Nila Ltd. relies on its information system for customer records. An employee deliberately alters stored customer data without permission, using a valid login belonging to a colleague. Which pairing correctly identifies the information security property compromised and the relevant legal position under the Information Technology Act, 2000?

Integrity is compromised because stored data was changed without authority. The Information Technology Act, 2000 attaches liability to unauthorised access and to damaging or altering computer data, and using a colleague's valid login does not make the access authorised.

  1. AAvailability compromised; no offence arises because the login was valid
  2. BConfidentiality compromised only; the Act does not cover alteration of data
  3. CIntegrity compromised; unauthorised access and damage to computer data can attract liability under the ActCorrect
  4. DNon-repudiation compromised; liability arises only if the data is printed

Explanation

Unauthorised alteration of data breaks integrity, since data is no longer accurate and reliable. The IT Act penalises accessing a computer without permission and damaging or altering data, and use of another's credentials does not make access authorised. Option A wrongly treats a valid borrowed login as permission.
