It's an unfortunate fact of life that on an almost daily basis we read about the latest organisation crippled by a cyber-attack. 

We often hear about how the "bad guys" use clever techniques to evade IT security systems: dropping malware through a phishing email, 'man in the middle' data interception, or denial-of-service attacks that cause disruption. 

The list goes on. But too often human error is to blame.

A recent data breach by the Swedish government exposed the names, photos and home addresses of millions of Swedish citizens, including air force fighter pilots, members of the military's most secretive units, police suspects, people under witness relocation programmes, the weight capacity of all roads and bridges, and much more.

The incident is believed to be one of the worst government information security disasters ever.

This data leak shows that no matter how much organisations spend on IT security systems to protect their assets and data they will always be vulnerable unless employees are educated on how to handle sensitive data correctly.
