Nearly two-thirds of IT security professionals still rely on passwords to protect their corporate networks, despite growing numbers of people working remotely, new figures show.

While two-factor authentication is now considered a more secure solution, only 15 per cent of respondents said they used tokens to protect the remote access of mobile workers, according to the latest SafeNet survey.

Furthermore, only eight per cent used smart cards and three per cent employed biometric measures.

“Organisations trying to reap the benefits of mobile working, without adopting adequate security technology and processes are sitting on a security time bomb,” warned Gary Clark, vice president EMEA at SafeNet.

“Passwords have not been sufficient security for years now. They are too easily compromised. Employing layers of security, such as tokens and smart cards and granular authorisation, where network access is dependent on the worker’s location and position, is critical,” he added.
