Hackers are targeting security vulnerabilities via remote users logged into companies' virtual private networks (VPNs), security experts have warned.
Mike Jones, senior product manager at Network Associates (NAI), said the growth in DSL services for remote workers will bring new risks. "A hacker gets into a remote user's PC and then into the corporate network. These always-on systems are vulnerable to scans. Our research shows that ports are scanned up to five times a day," said Jones.
Neil Barrett, security consultant at analyst IRM, said VPNs attracted the attention of hackers because of the ease of mobile access. He said encryption products should be applied throughout VPNs. "If the client and firewall are protected, companies will find that they have a secure connection."
Jones said NAI's new release, PGP7, contains software which addresses this issue.
