Abstract
"Access" is defined in Section 2(1)(a) of the Information Technology Act as "gaining entry into, instructing or communicating with the logical, arithmetical, or memory function resources of a computer, computer system or computer network". Unauthorised access would therefore mean any kind of access without the permission of either the rightful owner or the person in charge of a computer, computer system or computer network. Thus not only would accessing a server by cracking its password authentication system be unauthorised access, switching on a computer system without the permission of the person in charge of such a computer system would also be unauthorised access.
