On the back of the Waikato DHB being held ransom it's timely to remind ourselves that ransomware attacks can cause huge disruptions to your business, including loss of income, customer trust and resources. See the simple steps you can take to protect your business from a ransomware attack and how to react if you’re targeted.
Be aware of phishing campaigns. Phishing is a common way that computers and systems get infected. Learn how to spot dodgy emails, websites or links that could be harbouring malicious software. If you have staff, talk to them to make sure they’re aware of the risks as well.
Regularly install updates on software and devices. This will prevent attackers from exploiting vulnerabilities which they could use to get into your systems.
Implement two-factor authentication. Two-factor authentication is usually a code that’s sent to your phone or an authentication app to verify your identity. This is used in addition to a password and adds another layer of security to your logins.
Back up your business and customer data. This way if your data is lost or stolen, you can recover it quickly. You can back it up on an external hard drive or on a cloud service.
Talk to your IT team or service provider about setting up logs. They record when particular actions are taken on your website and systems and who’s done them. You’ll then be notified if any unusual or unexpected activity occurs.
Have an incident response plan. No matter how well you prepare and how good your cyber security is, things can still get through the cracks. Have a plan that will help you take control of the situation if the worst were to happen. Know who to call and prepare by doing things like making hard copies of all important documentation in case you can’t access your system.
