Editing Denial-of-service attack (section)

===IPS based prevention===
[[Intrusion prevention system]]s (IPS) are effective if the attacks have signatures associated with them. However, the trend among attacks is to have legitimate content but bad intent. Intrusion-prevention systems that work on content recognition cannot block behavior-based DoS attacks.<ref name=":0" /> An [[Application-specific integrated circuit|ASIC]] based IPS may detect and block denial-of-service attacks because they have the [[Bandwidth (computing)|processing power]] and the granularity to analyze the attacks and act like a [[circuit breaker]] in an automated way.<ref name=":0" />
