Cloud computing technology is fast becoming an attractive alternative to maintaining IT systems and applications on premise. In-house management and maintenance of IT is costly and resource-hungry. Small and medium-sized businesses in particular benefit from the way cloud services give them access to greater processing power and IT expertise than they could ever aspire to with the modest budgets and resources of their own. Cloud computing also provides an opportunity for large organizations to enjoy economies of scale for the high data volumes produced by the many and various devices, operating systems and applications they use.
Wi-Fi hotspots in coffee shops, hotels, railway stations and airports have become a welcome resource for any business traveler, providing them with a convenient means to carry on working while on the move. Employers, in turn, are increasingly happy to embrace the accompanying productivity benefits. Over 80% of enterprises now allow employees to use personal devices to connect to corporate networks.
Yet public Wi-Fi has a dubious security reputation. Even with password protection, public hotspots are an open invitation for anyone with illicit intentions to snoop and intercept data communications to their heart’s content.
Ransomware is the latest trend in criminal malware. It infects computers, encrypts data and demands a ransom payment in the form of bitcoins. The encryption is so strong that it has not yet been circumvented. Locky and other ransomware have the potential to become much more than an annoyance.
Recently one case was reported where patient data was encrypted at a hospital. That might seem bad enough but what would happen if computers that control medical devices are infected by the virus and they show a ransom letter instead of doing their job? Documents, photographs, films and other personal data are usually the prime targets for encryption rather than system files and applications. However, databases and license key files have also fallen victim to unauthorized encryption.
