How do you prevent virus infection from a network?

To prevent virus infections from a network, implement a robust firewall to monitor and control incoming and outgoing traffic. Regularly update antivirus software and operating systems to protect against the latest threats. Employ network segmentation to limit the spread of malware and educate users on safe browsing practices and the importance of not opening suspicious emails or attachments. Additionally, consider using intrusion detection systems to identify and respond to potential threats in real-time.
