Deny Decline Messages Edit '/etc/dhcp/dhcpd.conf' and add or correct the following global option to prevent the DHCP server from responding the DHCPDECLINE messages, if possible: 'deny declines;'

The DHCPDECLINE message can be sent by a DHCP client to indicate that it does not consider the lease offered by the server to be valid. By issuing many DHCPDECLINE messages, a malicious client can exhaust the DHCP server's pool of IP addresses, causing the DHCP server to forget old address allocations. Fix: No Remediation Info
