ARP spoofing is a popular technique used to set up a Man-in-the-Middle attack. Which of the below can mitigate ARP spoofing from being successful?
OS Security
VLAN segregation
Increased size in the Forwarding Information Base or CAM table
Static ARP entries
ARP spoofing detection software
All of the Above
Static ARP entries - IP address-to-MAC address mappings in the local ARP cache may be statically entered so that hosts ignore all ARP reply packets.
OS Security - Operating systems react differently, e.g. Linux ignores unsolicited replies, but on the other hand users see requests from other machines to update its cache. Solaris accepts updates on entries only after a timeout. In Microsoft Windows, the behavior of the ARP cache can be configured through several registry entries under HKEYLOCALMACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters, ArpCacheLife, ArpCacheMinReferenceLife, ArpUseEtherSNAP, ArpTRSingleRoute, ArpAlwaysSourceRoute, ArpRetryCount.
ARP spoofing detection software - Software that detects ARP spoofing generally relies on some form of certification or cross-checking of ARP responses. Uncertified ARP responses are then blocked. These techniques may be integrated with the DHCP server so that both dynamic and static IP addresses are certified. Software includes "Anti-Arpspoof", "DefendARP", "ArpOn", etc.
