Computer Misuse Act 1990
The Computer Misuse Act 1990 was passed to deal with a number of misuses as the use of computers became widespread.
The Act makes it an offence to:
- Deliberately plant or transfer viruses to a computer system to cause damage to programs and data.
- Use an organisation’s computer to carry out unauthorised work.
- Hack into someone else’s computer system with a view to seeing the information or altering it.
Problems with Gaining Prosecutions
- In order to prosecute someone the police would need to prove that they did the misuse deliberately.
- For example, if you had a virus on your flash drive from home and took it to work and put it into a computer and it transferred a virus, this is an easy thing to do unknowingly
- Some organisations would not want others to know that their security has been compromised; so many cases go unreported and unpunished.
Offences: Section 1

a) He/she causes a computer to perform any function with intent to secure access to any program or data held in any computer
