Amazingly, email has been around in one form or another for nearly 50 years – but is it finally past its sell-by date? As far as cyber crime goes, it is an unlocked door or unattended handbag; offering an irresistible opportunity to any light-fingered passer-by. Some would argue it is also a huge corporate timewaster. And yet more than two and a half billion people around the world use email services on a daily basis.
Researchers are working hard on finding workable alternatives. Unfortunately, as with most security issues, the real problem is human beings – particularly the ones who open dodgy files and click on dubious links. However good a new messaging system is, it will always be vulnerable to attackers preying on the gullible. Maybe the scientists should really be concentrating on producing a new and improved human brain? Fact is, whilst lack of awareness, curiosity and simple human error persist, social engineering, phishing and malware will remain extremely successful means of gaining access to valuable data – both at an individual and corporate level.
