In the blog post Dr Michalas notes that the most common issues in security software come from human errors and emphasises on the fact that a large per cent of cyber-attacks are also carried out or mediated by insiders. Referring to the WannaCry case, Dr Michalas says that its impact would have been much smaller if NHS employees were properly prepared, as security awareness is a key factor for ransomware prevention.
Dr Antonis Michalas also points out the fact that the healthcare industry is a big target for cybercriminals because the data they hold can be sold to medical insurance companies for a significant amounts of money.
Finally, Dr Michalas notes that secret services can also pose a real threat to cyber security, mentioning that a wide array of malicious tools designed by the NSA to infect and control computers have been leaked by hackers.
“While security services need to enjoy the power to access everybody’s computers so as to avert/investigate crime, they also have a responsibility to ensure that such technology is isolated securely so that it does not get into the wrong hands.”
