4 Basic Nmap Scan against IP or host Hands On | Nmap For Ethical Hackers

Ethical hacking is a process of detecting vulnerabilities in an application, system, or organization’s infrastructure that an attacker can use to exploit an individual or organization. They use this process to prevent cyber attacks and security breaches by lawfully hacking into the systems and looking for weak points.

Confidentiality, integrity and availability, also known as the CIA triad, is a model designed to guide policies for information security within an organization. The model is also sometimes referred to as the AIC triad (availability, integrity and confidentiality) to avoid confusion with the Central Intelligence Agency.

Network security is the protection of the underlying networking infrastructure from unauthorized access, misuse, or theft. It involves creating a secure infrastructure for devices, applications, users, and applications to work in a secure manner.

What is Nmap ?

Nmap is a free and open-source network scanner created by Gordon Lyon. Nmap is used to discover hosts and services on a computer network by sending packets and analyzing the responses. Nmap provides a number of features for probing computer networks, including host discovery and service and operating system detection.

Some of this tool’s best features are that it’s open-source, free, multi-platform and receives constant updates each year. It also has a big plus: it’s one of the most complete host and network and port scanners available. It includes a large set of options to enhance your scanning and mapping tasks, and brings with it an incredible community and comprehensive documentation to help you understand this tool from the very start. Nmap can be used to

Create a complete computer network map.

Find remote IP addresses of any hosts.

Get the OS system and software details.

Detect open ports on local and remote systems.

Audit server security standards.

Find vulnerabilities on remote and local hosts.

It was mentioned in the Top 20 OSINT Tools article we published, and today we’ll explore a little bit more about this essential security tool with some practical terminal-based Nmap commands.

What is Wireshark ?

Wireshark is a free and open-source packet analyzer. It is used for network troubleshooting, analysis, software and communications protocol development, and education. Originally named Ethereal, the project was renamed Wireshark in May 2006 due to trademark issues.
