Snort3 Install
Snort is an open source network intrusion detection system capable of performing real-time traffic analysis and packet logging on IP networks.
It can perform "protocol analysis," "content search," and "matching," and can be used to detect a variety of attacks, including "buffer overflows," "stealth port scans," "CGI attacks," "SMB probes," "OS fingerprinting attempts," "semantic URL attacks," and "server message block probes.

6. Create custom local rules
|
1 2 3 |
# vi /usr/local/etc/rules/local.rules alert icmp any any -> $HOME_NET any (msg:"ICMP connection test"; sid:1000001; rev:1;) |
7. Verification of settings
Use parameter -T to test configuration and enable test mode
|
1 |
# snort -T -c /usr/local/etc/snort/snort.lua -R /usr/local/etc/rules/local.rules --daq-dir /usr/local/lib/daq -i ens160 -l /var/log/snort |
Next, run the test by executing the following command
|
1 |
# snort -c /usr/local/etc/snort/snort.lua -R /usr/local/etc/rules/local.rules --daq-dir /usr/local/lib/daq -i ens160 -l /var/log/snort -A alert_fast -s 65535 -k none |
When pinging this server from another PC in the same local network, an alert line is written on the console screen of this server as shown below.
