This is the third and final part our blogs about the National Cyber Security Centre (NCSC)’s tips on keeping safe from ransomware.
What is the impact of ransomware?
Ransomware prevents you from accessing your systems, your data, or both until you find a solution. If those systems are delivering business critical services, this can have a serious impact on your reputation, finances and your customers. Even if you took a recent backup of your system, it may still take some considerable time to restore it and you may even restore a backup that has formant ransomware on it. This is why we help organisations to write Business Continuity plans and install backup solutions.
Limiting the impact of a ransomware attack
The following measures will help to limit the impact of an attack by ransomware.
Access control: Don’t use the administrator account for day to day business, and never share passwords. The encryption may only apply to the data owned by a single affected user, but if you share logins then everyone is affected.
Need to know: limit the access to your data and file systems to those who have a business need to use them.
Keep backups of your data. Organisations should always have a fully tested backup solution in place. Backup files must never be directly accessible by any machines that could be infected by ransomware – or it could spread to your backups too.
What to do if your organisation is infected by ransomware
Unplug any affected machines from the network, and switch them off at the mains. Then call an expert for advice. We can help businesses prevent ransomware and we may be able to help you recover if you have been attacked.
