Andrew Parker, the head of MI5, U.K.'s home security agency, warned of the terror risk that our technological advancements are opening up, according to BBC News. Parker claims that these advancements are making terrorist communication easier to do without alerting authorities.

"It's in nobody's interests that terrorists should be able to plot and communicate out of the reach of authorities," he said.

Parker believes that the matter of increased surveillance is in the hands of parliament and any legislative changes are up to them, according to The Economic Times.

"It is completely for ministers to propose, and Parliament to decide," he said. "It's a fundamental point about what MI5 is. It's for us to follow what's set by Parliament."

Parker also brought up the role of companies like Facebook and Twitter in communicating with authorities when they have access to information about terrorism and other criminal activity.

"The way we work these days has changed as technology has advanced," he said. "Our success depends on us and our partner agencies having sufficient up-to-date capabilities, used within a clear framework of law against those who threaten this country."

Despite Parker's desires, many sites now utilize encryption services so complex that it makes it much easier for authorities to lose track of any potential criminals or criminal activity, according to The Telegraph.
