Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
FastNetMon
- Versatile open source toolkit to detect volumetric DDoS attacks
-
A DDoS attack with unknown scr and dst port.
If you have a BGP peering with you ISP/upstream provider, ask them if they have a blackhole community you can broadcast to. Usually they are ASN:666. The only downside is you would only be able to advertise your IP address to that, essentially killing your internet (if that's your only IP) as long as the block is up. We usually set our filter to 15 minutes and most attackers give up after that. At this level, you probably would have your own ASN with a small range and could potentially use something like FastNetMon (https://fastnetmon.com) to automatically advertise and remove IPs from the community.

Processing netwflow data
Have you looked at fastnetmon ? It's freemium and It looks like the commercial version would work you, but I think the community edition is aslo worth a look. It's primary function is to detect DDOS attacks, but it can export data in ways that might be useful to you.

WAN Attacks is it just whack-a-mole?
To mitigate DoS attacks means you need information - preferably before the users start screaming. Running sampling on your edge router with something like Fastnetmon will give you alerting of a probable DDoS attack before it becomes a significant problem.

Into my 6th year of this ... hobby?
As a matter of fact, I played with the now deprecated Elastiflow, however I couldn't get my head around managing ELK, scrapped it pretty quickly, and Netflow did not reach the meaningful stage at that time. OpenNMS looks pretty massive that I can't run it at the moment. Thanks for suggestion though.

Threat detection
One thing I ran for a while was security onion and utilized port mirroring to mirror the uplink port from my primary switch to my LAN on my router, so I was catching anything coming into/out of my network destined for internet. I've also used ElastiFlow ( https://github.com/robcowart/elastiflow ) which is absolutely phenomenal and awesome, I did the same and it provides some great data. You could also leverage IntelOwl ( https://github.com/intelowlproject/IntelOwl ) , one thing I have added to all my VMs is a OSSEC agent, Wazuh to be specific which is free ( https://github.com/wazuh/wazuh ) and while I am not using it to its full potential such as monitoring file deletions/modifications etc it is a powerful tool.

Monitoring all inter-VLAN traffic on 9410 switch?
I'd recommend taking a look at Elastiflow (link is to the legacy version, I haven't used the pay structured tier version that replaced it) as a flow collector. Do it in a docker container, dump netflow to it, and use a sample rate that doesn't fill your collector box with flow packets after a single day. Depends on your traffic rates. We use 1 out of 250 for our rate.
