[Snort-users] SNORT daily report

[Maneesh Patel]

I am running an apache2 server on Ubuntu 10.04 (with ssh also
running). I recently installed snort. I apologize for this
elementary question, but I am having trouble understanding the daily
report e-mailed by snort. There are various lines such as

COMMUNITY SIP TCP/IP message flooding directed to SIP proxy
(ftp_telnet) FTP traffic encrypted

some to my IP address, some from it. I would like to know what I
should be looking out for, which lines in the report are innocuous and
which might require some countermeasures. The snort man page does not
shed light on this, as far as I can tell. Can someone please direct
me to some documentation that clarifies the daily report?

Snort itself doesn't generate a daily report Something else must be
doing that. Is it part of the daily log job? The report that includes
drive space, etc? Could it just be repeating the alerts that snort
generates? Do you have Barnyard set to output snort alerts to syslog
so you can cross check that info?

It's called something like snort-summary and you can find it being called in the /etc/cron.d directory I think.

It just summarises /var/log/snort.alert - no particular magic.

Cheers,
Jamie

"snort-stat" is the program that generates the report:
http://docs.byteme.org.uk/man/en/snort-stat.8

However, as Ian says, you'll need to check each alert to see if it's
correct - which is a great way of learning about your network.
Ideally, try to use some interface (I use base from secureideas, but
that's a bit dated) where you can pull up the packet itself fairly
easily. Google is very much your friend here :)

cheers,
Jamie

interesting... i've never seen such in my pure/plain snort installations... i do
have something that rotates the alert file each week and the sfportscan log
monthly, though... what is used to generate that summary and where might it be
found? it may be of some interest to my/our installations ;)
