ok, this is really weird,

 

We got the message "unusual traffic detected" on google when we doing google search.

 

I did some analysis and the culprit is...the Era appliance server.

 

Some module is doing this and I don't know why.

 

Where can I found the log for this issue on the Era appliance?

When you temporarily disable HTTP proxy (e.g. port 3128 is not accessible or you completely stop the service) does it help? I suspect that something is connecting through HTTP proxy on the appliance and that is causing this bursts. HTTPS communication is not cached so it goes always through proxy.

Hi Michalp!

 

I'm happy because I found the root of the problem

 

Someone is trying to use the proxy.

 

Now...How can I denied all HTTP proxy request without password?

That is not a smart move from you. Letting the http proxy without password on the ESET Appliance!!

 

I create a user password with this cmd

 

on /opt/apache/bin

 

./htpasswd -c /opt/apache/.htpasswd USERNAME

 

I create a .group on /opt/apache/ with usergroup : USERNAME on it

 

 

Added the following string on the config file on /opt/apache/conf/httpd.conf (just before </Proxy>)

 

  AuthType Basic
    AuthName "Password Required"
    AuthUserFile "/opt/apache/.htpasswd"
    AuthGroupFile "/opt/apache/.group"
    Require group usergroup

 

 

And voilà! My access file log is clean like water and I can see a the bad guys on the error log.

 

You should create a kb with this informaiton..
