China and the US have finished a high level cyber security dialogue.
Challenges in the world of online security remain, as cyber security expert and author of "Virtual Terror" Daniel Wagner told CGTN.
He said that one of the main obstacles to catching cyber criminals is the fact that there are no international laws governing cyber space.
This makes it easier for criminals to use international borders to evade justice. International terrorist groups such as ISIL can hide behind the anonymity afforded by the Internet to organize and recruit.
As ISIL loses physical territory in Iraq and Syria, it is increasingly utilizing the Internet for its work.
Wagner said the nameless nature of the Internet makes it very difficult for the US to determine who is responsible for the attacks on the computers at the Democratic Party offices last year.
Several investigations have been launched into the theft of emails from the computers, but Wagner says they're unlikely to identify a culprit.
He warned that anyone with a laptop or a smartphone can become a victim of cyber crime. But he added that a few, simple steps can help prevent that. He advised everyone to change their passwords frequently and use two-party verification whenever possible.
