DoS Protection - Calls to aspx

L2 Linker


I am wanting to create a DoS protection rule specific to http uri requests that have /*.aspx (so, the uri is at the root). I was approaching this by creating a custom application with a signature with the following:

pattern match

context: http-req-uri-path

pattern: /*.aspx/*

qualifier: http-method GET

However, this pattern does not meet the 7byte limit.

Is there another/better way to go about this?

Thanks in advance.

Hello Amy,

Could you please go through the below mentioned documents and try to find an another match which contains at least 7 Byte strings.

Custom Application Signatures


Thanks, Hulk.  I'm wanting to match on any URI string ending with .aspx

My challenge is that can be any number of patterns, which is why I wanted to wildcard the leading string.

Is there any easier way to match on aspx (.NET pages)?

I have worked out the correct regex for pattern matching, however now I am wanting to somehow limit packets per second for any call to aspx web pages. There doesn't appear to be a way to call a custom app in the DoS Protection profile or policy.

Is it possible to limit packets per second to a specific HTTP page request?
