Senior Microsoft executives will today be questioned by the House of Lords Science and Technology Committee over the firm's steps to improve security on the internet.

The committee is holding an inquiry into personal internet security. It will this week hear evidence from senior executives Jerry Fishenden (Microsoft's national technology officer) and Matt Lambert (Microsoft's government affairs director).

The pair will be asked about steps the company has taken to protect its customers online as well as how the technology industry can do more to safeguard the public from internet-based criminals.

The committee will also ask the executives to explain Microsoft's record of co-operating with competitors to ensure internet users are protected.
