Sniffing countermeasures protect networks from unauthorized packet capture and data interception. To defend against sniffing attacks:
Use Encryption – Implement SSL/TLS, IPsec, or VPNs to secure data in transit.
Switch to Secure Protocols – Replace FTP, Telnet, and HTTP with SFTP, SSH, and HTTPS.
Segment Networks – Use VLANs and firewalls to isolate sensitive traffic.
Monitor Traffic – Employ intrusion detection systems (IDS) and anomaly detection tools.
Secure Physical Access – Prevent unauthorized access to network hardware
