Toggle navigation Menu. Deep packet inspection offers immediate insight into network slowdowns. See More. Resolve end-user slowdowns. Resolve end-user slowdowns When users report slowness, admins first need to identify whether the cause is the network or a specific application. Analyze over 1, applications.
Classify network traffic. Classify network traffic The packet analyzer can automatically classify network traffic according to category and identify the associated risk level.
The scanner can categorize traffic based on destination server IP addresses, ports used, and measurement of the total and relative volumes of traffic for each type. With deep packet inspection, you can identify excess levels of non-business traffic that may need to be filtered or eliminated.
You can also identify traffic flowing over a network link or traffic to specific servers or applications, enabling informed capacity management. Improve quality of experience. Improve quality of experience Network Performance Monitor offers deep packet inspection of critical application performance factors within its unique Quality of Experience QoE dashboard.
Configure DPI alerts. These traffic packets are then scanned through the nDPI protocol to detect packet flows. But DIP is a high resource consumption technology, so it is reserved for large enterprises, ISPs, and even governments.
It has always been state-of-the-art network management and now it is used in different scenarios other than security and routing. It is helping companies with Internet data mining, block traffic to competition, eavesdropping, and even Internet censorship. If you have a powerful server or want to test the DPI functionality on a small scale, download one of the tools shown above and give them a try!
Looking at just one portion of the packet makes routing much more efficient and fast. But in the post-mailing system, a mail carrier cannot open the package to inspect its contents. In the networking space, a router can do a lot more than just checking the destination address.
As mentioned before, a router would typically only look at the IP header of a packet. In the same case, to route based on the transport layer, the L4 switch was born. DPI technology takes a step forward. In other words, the DPI technology can look into: Layer 2 frames. Layer 3 IP headers. Data protocol structures But most importantly, the Payload of the message The payload is the actual data that is not supposed to be discarded or opened until it reaches the final destination.
The problem here is that the results are too verbose. But not every router or firewall can handle deep packet inspection. Identify some attack signatures and patterns. Firewalls with features like content inspection and Intrusion Detection Systems aim to protect the network using deep packet inspection. The key techniques used for deep packet inspection include:. Pattern identification or signature matching: Firewalls with adopted IDS features can use pattern identification and signature matching techniques to detect threats from a known database by analyzing each packet.
Protocol anomaly: Firewalls with IDS features can use a protocol anomaly approach that works on the key security principle. It uses a default-deny approach and protocol definitions to determine which content can pass. This approach is different from signature matching as it offers protection against unknown anomalies or threats. IPS solutions: An intrusion prevention system is a network security protocol that detects and prevents identified or known threats.
Organizations must use deep packet inspection software to ensure their system uses minimal bandwidth with low overhead on nodes. DPI software helps you view high-level metrics, configure security metrics, deploy sensors, and more. Additionally, deep packet analysis also helps you: Measure business-critical applications with high network latency Improve application availability and meet SLAs Generate reports on historic data and perform forensics It can be used for different purposes such as: Blocking malware: DPI helps block threats and malware before it disrupts network assets.
The key techniques used for deep packet inspection include: Pattern identification or signature matching: Firewalls with adopted IDS features can use pattern identification and signature matching techniques to detect threats from a known database by analyzing each packet. With about 7 billion internet-connected devices according to data from IoT Analytics next-generation SIEMs need to tackle the latest security breaches with advanced analytics.
The challenge is in managing SIEM solutions to eliminate false positives and sort through the massive amount of data they supply quickly and efficiently. In the times of 5G, industry 4. DPI-based solutions help vendors obtain the scale necessary to accommodate growing numbers of subscribers and large amounts of traffic or connections.
At the same time, they contribute to controlling costs and improve the quality of experience QoE for their customers. DPI plays a vital role for vEPC and 5G core vendors when it comes to adding value to their solutions and asserting their market position successfully. The DPI software allows WAP providers to monetize Wi-Fi networks via enhanced real-time monitoring capabilities that enforce QoS based on dynamic network conditions to prevent Wi-Fi congestion, enforce usage rules for personal devices once they are on the network and strengthen network security measures.
In the era of cloud applications, network firewalls have to be more than just security devices. They must also ensure users have uninterrupted network availability and robust access to cloud-hosted applications. Deep packet inspection DPI is the key technology they need to become the crucial factor in ensuring availability and security on distributed networks.
