WFH Spells Security Concerns, Experts Say

With more employees working from home now, and possibly beyond the COVID-19 pandemic, home network security is a growing concern, experts told a webinar with cybersecurity company Bitdefender. Nearly 80% of U.S. consumers surveyed by Parks Associates are concerned about a data security break or privacy issues, said analyst Brad Russell. The increasing time households are spending on their Wi-Fi networks heightened home network exposure to phishing attacks, Russell noted. WFH puts the home network “in a completely different spotlight,” said Alex Balan, Bitdefender chief security researcher. Bitdefender is tracking 350 IoT-oriented botnets in its labs that are compromising such smart home devices as routers, power outlets, smart cameras, printers, smart TVs and connected coffee makers. Eventually, all devices in the home will be connected and the number of attacks on home networks will “dramatically expand,” said Balan. Vulnerabilities are present in 90% of the devices Bitdefender analyzes, he said, and are “very difficult to defend against.” Consumers can’t buy anti-virus software “for a smart light bulb or a Roomba,” he said. “You don’t know how to tackle security for your smart devices.” The average broadband household has 22 devices, up from 12-15 two years ago, said Razvan Todor, Bitdefender director-connected home security, and that will keep growing. “We’ve just now become painfully aware that we need to protect them,” ideally from a single point, said Todor. ISPs can help with cybersecurity, while clearing up their networks with fewer distributed denial-of-service attacks, experts said.
