Explain the risks and implications of unauthorised access with an illustrative example.

Answer

Unauthorised access means using computer hardware without permission. This access can be used to manipulate system settings and data, and the implications of this act could be very harmful for an individual or an organisation.

Risks and implications of unauthorised access:

• Privacy: It may be an attack on the privacy of a user or organisation. An unauthorised person can access personal information like contacts, data, and the history of a person.

• Security: The unauthorised access to hardware may result in security issues. The websites or networks used by that unauthorised access may be susceptible to different security concerns, like hackers attacking your hardware through those sites.

Example: If a person uses someone else’s computer in a public place without permission and accesses files or browses websites, it is an example of unauthorised access. This may expose the system to malicious websites or allow the person to misuse personal data stored on the computer.
