Zenmap

Introduction

Zenmap is a graphical user interface (GUI) for Nmap. It can be of great help to start a network scan by simply selecting the options you want. Besides Linux, it also runs on Microsoft Windows, macOS, BSD, and other flavors of Unix.

One of the strengths of Zenmap is the ability to store profiles, which can be reused for later scans. The command creator is another one, which helps interactively create the right nmap commands. Recent scans are stored in a searchable database and scan results can be saved and compared.

Project details

Zenmap is written in Python.

                    Safety

                    Introduction

                    When having applications deployed in your environment, not all of those may be installed via a package manager. When your infrastructure grows, it becomes even harder to know which tools are properly patched and which ones are not. For Python applications, this is where Safety comes in that can help scan installed software components via pip. It will also look at any of the dependencies that are installed.

                                            Is Nmap the best port scanner? ›

                                            Our focus is on Nmap (Network Mapper), by far the most popular tool for network discovery and port scanning. Some of its features include Host Discovery, Port Scan, Service and OS fingerprinting, and Basic Vulnerability detection.

                                            Why is Nmap so popular? ›

                                            Nmap provides a number of features for probing computer networks, including host discovery and service and operating system detection. These features are extensible by scripts that provide more advanced service detection, vulnerability detection, and other features.

                                            What are the weaknesses of Nmap? ›

                                            Nmap has some drawbacks that should be considered before using it. It can be detected and blocked, as it can generate a lot of traffic and noise on the network which can alert network defenders or trigger intrusion detection and prevention systems.

                                            Why is Nmap taking forever? ›

                                            Limit the number of ports scanned. By default, Nmap scans the most common 1,000 ports. On a fast network of responsive machines, this may take a fraction of a second per host. But Nmap must slow down dramatically when it encounters rate limiting or firewalls that drop probe packets without responding.

                                            Should I delete Nmap? ›

                                            Removing Nmap is a good idea if you are changing install methods (such as from source to RPM or vice versa) or if you are not using Nmap anymore and you care about the few megabytes of disk space it consumes. How to remove Nmap depends on how you installed it initially (see previous sections).

                                            How do I scan ports without Nmap? ›

                                            If Nmap is not installed and you do not wish to use all of Nmap options/features, you can use the netcat/nc command for scanning ports. This may useful to know which ports are open and running services on a target machine.

                                            Is Zenmap the same as Nmap? ›
