Research shows UK web users have become a lot more savvy about online security, but there is still a long way to go, says internet infrastructure firm VeriSign.
A survey by Ofcom has shown that 80% of respondents will restrict information published online to friends and family, up from 48% in 2007.
Most UK web users (82%) claim to be cautious when shopping online, according to a survey by VeriSign.
Despite the improvement, people are still being scammed, which shows there is a gap between awareness and practice, said Matthew Bruun, security expert at VeriSign.
"It is great that 80% of us are being careful online. But to create a safe society we need to shoot for 100%," he said.
UK web users need to be consistently aware of the havoc that cyber criminals can wreak with just a few pieces of your personal data, said Bruun.
Personal details such as date of birth, phone number and address provide a golden opportunity for cyber fraudsters, he said.
"With three pieces of information about you, a skilled criminal has a key to your 'blueprint' making it very easy for them to create a virtual identity with the potential to ruin your credit rating and reputation," said Bruun.
