Security settings on NGFW to block dangerous user agent

L0 Member

Hi All,

 

Good morning!

 

I would like to get guidance from you regarding how to block user agents on Paloalto NGFW. I mean, when I am managing Web Application Firewalls (WAF) from other provider. I am able to configure a section within the security section in the WAF, where I can block bad bots, and any other bad user agent (e.g. python, Go lang, Java, etc) used by not authorised external users to scan the website for vulnerabilities, etc.

 

Is there a way to setting up a similar security measure within Paloalto NGFW? If it is so. Could you help providing guidance for this security setting for me please?

 

Thanks in advance.

Elias

@E.SilvaHueck,

You could setup a custom vulnerability signature and set it up so it's blocked across your network. As an example, blocking GPTBot you could do the following assuming that you're decrypting inbound traffic.

                                <pattern-match>
                                  <pattern>User-Agent:.+GPTBot/</pattern>
                                  <context>http-req-headers</context>
                                  <negate>no</negate>
                                </pattern-match>
