In the packet transfer during communication through a network, it is important to check the traffic. A packet while moving through a channel can face various hurdles. Thus it is important to monitor the entire network to check the availability of the network and check if there is some operational and security issue.
It is important to transfer data to the right destination in the computer network without loss and with a proper format. This process is known as Deep Packet Inspection or DPI.
What Are The Advantages of Performing Deep Packet Inspection?
Transferring data safely and securely to its destination needs high monitoring in a network channel. DPI helps in good network management, keeps check on security functions, and helps in data mining. The primary usage of DPI is at an enterprise level, different telecommunications services, and used by the government in several applications.
Several IT administrators and security officials prepare different policies and use them in different network layers. Thus it prevents certain attacks that might occur while packet transferring and hence prevents data leakage. Thus DPI is important in securing your data while it is transferred over a large network in packets.
What Are The Use Cases Of DPI?
DPI is like a complete package for intrusion detection and prevention. Usually, a firewall and normal intrusion prevention cannot adequately detect threats to the data, but a DPI can do this.
Suppose you have been working in any organization, say a telecommunication services provider company. Thus a company needs to prevent data loss, viruses, spyware, and worms not to affect crucial information. DPI helps in preventing this data and allows network detection and only permits defined applications to work.
Also, there is an ease for the flow of important information on high-priority using DPI. Suppose, you are to send important information in a network, that message is passed to the destination with a high-priority. DPI is used in applications that help many Internet Services Providers to save their IoT devices from exploitation and saves it from unwanted attacks.
What Are The Different Options Available In Deep Packet Inspection Applications?
There are different options available in DPI applications. Some of them are listed below:
Quality of Services
Quality of Services is important in the case of bandwidth management. It is to check data usage and data flow through a network. DPI helps in sending high-priority messages first and thus improves the quality of services.
CG-NAT
In a network, it is important to have smooth network addressing and port translation. Carrier-grade NAT approach is used for mitigating IPv4 address exhaustion. It is useful in sending data through a specified port. CG-NAT is to address the issue of threat when data is passed over a public network.
Quality of Experience
In a network, DPI works to gather statistics. Thus the final output data is compared with preset metrics. It works to gather the quality of experience that a single user faces in telecom services and the kind of internet connection. Thus DPI also helps in improving the quality of services for packet transfer.
Firewall and Anti-DDoS
While data transfer, a network usually faces data hacking and other illegal subscribers are introduced. It is important to transfer data to the destination safely. Applications like Stingray SG use a DPI that comes with a special type of firewall that prevents malware attacks. Along with the QoE module and this firewall, you can easily detect various malfunctioning and quickly notify you about it.
