A recent Ponemon Institute study finds that small and mid-sized businesses continue to be targeted by cybercriminals, and are struggling to direct an appropriate amount of resources to combat the attacks.

The Ponemon study finds that 76 percent of the 592 companies surveyed had experienced a cyber-attack in the previous year, up from 70 percent last year. Phishing and social engineering attacks and scams were the most common form of attack reported by 57 percent of the companies,  while 44 percent of those surveyed said the attack came through a malicious website that a user accessed. I attended a meeting of Chief Information Security Officers this week and was shocked at one statistic that was discussed—that a large company filters 97 percent of the email that is directed at its employees every day. That means that only 3 percent of all email that is addressed to users in a company is legitimate business.

A recent Accenture report shows that 43 percent of all cyber-attacks are aimed at small businesses, but only 14 percent of them are prepared to respond. Business insurance company Hiscox estimates that the average cost of a cyber-attack for small companies is $200,000, and that 60 percent of those companies go out of business within six months of the attack.

These statistics confirm what we all know: cyber-attackers are targeting the lowest hanging fruit—small to mid-sized businesses, and municipalities and other governmental entities that are known to have limited resources to invest in cybersecurity defensive tools. Small and mid-sized businesses that cannot devote sufficient resources to protecting their systems and data may wish to consider other ways to limit risk, including prohibiting employees from accessing websites or emails for personal reasons during working hours. This may sound Draconian, but employees are putting companies at risk by surfing the web while at work and clicking on malicious emails that promise free merchandise. Stopping risky digital behavior is no different than prohibiting other forms of risky behavior in the working environment—we’ve just never thought of it this way before.

Up to this point, employers have allowed employees to access their personal phones, emails and websites during working hours. This has contributed to the crisis we now face, with companies often being attacked as a result of their employees’ behavior. No matter how much money is devoted to securing the perimeter, firewalls, spam filters or black listing, employees still cause a large majority of security incidents or breaches because they click on malicious websites or are duped into clicking on a malicious email. We have to figure out how employees can do their jobs while also protecting their employers.
