Abstract:
Organisations are constantly at risk from cyberattacks in today's digital environment, which can
seriously harm their finances, reputations, and operational capabilities. Organisations must take a
proactive approach to managing cybersecurity risk in order to protect sensitive data and systems. In
order to strengthen organisational security, this research study focuses on the ideas, methodology, and
best practises of cybersecurity risk assessment and management. The significance of comprehending the
threat landscape, doing risk assessments, putting risk mitigation techniques into practise, and creating
an all-encompassing cybersecurity management framework are discussed in the article. The results
emphasise the importance of a comprehensive and flexible strategy to cybersecurity that incorporates
technology solutions, personnel awareness and training, incident response planning, and ongoing
monitoring to maintain strong organisational security.
