The group is due to present the results of its investigation into the 1990 Computer Misuse Act. Businesses have complained that the Act is out of date and contains loopholes that could make it difficult to bring prosecutions against those responsible for some forms of denial of service attack.
The MPs began their inquiry following a campaign by Computer Weekly. Their conclusions will play a critical role in plans by the Home Office to update the UK's computer crime laws.
E-crime minister Caroline Flint announced last year that the government would strengthen the Computer Misuse Act as soon as Parliamentary time was available.
