I know that Intrusion Detection System(IDS) and Intrusion Prevention System(IPS) is worthwhile for a network. However, for a personal computer, is it really worthwhile? I am using TPF 6.0 now. I just turned on the IDS/IPS feature without any configuration so far (I am not sure if it worth the time to configure it ). Also, I found that many people consider the IDS/IPS feature as a factor when they are looking for a personal firewall. My question is, is IDS/IPS really so important for a personal computer?
