switch security features
Switch security features represent a comprehensive suite of protective measures designed to safeguard network infrastructure and data transmission. These features incorporate multiple layers of defense, including port security, access control lists (ACLs), and VLAN segregation. Port security allows administrators to specify which devices can connect to switch ports based on MAC addresses, effectively preventing unauthorized access attempts. The implementation of VLANs enables network segmentation, creating isolated broadcast domains that enhance security by controlling traffic flow between different network segments. Advanced features include Dynamic ARP Inspection (DAI), which prevents ARP spoofing attacks by validating ARP packets, and IP Source Guard, which blocks IP spoofing attempts. Additionally, DHCP snooping provides protection against rogue DHCP servers and man-in-the-middle attacks. The switch security framework also includes Storm Control mechanisms to prevent network floods, and 802.1X authentication for port-based access control. These features work in concert to create a robust security infrastructure that protects against both internal and external threats while maintaining network performance and reliability.
