It can also check server configuration items such as the presence of multiple index files, HTTP server options, and will attempt to identify installed web servers and software.
Nikto is designed for speed rather than stealth. It will test a web server in the quickest time possible. But its passage will show up in log files and be detected by intrusion detection and prevention systems. For many security professionals, Nikto is a basis of the vulnerability scanning routine.
Snort is one of the best-known open-source intrusion detection system (IDS). It was created in 1998 and it has been owned by Cisco System since 2013.
This tool has three modes of operation: sniffer, packet logger, and network intrusion detection. The sniffer mode is used to read network packets and display them on the screen. The packet logger mode is similar but the packets are logged to the disk. The intrusion detection mode is the most interesting. The tool monitors network traffic and analyzes it against a user-defined rule set. Different actions can then be performed based on what threat has been identified. An enterprise-grade open-source IDS is compatible with any OS and hardware.
Snort can be used to detect different types of probes or attacks. Such probes and attacks including operating system fingerprinting attempts, semantic URL attacks, buffer overflows, server message block probes, and stealth port scans. Snort’s ease of configuration, rules’ flexibility and raw packet analysis make it a powerful intrusion detection and prevention system.
An excellent network protection software testing tool for identifying a security risk before it becomes a security breach. This program contains some useful tools for running security test. These include a web spider, traffic recorder and vulnerability scanner. Paros Proxy can be introduced as Java-based web proxy. This is an excellent program because of its feature to identify network intrusion openings to some of the most common threats. These include SQL injection and cross-site scripting. Anyone who can write a web application can edit Paros Proxy.
This is one of the best open source, free, powerful security programs available. While TrueCrypt having gone years without update, it is still popular. It abandoned by its developer but it is still a strong tool. TrueCrypt is a disk encryption system, allows for layered content encryption with two tiers of access control. It’s easy to see why TrueCrypt remains popular despite not having been updated in four years.
It is just a tool to ensure privacy on the Internet. Although there are malicious exit nodes used to sniff traffic, this isn’t a significant concern with careful use. The system routes requests to proxy web servers for privacy, making users harder to track. Some yeas ago, when people started talking about the “dark web,” Tor gained a lot of press. Tor’s applications in InfoSec are more plentiful than its applications in cybercrime.
This tool is necessary for many office settings because it can be used in identity and account management. KneePass gives users the opportunity to access all of their accounts by using one password. So we can say that it is a simple password management system. Ones who have dealt in InfoSec for more than a day know how important this can be.

This open-source tool, is the original packet sniffer. First released in 1987, it has since been maintained and upgraded but remains essentially unchanged. At least it it unchanged in the way it is used. This is a Mac, Windows and Linux tool.
It captures all traffic on the specified interface and dumps on the screen. This is similar to Snort’s sniffer mode. Although Tcpdump is not the newest packet sniffer available, it set the standard in the field. Tcpdump remains a favorite network sniffer with ongoing active development and clean approach. The tool uses fewer system resources than competing options and opens little security risk.
Tcpdump’s key strength is the possibility to apply capture filters and to pipe its output to grep, another common Unix command-line utility, for even more filtering. Someone with a good knowledge of Tcpdump, grep, and the command shell can easily capture precisely the right traffic for any debugging task.
The world of security can be complicated. The importance of a secure network security system can’t be emphasized enough.
Although these network security tools will not cover every possible scenario, they provide a strong foundation.
The more tools an InfoSec professional has to work with, the better they will be able to address the task at hand. Having access to a wide range of computer network security tools is only the start. Knowing how to put them to use, is the essence of network protection.
