Small business retail advice on how to reduce the opportunity of ransomware attack

Ransomware / malware can come in many forms. Every computer connected to a network in any way is at risk. There is no guaranteed protection but there are important steps a business can take. This advice provides advice designed to reduce the risk to your business.

Here is best-practice advice from our POS software company for local small business retailers on ways to protect against Ransomware:

1. Ensure you use professional, up to date, virus protection.
2. Ensure you have a good firewall with strong settings.
3. Do not click on emails or attachments unless you are sure of the sender.
   1. Be particularly wary of ZIP files in emails.
   2. The ATO will not email you.
   3. Your bank will not email you.
   4. Australia Post will not email you, not like the example I have posted.
4. Ensure all passwords you use are strong.
5. Consider using an email filtering facility.
6. Do not allow remote access to your computer unless you are certain of the person accessing.
7. Ensure you have strong passwords. A strong password should include: some CAPS, some numbers and at least one special character. Check your password at: https://howsecureismypassword.net
8. Change your password regularly.
9. Run an up to date operating system.
10. Have rules on computer use: no games, no online gambling, no porn, no personal emails.
11. Have an overarching rule: do not open any email or go to any website unless you are certain.
12. Use a cloud backup service like the Tower backup service. This provides the fastest recovery.
13. Have multiple backup devices for additional protection.
14. Do not use automatic file replication programs / facilities such as Dropbox or Google Drive. If a file is encrypted with malware / ransomware it will upload to the account and infect other files.

Most ransomware attacks can be avoided by careful scrutiny of your emails and websites you visit.
