However, due mainly to the diverse logic used in web applications, the inherent variety of vulnerabilities presents a rather large attack surface, which often cause IPSs to produce a large number of false positives. Here you can configure it to dynamically react and block traffic it detects as being potentially harmful.

Unlike an IDS, which passively observes traffic, an IPS typically sits inline, with traffic passing through it before being forwarded on to its destination. Differences between IDS, IPS and WAFĪn Intrusion Detection System (IDS), like an Intrusion Prevention System (IPS), sits within your network examining packets for anomalous behavior.

One of the most effective is a Web Application Firewall (WAF). There are various approaches to minimize the effects of or provide alerts to such exploits. Symptoms may include a reduction in availability, a spike in resource usage or breaches in host or user security. Prevalent attacks today include denial-of-service, cross-site scripting and SQL injection. All web applications are subject to various vulnerabilities that may be exploited by hackers.
