In a Nutshell – Deep packet inspection (DPI) looks at the contents of data packets, rather than just their headers, leading to more effective security for your network devices.

With the increasing cybercrimes and web attacks prove that the existing web security is under threat in a continuous manner. Year 2018 Witnessed 21% jump in total Virus Attacks worldwide. Hackers are more and more hungry to sneak into your web security and destroy that web application you worked so hard on or share the data with your immediate competitors.

Moreover, with each passing day web attacks are getting smarter, and fighting them is a bottom-line requirement for your online business in order to stay afloat on the web. So, what does your web security standard desperately need? Continuous evolution backed by the research and analysis of recent web attacks.

Deep packet inspection (DPI) is one of the strongest players in the web security niche and it has the potential to outsmart modern web attacks. DPI is an integration of security functions, user service and network management, and these parameters are the building blocks of modern web security protocols. Furthermore, there is a high demand for a versatile web security layer in every sector of the web like big enterprises, global telecom services and governments.

The internet of things (IoT) is becoming a necessary evil for the modern world, as it is fostering new ways to build web attacks, and DPI is one of the best weapons we have for combating these threats. Remember “Every Connected Device poses a threat to the integrated Network”. So its like “Once its inside your network, Its inside already ! “

What Is Deep Packet Inspection?

Deep inspection is a process of network packet filtering. In this method, the data part of a packet is examined at an inspection point for the detection of any unwanted activity, such as spam, viruses, intrusions, or to define a network’s criteria to maintain its flow to the proper destination.

The system is also capable of extracting statistical data from the Open Systems Interconnection (OSI) model application layer.

Now, this is the place where DPI plays an important role. In the entire network of worldwide data flow, almost all of the information passes through unmonitored. In this case, DPI implementation involves uncovering the identity of the packet information. It doesn’t simply check a packet’s header and footer, but scans the data content in each packet. Only after meeting some special criteria of a highly selective firewall, the packet gets re-routed to a particular path which best suits it, depending on the bandwidth measurement.

Undeniably, DPI is the most efficient way of straining out every possible threat over the entire data network by disassembling and examining the payload, reassembling it, and then determining whether to reject it or to transmit it in the most suitable traffic. Not only that, DPI engines strengthen the security protocol by implementing stealth payload detection, signature matching and other similar activities.

So the Conclusion :

Data security is the goal of the day for any business, and only deep packet inspection can ensure this.

DPI is a good reason for celebration for web users. DPI is a shield for us, as it adds an enhanced level of data security to our existing web security system. The cyber world has experienced the blow of heinous attacks like DDoS, ransomware and others.
