  Make your employees aware of possible dangers from the Internet so that they do not open file attachments from unknown senders or download files from unknown Internet sites. This way you can reduce the risk of your network devices being infected by Malware (e.g. the encryption Trojan Locky).

• Encrypt data transmission
  Data transmission over the internet should be encrypted. Most routers and network devices supported appropriate encryption protocols, such as IPsec.
