5 cybersecurity tips that businesses can action now.
How to protect your business against the growing threat of cyberattacks.
Over the past year or so, you’ve probably heard about some of the high profile cyberattacks to hit New Zealand.
Think Waikato DHB, where sensitive patient information was held captive by hackers. Or the New Zealand Stock Exchange being brought to a standstill by a cyberattack that saw large numbers of computers connect to an online service at the same time.
Unfortunately, these publicised attacks are just the tip of a growing iceberg. Last year there were over 8,831 cyberattacks reported to CERT NZ, costing companies around $16.8m. And it’s not just big organisations that are at risk. Small and medium-sized businesses are vulnerable too.
With that in mind, we wanted to share a few tips that any business can put into action:
1. Know what’s coming
The best defence is knowing the most common forms of cyberattack.
Malware is an umbrella term for malicious software that aims to damage your computer, server, network or client.
Viruses and ransomware are considered types of malware. Viruses infect your computer as well as other devices, leaving your system vulnerable. Ransomware works like a virus, but is usually delivered through a phishing email and essentially holds your system hostage until a sum is paid. (Ouch)
Phishing is a type of scam that tricks people into clicking links that appear legitimate but are malicious. Clicking the link infects your device with malware. Once your system is infected, cybercriminals can attempt to steal sensitive information.
2. The all-important human factor
Train employees to be security-conscious.
Cybersecurity is a team effort. Make sure your employees create strong passwords and reset them on a regular schedule. Employees should be aware of red flags that indicate phishing emails and malicious files, as well as have an action plan if an attack happens. It’s also important to keep devices, software and browsers up to date.
3. Secure your Wi-Fi network
If your business WiFi is popping up for all to see, it shouldn’t be!
It’s best practice for your business WiFi to stay secure, encrypted and hidden. The business router needs to be password protected, and it shouldn't broadcast the network name. If your business is being run from home, consider whether it's time to upgrade your router to handle modern security threats.
4. Back up your files
Make sure you have another copy of your data.
Cyberattacks aim to compromise, delete or steal your data. Backup programs can help mitigate this risk. For bonus points use backup software that lets you set up a schedule or automate backups. Keep a copy of your backups offline in case of a cyberattack.
5. Use antivirus software
Technology can give you a helping hand.
Finding the right antivirus software is an important weapon in the defence against cybercrime. Antivirus software doesn't have to break your bank either – for example, Microsoft Defender is free for Windows.
