Hi Shang ,

Follow bellow the answers about your questions

- Are any of you experience the same issues?

A - In a first installation of any IDS/IPS system in a new environment
at the beginning its possible to have some problems like
false-positive alerts but nothing traumatic , but you really needs
perform a fine tunning.You need a period on the IPS/IDS only in the
monitoring mode ( reporting without actions ) in your network and
after this you can analyze the reports and check if the alert is
really an atack or a simple false-positive , and you can add a
exception for this when you put the IPS/IDS in prevent mode (reporting
with actions - drop , accept ...etc).

- Is these disruptions common to others or should we seriously
consider replacing the IDS and/or the outsourcing company?

A - This is not common when you have a correct implementation of the IPS/IDS.
I thing you jumped the step of the fine tuning / monitoring time in
your IPS implementation and you really need to do this.If possible
contract a consultant company (prefer business partner of IBM/ISS) to
check and audit the actual configuration after this you can measure if
you really need to replace the outsourcing company.In my opinion the
IPS/IDS of the ISS company is one of the best systems at world.

- Could this be an issue with our network infrastructure?

A - Maybe , without any information its complicated to say "is
network problem or IPS/IDS configuration problem or a network
architecture problem"

PS: I answer your questions considering you have a product compliance
with the manufacturer life cycle time , and using the last updates.
If is not this my answer can change!

I hope you appreciate my help.

Regards ,

Antonio
