A body of the technologies, processes and practices that are designed to prevent the unauthorized access to the networks and data is known as cyber-security. A professional who creates secure network solutions to save from these kinds of cyber-attacks is known as a cyber-security engineer. There are various roles and responsibilities of a cyber-security engineer. He has to work for the security of the data within an organization. He has to evaluate the security requirements of an organization. In the case of a security breach, he has to respond promptly. He has to take an active part in the investigation of a security breach and much more. To fulfil these responsibilities, a cyber-security engineer has to use some tools.
Here, we will discuss the top five tools that a cyber-security engineer must know.

Wireshark
As a cyber-security engineer, you will have to analyze various networks. Wireshark is the best network analysis tool for cyber-security engineers. It is an open-source tool. This tool allows the cyber-security engineers to inspect the real-time data on a network. It is also the best tool to dissect the data in the form of frames and segments. As a result, you can get useful information about the bits and bytes within the packet. You can easily use this tool on all the major network protocols. As a cyber-security engineer, if you are working in a public network, you can use this tool as a packet sniffing tool.
By using this tool, you can do deep infection of the hundreds of protocols. It is providing the opportunity to live and offline analysis. The cyber-security engineers can run this tool on multi-platforms like Windows, Linux and macOS etc. It is known as the most powerful analysis tool in this field because it is providing the facility of rich VoIP analysis to the users. It is also providing the facility of decryption support for many protocols. For quick and intuitive analysis, you can apply the colouring rules. After analyzing a network, you can show its output in the form of XML, CSV or plain sheet.

Nmap
It is a network mapping and port scanning tool. That’s why it is the best tool for penetration testers. It is also one of the most popular tools among malicious hackers. By using this tool, malicious hackers perform network scanning. As a result, they can get useful information from your network. They can get a clear picture of the network topology.
They can get useful information about the machines that are connected with this network. They can also get useful information about the versions of the operating system. At last, they also find useful information about the vulnerabilities that are present in the network. Cyber-security engineers can also use this tool for their benefits.
They can use this tool as a network scanner. While using this tool as a network scanner, they can get useful information about the targeted network. Lots of other penetration testers are also available for the cyber-security engineers.
The most important aspect of this penetration tester tool is that it is simple, flexible and extensible. It is offering a simple command-line interface for the users. By using this simple command-line interface of this tool, the cyber-security engineers can easily add a few flags to choose different types of the scans.
Netcat
Recommended by a dissertation help firm, now this tool is also known as Ncat. In the networking field, this tool is referred to as a Swiss-army knife. A cyber-security engineer should also have enough information about this tool. Its reason is that it is the best tool for cyber-security engineers to view and record the data. They can view and record the data in the form of TCP or UDP network connections. You can also use this tool as a back-end listener.
As a back-end listener, this tool works as port scanning and port listening tool. You can use this tool to check full DNS forward and reverse checking. This tool has also the ability to use in any kind of local source port. This tool has also built-in port scanning capabilities. This tool has also maintained an active community. By taking part in this active community of this tool, you can find out the best possible solutions to your problems.
Metasploit
It is also an open-source penetration tester tool for the users. This tool is providing a complete framework that you can use during your penetration testing life-cycle. This tool is also very famous among the community of cyber-security professionals. The cyber-security professionals can use this tool to develop and execute the exploit code against the remote target machine. This tool has also some built-in tools.
By using these built-in tools, you can perform lots of activities. Security professionals can conduct penetration tests. They can verify the patch installations. They can also use this tool for regression testing. This tool is also very famous among the hackers’ community. Its reason is that they can also use this tool to conduct various attacks.
By using its Ruby programming language, the hackers can use this tool to build and test the exploits. This tool is available in the form of a command-line tool. It means that you can easily perform the required tasks by using different commands on this tool.
Burp Suite
While working as a cyber-security engineer, you will have to pen-test lots of applications. Burp Suite is the best tool that you can use to pen-test the applications. Cyber-security engineers can also use this tool for web app security research. Burp Suite has also lots of built-in tools. By using these built-in tools of this tool, the cyber-security engineers can use it for web application testing life-cycle. It means that cyber-security engineers can perform all the tasks from scanning to the exploitation of web applications. You can also use this tool to break into web applications.
As a cyber-security engineer, you can also use this tool to intercept the HTTP requests. While intercepting the HTTP requests, this tool manipulates the requests and responses of the web applications.
