Mitigation for DHCP Starvation attack in shared network zone (e.g.Eduroam)

L1 Bithead

Hi everyone, 

Is there anyway for us to utilize Palo NGFW to prevent or mitigate DHCP starvation attack. 

For example, a user's BYOD device is infected with malware, after authenticated with eduroam network, the device start performing DHCP starvation attack without the user even realize.  


I have tried looking online for solutions, there's recommendation such as DHCP snooping, port security in layer 2 but not sure if it is effective for shared network/wifi zone. 


Thank you in advance your help!

Hello LuckyLau,


You can set some rate limiting toward the DHCP server with DoS profile.


But not sure it is as efficient as other L2 mechanism (I'm a fan of blocking as soon as possible an unwanted traffic)
