Hi, i want to create an app signature for our Forcepoint Web Proxy and i have been trying to create the signature but I get the same error:

 

F-SBID( --name "Forcepoint-Forcepoint.Cloud"; --pattern "webdefence.global.blackspider.com)"; --service HTTP; --service HTTPS --protocol tcp; --protocol udp;)

As an example:

edit "OpenSSL.TLS.Heartbeat.Information.Disclosure-custom.All.20443"
set action block
set comment 'SSL on port 20443'
set signature "F-SBID( --attack_id 4983 \
--name \"OpenSSL.TLS.Heartbeat.Information.Disclosure-custom.All\"; \
--protocol tcp; --src_port 20443; --flow from_server,reversed; \
--pattern \"|18 03|\"; --context packet; --within 2,context; \
--byte_test 2,>,100,1,relative; )"
next

Which error?

Is the closing paranthesis in the pattern by design or an oversight?

It is an oversight, this is the correct one

 

F-SBID( --name "Forcepoint-Forcepoint.Cloud"; --pattern "webdefence.global.blackspider.com"; --service HTTP; --service HTTPS; --protocol tcp; --protocol udp; )

 

The error i get is: "Failed to save changes"

So you've got a syntax error.
