Cybersecurity is the process of preventing illegal access, theft, or damage to networks, electronic devices, and sensitive data.
Threats such as online security breaches are occurring at an unprecedented rate, posing a huge threat to sensitive and highly confidential information such as financial records, usernames, and passwords.
Access to this data by a cybercriminal invariably leads to serious problems such as the sharing of private information, the selling of data to unaffiliated parties, the alteration of data to fit their purposes, the use of data for financial theft, and more.
A survey shows that cybersecurity threats are growing frequently and at a sophisticated rate. Phishing attacks surged by 48% in the first half of 2022, with reports of 11,395 occurrences costing organizations $12.3 million.
One method to achieve optimal security is to keep an eye out for weaknesses in the IT environment and take action before hackers take advantage of them.
Encrypting network communications, safeguarding systems against assaults carried out through endpoints, and preventing unauthorized access to networks are all aspects of Cybersecurity.
In today’s guide, we showcase the best cybersecurity tools for protecting networks, devices, and data from unauthorized access, theft, and damage.
1. Snort – Network Intrusion Detection System
Library packet capture (Libpcap) is the foundation of Snort. Content matching, packet logging analysis, real-time web analysis, network traffic surveillance, and protocol analysis are just a few tasks Snort can accomplish.
As soon as a threat is identified, the application alerts organizations to the need for preventative action. In addition, there are no licensing fees or software maintenance upgrades needed for this cyber security assessment tool, and it also handles network packet tracking and data streaming to the screen assignments.
With Snort, enterprises can identify potentially harmful threats on their networks and take preventative action to stop attacks before they start.

Along with Nmap, Ncat can be downloaded as part of the regular Nmap distribution packages from the Nmap download page. These packages include source code as well as Linux, Windows, and Mac binaries.
5. John the Ripper – Password Cracker
For good reason, a lot of security enthusiasts love John the Ripper, a system that was initially created for the UNIX operating system. It has subsequently developed into a tool for identifying weak passwords that could compromise a system and is compatible with a variety of other operating systems, including Windows, DOS, OpenVMS systems, and more.
This tool packs advanced features, such as providing a variety of modes for quick password cracking and software that assists in recovering passwords. It also works across 19 distinct platforms.
John the Ripper uses the rainbow table technique to crack passwords, which is used in the majority of cyberattacks. This software takes a sample from a list of words that are commonly found in dictionaries and compares the hashed password to the password in the file that is being matched.
When performing penetration testing activities, the password cracker is mostly utilized. IT specialists utilize this program to identify weak passwords and bad password practices.
6. Nikto – Vulnerability Scanner
One tool for finding vulnerabilities in web servers is Nikto, an open-source, free web server scanner. It can check for issues including out-of-date server software, hazardous files, and other issues. It can carry out both general and server-type specific checks.
You can use this command-line utility to record and print any cookies you receive. It also verifies that the web server software is installed, that numerous index files are there, and that HTTP server configurations exist.
Nikto is the ideal software for general web server security assessments. You can scan multiple web servers fast. The downside to this is that these scans can easily be picked up as intrusions by intrusion detection systems. To carry out covert scans, take advantage of the anti-IDS plugin support.
