More than one in five (22 percent) of Brits have lost a mobile phone at some point, says Sophos, while a further 12 percent have had a handset stolen. 

Research commissioned by the security firm also revealed 12 percent have had a handset stolen. However, despite this, more than two thirds (67 percent) admitted they don't use a password to protect data stored on their mobile phone.

Furthermore, while six in 10 survey respondents acknowledged theft or loss was the biggest security threats to mobile device security, just over half (57 percent) said their mobile devices are password-protected and 18 percent admit to using the same password for everything.

"More and more people are using personal laptops, smartphones and tablets when they're working remotely. While this helps to improve productivity and innovation in a business, it is essential to address the security and operational issues relating to mobile devices now, rather than getting caught out later," said James Lyne, director of technology strategy at Sophos.

"If an employee's unprotected personal laptop falls into the wrong hands, it can be easy for someone to access not just personal information, but any work related documents saved on the laptop's hard drive, or even to use the laptop as a way to gain access to the corporate network."

In a bid to help businesses educate their employees on the threats associated with mobile technology, Sophos has launched a free mobile security toolkit containing top tips for users for creating secure passcodes, a user-targeted video and presentation, whitepapers and a sample security policy.

"Most data breaches on mobile devices are typically due to basic security failures such as weak or no passwords being in place, failure to encrypt data or falling victim to phishing or other social engineering attacks," said Lyne.

"If devices are used for business, it's important that IT teams get the basics under control. By making sure that they can purge devices when they go missing, businesses can both minimise the risk of data loss and can also satisfy regulators."

The Sophos Mobile Toolkit can be downloaded for free from the company's dedicated web page.
