Symantec Security Response has warned that a growing number of devices are becoming the focus of security threats as the IoT (Internet of Things) becomes a reality.
Potential security threats are very real, despite the IoT being in its early stages. One key example is a worm targeting computers running the Linux operating system that Symantec investigator Kaoru Hayashi recently discovered. The worm initially seemed nothing out of the ordinary - it leaves a back door on the infected computer, allowing the attacker to issue commands to it. Although computers are frequently patched, Hayashi found that devices such as home routers, set-top boxes, security cameras and industrial control systems were vulnerable as some vendors don’t supply updates, either because of hardware limitations or outdated technology, such as an inability to run newer versions of the software.
With the growth of Internet-enabled devices set to hit 50 billion by 2020, according to Cisco, these devices with the relative lack of security maybe one of the key targets of cyber attackers in the near future. Users of Internet-connected devices are strongly advised to follow the best practices listed below:-
