Ensure Network Optimization By Using Packet Capture Techniques
Packet capturing techniques are used for capturing and recording the data that is moving across a particular computer network. The captured data is saved for offline analysis so that you can do a survey and conduct a thorough research to determine the origin of the deterioration in end-user service and any anomalies in the network traffic. Unusual movement in traffic can be a symptom of a lapse in security. To resolve this problem, you can use Packet Capture techniques to diagnose and resolve network problems and also determine whether network security guidelines are being appropriately followed. This tool is also used by hackers to steal data that is being transmitted over networks. To avoid this, you should use appliances with inbuilt security features.
Various packet capturing techniques
Your data is never safe on public networks if you don’t take some sort of precautionary measures. Therefore, network managers and administrators who analyze and manage the overall network traffic use different Packet Capture techniques to examine and capture the data moving over a network. The most common type of technique used in this process is filtering, in which you can use filters for the network nodes or devices at the point where data is captured. The other method is used for obtaining complete packets instead of some filtered portions. The full packet contains a payload consisting of the actual contents and a header that consists of the packet’s source and destination.
Provide security and troubleshoot
One of the most significant uses of Packet Capture is to provide security by identifying security faults and lapses and for determining any critical data leakage. The system administrators utilize packet sniffing for troubleshooting issues in the network or for detecting data attacks or intrusions. Therefore, packet sniffers which were originally used as network tools are now being used as security tools which can effectively identify and monitor the movement of malicious data over a network. For this, the network manager should have complete access to a network resource so that he can troubleshoot any problem and resolve them efficiently
Maintain efficient data transmission
Packet Capture techniques are also used by the network administrator when any type of computer viruses or other threats or intrusions are identified so that the exact nature and the extent of the problem can be determined and necessary countermeasures can be taken to tackle the problem. He has the authority to block some segments of network traffic to protect all the critical and vital information and the important network data. Moreover, when data is stolen, the lost information can be fully retrieved through packet capturing techniques.
Network monitor and analyzer
Ethically, a packet sniffer should only capture the packets that were intended for the machine or network on which he has legal access. It is also referred to as a network analyzer and can be legally used by a network manager to monitor and resolve any kind of problem pertaining to network traffic. The most important reason for capturing packets is to identify and comprehend any issue related to your network connectivity, especially when you have repetitive problems with your network performance. Since packet capturing can obtain the complete data that flows across a network and gathers potentially critical and secret information, it is imperative to join a secure Wi-Fi network. But we must remember that packet capturing of network data should mainly be used for positive causes like network optimization. To read more Click Here
