With so many open source tools available to help with cybersecurity, it can be tricky to figure out where to start, especially if you are an IT generalist who has been tasked with security.
In this article, we will provide an overview of some of our favorite open source tools as well as tips on how to use them for cybersecurity.
- Cyber Security Tools
The Cybersecurity mechanism delivers a specific series of Free and Open Source Software (FOSS) and these cybersecurity devices are well ordered by functionality (Encryption, Anti-virus, Email Protection, Internet security, etc.) and unspecified target designs. The open source software tools may be free while analyzing FOSS but it’s subject to source licensing constraints, and the free software tools might be free under closed source. The open source cybersecurity tools having thousands of security capabilities both defensive and offensively.
Some of the significant security tools are being helpful to secure the systems and networks. The following are some of the open source security tools that have indispensable categorization due to the fact they are very productive, well sustain and it is easy to get start.
- Networking and Operating System Hardening
Hardening of the OS is the “act of configuring an OS securely, updating it, creating rules and policies to help govern the system in a secure manner, and removing unnecessary applications and services”. Hardening is done to lessen the computer OS vulnerability to menace and to lighten viable risks.

A network security audit is a process for evaluating the effectiveness of a network's security measures against a known set of criteria. These audits typically look at a number of things that include: Hardware Configuration, Software Configuration, The Environment, Information Handling Processes and User Practices.
NMAP stands for Network Mapper. It is a utility that provides information about the available ports (connection points) on the network. And it has excellent OS and server software version detection. This tool analyzes IP packets to gain a ton of information about systems including: the services running on the system, operating system, presence and type of firewalls, and more.Figure 4: NMAP
Zenmap - a free open source GUI invent to be utilized with Nmap. Zenmap is multi-platform tool which supports “Linux, Ubuntu, Mint, Kali, Fedora, CentOS, Windows, Mac OS X, BSD and so forth”. Beginners can also use the Zenmap to discover vulnerabilities and to scan networks.Figure 5: ZENMAP GUI
HPing is a “TCP/IP packet assembler/analyzer and furthermore a command-line oriented”. This interface is innovative to the ping(8) unix command, yet HPing are not just ready to send the echo ICMP requests. It additionally supports protocol, for example, TCP, UDP, ICMP and RAW-IP. It has the mode called “traceroute” mode, which have the “capacity to send records between a secured channel, and numerous different highlights”.Figure 6: HPing
- CyberSecurity Frameworks and Operating Systems
The cybersecurity framework makes our data and system safe. Habitually it in scripts the intention of overall security of an organization’s moderately focusing especially on IT module. Most cybersecurity frameworks are intended to improve the existing security infrastructure already in place.
- Kali Linux
Kali Linux is THE go to operating system for professionals doing any kind of work around cyber security. The operating system comes ready to go with every cybersecurity tool and capability needed to perform any kind of security work. All of the apps installed are open source. It is one of the free cybersecurity tools that I couldn’t live without.
Qubes is Free and Open Source Software (FOSS) and security focused operating system. It provides security by the utilization of compartmentalization. Components of the OS and apps are compartmentalized into qubes. It also allows for the running of Windows apps on Windows App VMs.Figure 7: Qubes OS – First Look
Metasploit is probably one of the most well known and used penetration testing frameworks. Rapid7 calls it “The world’s most used penetration testing framework.” The framework includes a ton of exploits and payloads that you can use across all systems to gain access.Figure 8: Metasploit Project
- Kali Linux
- Internet Security
Typically, Internet security bounds with browser security, where secured data’s invade through the Web form, and the Internet protocol sends the overall authentication and protection to the datas. Internet security is a boundless concern casing all the catch term security for transactions made over the Internet.
