What Is Wireshark and How Can You Use It to Secure Your Network?
As cyber criminals become more advanced, securing your network has become more important than ever. One of the ways that you can secure your network is by using a tool called Wireshark. Wireshark is a free and open-source packet analyzer that allows you to see the network traffic in real-time and analyze it to identify potential security vulnerabilities.
What is Wireshark?
Wireshark is a network protocol analyzer that enables you to see what’s happening on your network in real-time. It is free and open-source software designed for network troubleshooting, analysis, software and communication protocol development. It offers a wide range of features that can help you identify and isolate problems on your network.
Wireshark is designed to capture and analyze the network traffic that flows through your network. It can decode and analyze a wide range of network protocols, including TCP/IP, HTTP, DNS, DHCP, SSL/TLS, and many others. Wireshark also supports many different types of network interfaces and can capture traffic on wired networks, wireless networks, and even dial-up connections.
How can you use Wireshark to secure your network?
One of the primary ways that you can use Wireshark to secure your network is by identifying potential security vulnerabilities. By analyzing the network traffic, you can identify patterns of suspicious activity or detect unauthorized access attempts. Wireshark can also help you identify vulnerabilities in installed software or network configurations that could be exploited by an attacker.
Wireshark allows you to filter and search network traffic to isolate specific packets that may be related to a security breach. You can use Wireshark to monitor traffic on your network for signs of malicious activity, such as traffic from known malicious IP addresses or traffic associated with known attack signatures.
You can also use Wireshark to monitor your network for compliance with company policies, legal and regulatory requirements. This can include monitoring for unauthorized attempts to access restricted areas of the network, monitoring for the transfer of sensitive data, and monitoring for unusual activity patterns.
In addition, Wireshark can help you troubleshoot issues on your network. By analyzing the network traffic, you can identify the root cause of network problems, such as degraded performance or connectivity issues. Once you have identified the root cause of these issues, you can take steps to fix them and improve the overall security and reliability of your network.
Conclusion:
Wireshark is an extremely powerful tool that can help you secure your network by identifying potential security vulnerabilities and troubleshooting issues. With Wireshark, you can monitor your network in real-time and analyze network traffic to identify patterns of suspicious activity. By using Wireshark to secure your network, you can ensure the integrity and reliability of your network while also ensuring that your organization is fully compliant with applicable regulations and policies.
