IDS9000

[Michael O'brien_1]

Hi,

I was thinking of implementing IDS on serveral HP servers. I was planning on using a HP workstation as the management server. Is this a good idea? If a workstation is capable of being the IDS management server, can anyone recommend a suitable model.

Thanks
Mike

Mike,

According to my experience a WS should be ok.I you need to keep the logs care for a big HD.

I use a small A-Class as mangement station; I prefer servers for tasks running 24*7*365

Hi Mike,

I have been testing this on a D & K class (as management servers). While there doesn't appear to be any problems, depending on how it is configured (the templates) and how many messages that are generated, will set a requirement for possibly a bit of disk space. Also note that depending on which options being used, there can be and I/O overhead (especially on the agent systems) - from my experience, anyway.

Regards,

Joanne

Rainer/Joanne,

Thanks for the replys, I think I will be using an A-Class, I am interested in the overhead Joanne mention on the agents as this would be a major concern if it impacts the service. We have just upgraded the application and are starting to get some decent performance from our servers. If I was to implement IDS and performance took a big hit, I don't think I would be too popular.

Thanks
Mike

Mike,

check out my top output to figure out what IDS will mean to perfomance on your system.

You'll find all ids processes among the top 10.

BUT: performance depends very heavily on what you monitor, so carefully design your schedules bases on the temlates

And last but not least: IDS is a great tool if you are really concerned about security.
