One of our faced some attacks from their wan interface IP. The issue is reported by their ISP team, when we checked in the firewall there are no logs.
In customer network, huge number of traffic is going at the same time. The device is 3020. Already customer is facing some slowness in the network traffic.
Kindly share the Remedies for block ransomware attacks.
Do you have Zone Protection enabled? While you are asking about ransomware, the fact that your ISP is reporting an issue means you are more than likely actually experiencing a DoS/DDoS attempt. ISPs generally speaking would not be monitoring for any other sort of threat, as it really has no basis on their operations.
The firewall by default doesn't log intrazone-default traffic, which would be how traffic received by your untrust interface would actually get logged. You may want to override that so that it logs at session-end so that you record those logs. I'd recommend reading up on zone protection and spending some time getting it properly configured so that you are at the very least alerted of the issue before your ISP is contacting you.
