Cybersecurity is the body of knowledge that defines the guidelines, frameworks, policies, best practices, and measures to safeguard information technology assets in cyberspace. In a broader perspective, this is termed information security which encompasses the protection of both physical and logical information assets. Securing the computers from virus attacks are of bygone days. Both evolving technology and ever-increasing digitisation keep the security threat landscape always rattled. Machine learning and artificial intelligence continue to add new dimensions to both threat perception and defence mechanisms.

Cybersecurity breach is not limited to loss of critical information but extended to disruption of service, theft, money extortion, damage to enterprise reputation and even committing larger crime and conspiracy using the stolen data. Cyberspace is a new front of global warfare with all leading countries ready with a separate cyber warfare command centre to monitor, prevent and foil cybercrimes.
