Cisco Business Switches support a wide range of security capabilities to safeguard the information asset of small businesses. Secure Sockets Layer (SSL) encryption protects management data. IEEE 802.1X port security tightly limits access to specific segments of your network. IP-MAC port binding (IPMB) prevents spoofing and detects and blocks deliberate network attacks. IPv6 First Hop Security extends the advanced threat protection to IPv6. Secure Core Technology (SCT) ensures that the switch is able to process management traffic in the face of a Denial-of-Service (DoS) attack.
