Installing Snort Intrusion Detection System.
Snort is an intrusion detection system that can monitor network traffic and alert on malicious traffic or just monitor what users are doing on the network, in case they breach the policy.
apt-get install snort
When snort asks for the interface, enter: br0
When snort asks for the network mask, enter: 192.168.0.0/16 (This includes the Bubba LAN network, and any additional networks you may create later for VPN, as long as they start on 192.168.*.*)
Do not select yes to disable promiscious mode.
You may enter an email address to e-mail alerts to.
When snort asks for special options, enter -X, that will save full packet dumps as well for later analysis.
Enable missing rules (In this case we enable the the porn, chat and p2p rules)
nano /etc/snort/snort.conf
Uncomment the lines below and save the file.
# Policy related rules: # include $RULE_PATH/policy.rules # include $RULE_PATH/community-policy.rules include $RULE_PATH/porn.rules # include $RULE_PATH/community-inappropriate.rules include $RULE_PATH/chat.rules # include $RULE_PATH/multimedia.rules include $RULE_PATH/p2p.rules # include $RULE_PATH/community-game.rules # include $RULE_PATH/community-misc.rules
Example: Edit the rules file:
nano /etc/snort/rules/chat.rules
Install Bleeding Edge Rules:
Restart snort
service snort restart
To start snort
service snort start
To stop snort
service snort stop
To check snort status
service snort status
Change snort parameters later:
dpkg-reconfigure snort
Check snort alerts: (For example filter all MSN traffic)
cat /var/log/snort/alert | grep -B5 MSN
