Large-scale cyberattacks with eye-watering statistics, like the breach of a billion Yahoo accounts in 2016, grab most of the headlines. But what often gets lost in the noise is how often small and medium-sized organizations find themselves under attack.
In the last year, half of American small businesses have been breached by hackers. That includes Meridian Health in Muncie, Indiana, where 1,200 workers’ W-2 forms were stolen when an employee was duped by an email purporting to come from a top company executive. Many small companies are just one fraudulent wire transfer away from going out of business.
There’s lots of advice available about how to fight cybercrime, but it’s hard to tell what’s best. I am a scholar of how businesses can more effectively mitigate cyber risk, and my advice is to know the three “B’s” of cybersecurity: Be aware, be organized and be proactive.
Here’s how more companies can boost their cybersecurity preparedness without breaking the bank.
Almost any company can be vulnerable to a range of cyberattacks. A company manager or network security professional needs to know about the various types of digital threats and how to limit vulnerability.
There are some attacks that every employee should know about. The most common attacks use a method called “phishing,” or a variant that specifically targets one potential victim, called “spearphishing.” These typically take the form of email messages that appear to be sent by coworkers or supervisors asking for sensitive information. That’s what happened to the health care company in Muncie. These messages can contain instructions that a victim might follow, believing them legitimate – such as clicking a link that installs malware or captures login information, or even making a wire transfer to another business’s account.
The best defenses against these types of attacks involve skepticism and vigilance. Attackers can be very clever and persistent: If just one person has one weak moment and clicks on one malicious link, an entire network can be compromised.
Most companies go to great lengths to protect their physical assets and personnel. But many do not take similar precautions with their digital information. A key computer may be kept disconnected from the internet, but if it accepts flash drives or rewriteable CDs, or if its password is easy to guess, the information is just as vulnerable.
Small business owners need to prioritize cybersecurity. Without proper preparation, even large companies can find themselves unprepared for cyberattacks. When Sony was hacked in 2011, it did not have an executive focused solely on information security. But hiring someone did not prevent another hack in 2014.
