    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.

                    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.
