The Culture, Media and Sport Committee has announced it is to launch an official inquiry into the standards of cyber security on the back of the recent high-profile attack on TalkTalk.
The attack had initially sparked fears that the personal details, including bank details, of over four million customers had been hacked and made public.
Concerns have since grown, with officials keen to examine how companies store and secure customer information, with TalkTalk attracting particularly strong interest.
The company had already suffered two previous attacks this year and the Committee is keen to look at a number of areas, including the nature of the cyber attacks on the company's website and its subsequent response.
It is also set to look at the robustness of measures that providers in the telecoms and internet industry are putting in place to maintain the security of customer information, including levels of investment.
The nature and role of encryption in protecting personal data will also be examined, as well as any potential future trends in hacking, technology and security.
The Committee states it expects to hear evidence for this inquiry late November.
Its Chair, Jesse Norman MP, said: "The recent events have highlighted serious issues relating both to existing cyber-security and the response to cyber-crime.
"This Committee is concerned with the attacks on TalkTalk specifically as a telecoms and internet service provider, but with the recent move of the Information Commissioner’s Office to DCMS, we will also be looking more widely at the security of personal information online."
