This is my first post. If this looks silly plz. forgive me.
I want to know how to make sure an IPS is reliable one or not?
For ex. if we put across parallel attacks simultaneously, say DoS attacks, is that enough for me to conclude an IPS is stable & reliable. (if it doesn't buckle under pressure)!
What you need is to have a security assessment or penetration-test done for the IPS and the network it is protecting. Basically, a penetration testing team will attempt to bypass your IPS and see whether it's really doing its job.
