which ports needs to be open for IP based discovery for GCP VM's ?

[Shraddha Dube]

Hi,

We ran the GCP ServiceNow Discovery with enabling VM's (Ip based discovery) option beacuse there is need to run ip based discovery for GCP VM's also.

For that we enable PORT 135 , PORT 22 ,DCOM PORT Range From 49152 to 65535 and PORT 445 but still authentication getting failed and we are facing errors like Adding target to blacklist. No valid credential found for type [Windows] and for SSH also.

Please help us on this like any other ports needs to be open or not?

Thanks in advance!!

Hi,

The ports depends on the operating system but since you get credentials errors then the ports are fine. Basically the ports scan phase (Shazzam) returns an open port and triggers a login attempt which seems unsuccesful. You need to fix the credentials to be able to fulfill the discovery.
