content of websites, email attachments, and files for malware.
4. Keep your operating system, software and all devices updated on an ongoing basis.

email protection have been updated to the latest version.
6. Divide your network into specific security zones so that malware caught in one zone cannot spread to others.
7. Security training courses to teach employees not to download files, 
open email attachments, or follow unknown links in messages.
