Source IP:    Spain

From Zone: Untrust

to my web server:

Destination IP:    195.77.XX.XX

Destination Port:    80

To Zone: DMZ

Multiple Vulnerabilities Types Targeting a Single Source

Acunetix Web Vulnerability Scanner Detection

Microsoft IIS Escaped Characters Decoding Command Execution Vulnerability

How can I avoid or prevent this type of vulnerability scanning? or what recommendations do you suggest me?

Thank you.

First you can activate on the security rule the DSRI which will prevent analyse on your server answer.

Or you can create a custom profile for this rule

At the end on your global profile you can disable some alert.

Hope help

Here is a doc that explains on how to exempt an ip address from threat profile

How To Add Exempt IP Addresses From the Threat Monitor Logs

You can use the above doc so it will not scan that.

Here is another useful doc regarding threat prevention.
