To protect against packet sniffing, several measures can be implemented:
1. Encryption: Use end-to-end encryption for email communications. Protocols like SSL/TLS ensure that data is encrypted during transmission, making it difficult for sniffers to extract useful information. 2. VPNs: Utilize Virtual Private Networks (VPNs) to create secure connections over the internet, thereby reducing the risk of packet interception. 3. Secure Email Services: Use secure email service providers that offer built-in encryption and other security features. 4. Network Security: Implement strong network security practices, such as firewalls, intrusion detection systems, and regular monitoring for unusual activity.
