1. Antivirus – Carefully choose your antivirus product, it is a major line of defence against infection. Look at www.av-comparatives.org for an unbiased comparison of the business products on the market. Bandicoot have opted for the #1 product, BitDefender which provides an excellent line of defence and also tightly integrates with our monitoring system.
  2. Firewall – Ensure that your internal office network is protected against external hackers by installing a business class router firewall, rather than accepting the home products shipped free by your broadband supplier. Also ensure that the router is kept up to date and the firewall rules are checked and you remove those that are no longer needed.
  3. Users – Your last line of defence. Ensure that your users understand what antivirus product they use so they don’t fall victim fake antivirus adverts and ensure they are trained against email phishing attacks and social engineering.
  4. Email Filtering – The main threat of viruses is now entry via an email. This can be an infected attachment, a link on the email sending the recipient to a website with the malicious payload or a form which is designed to mimic a popular login page such as PayPal, eBay, Amazon or Office 365 but actually harvests credentials and sends them on to the attacker. Have emails directed first to a filtering company that will not only increase productivity by reducing spam, but it will greatly reduce the likelihood of infection by emails.
  5. Server Backups – Your server may hold years of valuable data. Client lists, accounts, previous orders, Word documents and Excel spreadsheets etc. If you should have a fire, a burglary, hardware failure or a computer is infected by an encryption virus, you could lose all that work in minutes. It is vital that you have two backup copies of your data in addition to your live version. One should be a full system backup onsite on an external hard-disk or NAS, and one should be offsite.
  6. PC Backups – Ensure you have configured backups for each computer to avoid data loss should they get an encryption virus or hardware failure. Alternatively, ensure your staff save all files to your server or even better on their OneDrive Accounts. They each get 1Tb of cloud storage with Office 365 Essentials or Premium.
  7. Cloud Backups – So you are saving all your key documents to Office 365 so it is safe and sound? Not quite! Microsoft do not guarantee their backups and recovery from an encryption virus is a painful process without additional recovery options. Subscribe to an Office 365 backup system now to avoid future grey hairs later.
  8. Windows Updates – Each month Microsoft release security updates to patch vulnerabilities found in Windows and Office. Without ensuring these are patched every month, you leave yourself open to hackers and viruses. Firewalls and antivirus software will help to plug these vulnerabilities but patching the operating system is a crucial layer in your security.
  9. Third Party App Updates – As well as Windows and Office security patches, all the other software that is installed on your computer is subject to new versions being released as security holes are found in programs such as Internet Explorer, Edge, Chrome, Adobe Flash, Adobe Reader, iTunes and Java. Keep these programs up to date to help your system running smoothly.
  10. Support – Ensure you know who to call when something goes wrong, or you are considering making changes to your infrastructure so you don’t open new vulnerabilities without realising it.
