mitigate potential security vulnerabilities in the hardware and software. They also design and implement security protocols and standards, such as firewalls, intrusion detection systems, and encryption algorithms to protect the systems and networks from unauthorized access and attack.

Information Systems & Technology:
Information systems and technology professionals play a crucial role in cybersecurity by designing and developing secure information systems and networks. They apply their knowledge of IT to identify and mitigate potential security vulnerabilities in the systems and networks. They also design and implement security protocols and standards, such as firewalls, intrusion detection systems, and encryption algorithms to protect the systems and networks from unauthorized access and attack. Additionally, IS&T professionals work closely with cybersecurity experts to design and develop new technologies and tools that can detect and respond to cyber-attacks, such as intrusion detection systems and incident response systems.
