  • Hi John,


    Which setting in ASM policy need to be configured to inspect such traffic?


    How ASM would protect against such attack ?







  • Hi sachin...great question! The ASM handles Insecure Deserialization mostly through attack signatures. So, it should catch these attempts as a normal part of the way it functions no matter which type of policy you create. Just make sure the standard attack signatures are enabled (which they are by default on any policy). A few examples of signatures that catch Insecure Deserialization attempts are:


    • 200004188 PHP object serialization injection attempt (Parameter)
    • 200003425 Java Base64 serialized object - java/lang/Runtime (Parameter)
    • 200004282 Node.js Serialized Object Remote Code Execution (Parameter)

    Hope this helps!
