An intrusion prevention system (IPS) monitors network traffic for malicious or unwanted behavior and can block, reject, or redirect that traffic in real time Sound familiar It should: While many vendors will argue that an IPS is a different animal from an IDS, the truth is that most IPS are merely expansions of existing IDS capabilities As a core function, an IPS must be able to monitor for and detect potentially malicious network traffic, which is essentially the same function as an IDS However, an IPS does not stop at merely monitoring traffic it must be able to block, reject, or redirect that traffic in real time to be considered a true IPS It must be able to stop or prevent malicious traffic from having an impact To qualify as an IDS a system just needs to see and classify the traffic as malicious To qualify as an IPS, the system must be able to do something about that traffic In reality, most products that are called IDSs, including the first commercially available IDS, NetRanger, can interact with and stop malicious traffic, so the distinction between the two is often blurred The term intrusion prevention system was originally coined by Andew Plato in marketing literature developed for NetworkICE, a company that was purchased by ISS and which is now part of IBM Like IDSs, most IPSs have an internal signature base to compare network traffic against known bad traffic patterns IPSs can perform content-based inspections, looking inside network packets for unique packets, data values, or patterns that match known malicious patterns Some IPSs can perform protocol inspection, in which the IPS decodes traffic and analyzes it as it would appear to the server receiving it For

example, many IPSs can do HTTP protocol inspection, so they can examine incoming and outgoing HTTP traffic and process it as an HTTP server would The advantage here is that the IPS can detect and defeat popular evasion techniques such as encoding URLs as the IPS sees the traffic in the same way the web server would when it receives and decodes it The IPS can also detect activity that is abnormal or potentially malicious for that protocol, such as passing an extremely large value (over 10,000 characters) to a login field on a web page Unlike a traditional IDS, an IPS must sit in line to be able to interact effectively with the network traffic Most IPSs can operate in stealth mode and do not require an IP address for the connections they are monitoring When an IPS detects malicious traffic, it can drop the offending packets, reset incoming or established connections, generate alerts, quarantine traffic to/from specific IP addresses, or even block traffic from offending IP addresses on a temporary or permanent basis As they are sitting in line, most IPSs can also offer rate-based monitoring to detect and mitigate denial-of-service attacks With rate-based monitoring, the IPS can watch the amount of traffic traversing the network If the IPS sees too much traffic coming into or going out from a specific system or set of systems, the IPS can intervene and throttle down the traffic to a lower and more acceptable level Many IPSs perform this function by learning what are normal network traffic patterns with regard to number of connections per second, amount of packets per connection, packets coming from or going to specific ports, and so on, and comparing current traffic rates for network traffic (TCP, UDP, ARP, ICMP, and so on) to those established norms When a traffic pattern reaches a threshold or varies dramatically from those norms, the IPS can react and intervene as needed Like a traditional IDS, the IPS has a potential weakness when dealing with encrypted traffic Traffic that is encrypted will typically pass by the IPS untouched (provided it does not trigger any non-content related alarms such as rate-based alarms) To counter this problem, some IPS vendors are including the ability to decrypt Secure Sockets Layer (SSL) sessions for further inspection To do this, some IPS solutions will store copies of any protected web servers private keys on the sensor itself When the IPS sees a session initiation request, it monitors the initial transactions between the server and the client By using the server s stored private keys, the IPS will be able to determine the session keys negotiated during the SSL session initiation With the session keys, the IPS can decrypt all future packets passed between server and client during that web session This gives the IPS the ability to perform content inspection on SSL-encrypted traffic You will often see IPS (and IDS) advertised and marketed by their wire speed or amount of traffic they can process without dropping packets or interrupting the flow of network traffic The term wire speed refers to the theoretical maximum transmission rate of a cable or other medium and is based on a number of factors, including the properties of the cable itself and the connection protocol in use (in other words, how much data can be pushed through under ideal conditions) In reality, a network will never reach its hypothetical maximum transmission rate due to errors, collisions, retransmissions, and other factors; therefore, a 1 Gbps network is not actually capable of passing an actual 1 Gbps of network traffic, even if all the components are rated to handle 1 Gbps When used in a marketing sense, wire speed is the maximum throughput rate
