"If you appear to be spending your holiday unsuccessfully attempting to separate your children from Wi-Fi or their digital devices, do not despair," Robert Hannigan, a former director of the Government Communications Headquarters, wrote in the British newspaper The Telegraph.
"Your poor parenting may be helping them and saving the country."
Hannigan, who left GCHQ at the start of this year, said parents are often scared of the virtual world because they don't understand it as their kids do.
"We need young people to explore this digital world just as they explore the physical world," he said, adding Britain is "desperately short" of cyber skills. "The baseline of understanding is too low and often behind our competitors."
Britain's parliament and National Health Service have been hit by cyber attacks in recent months, leaving lawmakers, their aides and hospitals locked out of their computer systems full of sensitive information.
In February, the government opened the National Cyber Security Centre - part of GCHQ - to help plug that gap.
Hannigan said it's not too late for parents to get involved too. He suggested they buy a Raspberry Pi, a small computer designed to help young people learn programming skills, and build it with their children.
"Leave aside your fears of being a nerd: that would be a problem to be proud of," he said.
