Cybersecurity refers to a set of technologies, practices and processes designed to protect computer systems, networks, electronic devices, programs and digital data from attack, theft, damage, or unauthorized access. Cybersecurity has been viewed from various perspectives such as organizational, economic, social, political and other perspectives that are inextricably tied to cybersecurity efforts. The International Telecommunication Union (ITU) defines cybersecurity as:

“The collection of tools, policies, security concepts, guidelines, risk management approaches, actions, training, best practices, assurance and technologies that can be used to protect the cyber environment and organization and user’s assets. Cybersecurity strives to ensure the attainment and maintenance of the security properties of the organization and user’s assets against relevant security risks in the cyber environment.” 

Cybersecurity involves a range of measures such as firewalls, encryption, multi-factor authentication, intrusion detection systems, and vulnerability assessments, among others. 
The aim of Cybersecurity is to safeguard digital data and ensure the integrity, confidentiality, and availability of information systems and their resources. It is an essential aspect of modern-day technology, given the increasing dependence on digital systems and the threat of cyber-attacks.
