Rogue Device Detection for Network Security
NetOpsVA, a virtual appliance designed to enhance network security by detecting unauthorized devices. It primarily details two key functions: rogue_arp_detect and rogue_mac_detect. rogue_arp_detect monitors ARP tables on both Cisco and Juniper devices to identify rogue devices and misconfigurations by comparing MAC addresses against an authorized OUI list. Meanwhile, rogue_mac_detect focuses on Cisco switches, scanning MAC address tables to flag unauthorized MACs and detect duplicates on the same VLAN or port. Both functions ignore reserved MACs and leverage OUI databases to differentiate legitimate from illegitimate network entries, ultimately offering benefits such as enhanced security, centralized monitoring, operational efficiency, and support for regulatory compliance.
