Monitoring sql server login attempts including IP ?! please help

Hello
I am using sql server 7 and I am doing a trace on successfull sql logins and
also on unsuccessfull ones.
Everything works fine, but the only thing missing for my trace to be
accepted is the origin IP address ?
I have to have the trace to have the IP adresse from where the sql login is
attempted from.
I know that from the process info I have the Host wich is actually fine, so
I imagine that the trace could include it or I could have a query to lookup
some other systable....
I really have to have this report....
Thanks !Trace (profiler) does not include the IP , and i don't know how to get it
( other than going through the hostname)

I actually can't even have the hostname from the trace, I get it from the
process info.
is there any way of cross querying the trace with the process info ? huhhh
now that I think of it, it will be pretty hard sine the failed login will
not show up on the process info.
thanks !

don't track the IP address for failed login attempts. I've requested this
feature for Yukon.
The only way you could capture this is to run a network trace on the server
while it's happening.

Monitoring Invalid Logins

I have a feeling someone is running a brute force password program against my
SQL Server. How can i see how many invalid attempts there was? And from which
IP Address? sp_monitor does not give me much information.
Thank you!
You can try a network sniffing utility like Network Monitor.

|||You can log failed logon attempts to the SQL Server log. Right-click the
server in Enterprise Manager and choose properties. Go to the security tab
and check the appropriate option under Audit level. Failure is I think the
default anyway. You can check the SQL Server logs, under the management
folder for the results.
From there you can see how many attempts there were, and against which
account, but that's about all the information you get. If you want more
information, you can set up a SQL Profiler trace, using the Audit Login
Failed Event.

Monitor service account logins

Hello,
I've been asked to create a method of alerting if the account that the
MSSQLSERVER service runs under is used to attempt to log into the
database from another workstation. Here's what I've thought of so far:
OPTION 1: Monitoring for all login attempts. I don't want to do this as
we get about 200,000 logins an hour ( a seperate issue).
OPTION 2: I could do it via a server side trace but I'm not sure how I
could get an alert out of this without reading the trace file every
couple of minutes.
OPTION 3: I could run a query every minute that queries the
sysprocesses table but this leaves the possibility of sessions that
last under a minute not being picked up.
Can anyone think of a more elegant way of doing this? I'm leaning
towards option 2.
Cheers
DaveHello lightning-dave,

If you are running SQL 2005, you might want to give this [0] a read and
see
if it useful in this case. Instead of having the event write to an output
table, you could have send an email, alert, whatever.

How do I monitor who is adding or removing logins from sql server roles?

Try this , I found this in my collection , but I don't remember who wrote
the script
select identity(int,1,1) as traceid, a.name as [Database],

ltrim(rtrim(b.loginame)) as loginame,ltrim(rtrim(b.program_name))
as program_name,ltrim(rtrim(b.hostname))
as hostname into #audittrace from master.dbo.sysprocesses b (nolock) ,
master.dbo.sysdatabases A where
a.dbid = b.dbid and ltrim(rtrim(loginame)) not in
('DBA1','domain\systemaccount','DBA2','d
omain\administrator') and
ltrim(rtrim(left(program_name,8))) in ('MS SQLEM','SQL Query Analyzer')
--drop table #audittrace
select * from #audittrace
declare @.count int
declare @.message varchar(1000)
set @.count = (select count(*) from #audittrace)
While @.count >=1
begin
set @.message = (select 'SQL Security Enhanced Auditing: SPID =' + spid +'

like a service. I've created a template that I'd like to use when SQL server
starts up. I'm doing plenty of reading (SQL Bookis Online) but I'm not get
that far after creating the template and running via Profiler. Or if you or
others could point me to some good documentation/examples.

I can't even get the sp_trace_create script to work. Have you used the
script before? or could you maybe do a quick test to see if the script works
for you?
