Dr. Pavan Duggal, acknowledged as one of the top four Cyber Lawyers in the world, gave a definition of Cyber law , which is broadly accepted, as follows: –

Simply speaking, Cyber law is a generic term, which refers to all the legal and regulatory aspects of Internet and the World Wide Web. Anything concerned with or related to or emanating from any legal aspects or issues concerning any activity of netizens and others, in Cyberspace comes within the ambit of Cyber law.

According to Wikipedia, Cyber Law or Internet law is a term that encapsulates the legal issues related to use of the Internet. It is less a distinct field of law than intellectual property or contract law, as it is a domain covering many areas of law and regulation. Some leading topics include internet access and usage, privacy, freedom of expression, and jurisdiction.

Cyber law is important because it touches almost all aspects of transactions and activities concerning the Internet, the World Wide Web and Cyberspace.

Cyberlaw concerns everyone. Cyberlaw is a constantly evolving process. As the nature and scope of Internet is changing and this new medium is being seen as the ultimate medium ever evolved in human history, every activity of yours in cyberspace can and will have a cyber legal perspective.
