  • DHCP client lease time based threat detection for authorised users
    Patent number: 10187354
    Abstract: Methods and systems are provided for determining a leased time for an address leased for a first user device. The determined leased time and leased address may be stored in a first database. Upon receiving a renew/rebind request from the first user device, a request counter in the first database may be increased if the renew/rebind request occurs during the leased time. A MAC address and port number associated with the address may be identified as performing unwanted actions if the request counter crosses a first threshold. After the request counter crosses the threshold a first remedial action may be taken on the first user device associated with the MAC address and port number identified as performing unwanted actions.
