I have installed Snort 184.108.40.206 and it does not detect majority of attacks, such as nmap port scans, downloading exe files, opening documents containing keyword "root".
I use Snort together with Pulled Pork and Barnyard2. Everything seems to function and I can see alerts on the website that is powered by BASE.
The problem is that I can only trigger 3 different alerts. Everything else is simply not detected. I want obviously to be able to get alerts when someone performs port scanning, trying to attempt to perform DDOS attack and so on. This I cannot trigger. Do I have to enable something somewhere?...
I have made my own local.rules file, which contains a single rule - monitoring of ICMP echo packets.
Pulled Pork does show that it has downloaded over 20000 rules and over 5000 rules are enabled. This can be seen in snort.rules file, which I included in snort.conf file.
The 3 alerts I am able to trigger are:
- stream5: TCP Small Segment Threshold Exceeded (this is due to my old Win SCP client)
- ssh: Protocol mismatch (this is due to my old Putty client)
- ICMP test (my own rule from local.rules)
My snort.conf can be found on the following website (had to move it there, because i reached max chars list): https://paste.ee/p/RTUgY
My pulledpork.conf can be found on the following website: https://paste.ee/p/ixZqW
My local.rules looks like this (which does work):
alert icmp any any -> $HOME_NET any (msg:"ICMP test"; sid:10000001; rev:001;)
