I'm going to do some service availability test in the near future. We can't get any information of the attack pattern. The only information we know is that the tester will conduct these attack.
I'm afraid that those attack patterns seem to be normal for the PAN device (It's like brute force attack, working base on the threshold value)
I've heard that the best way to block these kinds of attacks is the setting server's timeout value or threshold value.
But I have to find out some way to do this job with PAN.
Can we block those attack with IPS Dos Signature or Custom Signature? If we can, does anyone know how set-up to the custom signature for those attacks?
Solved! Go to Solution.
you can found explanation for DOS protection by paloalto with this doc https://live.paloaltonetworks.com/docs/DOC-5078
but there is no information in this doc about HTTP DDOS.
I'm interresting in hhtp ddos too
I think these attacks can exhaust server resource with normal Http transaction, and before the the server reaches its max concurrent connection limits, its resource worn out ..
And PA's Dos Protection uses Layer 3~4 information, those attacks are based on Layer 7 information (Http get, post value etc...). In my opinion I should be able to set up Http get method threshold.
I've found one IPS signatures which can block HTTP Slowloris attack.. :smileygrin:
|Attack Name||HTTP: Apache Denial Of Service Attempt|
|Description||This event indicates that someone want to exhaust the apache resources, as described by slowloris.|
I think it's not exact for your case. HTTP: Apache DOS signature that triggered only 40 times in 60 second and only Apache related case. In my case I created a Custom Signature for HTTP post, CC that blocked in security rule while having BMT.
