Nmap a Hacker Tool for Security Professionalsby Justin Hutchens. The notion of the ethical hacker has always been an ironic one. The developing trends of ethical hacking and offensive security have transformed the information security industry into one of the most self perpetuating industries in the world. The software and tools that are used to secure vulnerable information assets are the same tools that can be used to exploit them. Perhaps its the other way around.

In this excerpt from Digital Forensics Processing and Procedures, the authors provide insight on areas that will need to be considered while setting up a forensic.

I suppose this is a debate that could go on forever and is really just another instance of what came firstthe chicken or the eggThe purpose of this essay is not to discuss the philosophical question of intent. My intentions are more modest. I merely seek to justify the importance of a tool that has been consistently labeled as malicious hacking software. The tool that I am referring to is Network Mapper, or nmap for short. Whether you are a crazed rogue agent that is bent on inciting global revolution or a network security professional hopefully the latter, rather than the former, nmap should have a permanent place in your toolkit. Perhaps, instead of hurling criticism at an extremely functional networking tool, we should hold individuals accountable for their actions and reflect upon the well known Benjamin Parker caveatwith great power, comes great responsibility. Despite some claims to the contrary, nmap is not malicious software. And I think the only reason that it is often labeled as such is because of its very impressive list of capabilities. Despite its potential to do harm, nmap can certainly play an important role in securing a network infrastructure within a professional environment. Nmap has steadily evolved over the years from a simple scanning utility into a full blown penetration testing platform. It can be used in every step of the security auditing process, to include network discovery, port scanning, service enumeration, vulnerability mapping and even exploitation. Throughout this article, I will discuss the capabilities of nmap as they pertain to each step in the penetration testing process. Installation and Preparation. Obviously, prior to using nmap, it is important to have a functional version installed on the system that you are using. Cloud computing providers must develop cloud forensics strategies and adapt their environments for government investigations and digital evidence analysis. Oftentimes, a single cause of failure cannot be identified. The failure may have resulted from a combination of several factors that may be related to the list.

Now a days, computer or digital forensics is a very important because of crimes related to computer, Internet and mobiles. Evidences such as computer and digital. By default, nmap is already installed on most penetration testing and network security operating systems such as Kali Linux, Backtrack, DEFT, Node Zero, Security Onion and NST. However, it can also be loaded to nearly any platform of your choice. Nmap can easily be installed on all commonly used operating systems to include Windows, Linux and OSX. There is also documentation available for installing it on more obscure platforms to include BSD, Solaris, AIX and Amiga. OS. Installation packages and instructions on how to perform the install on any of these systems can be found at http nmap. Zenmap Graphical Interface. In addition to the traditional command line interface for nmap, there is also a graphical front end interface called Zenmap. Zenmap is also integrated into many of the different penetration testing platforms previously discussed. However, it is not installed by default in Kali Linux the platform that I will be using for this tutorial. Fortunately, it is in the installation repository and can easily be installed with a single command apt get install zenmap. Zenmaps point and click interface not only effectively streamlines what would otherwise require complicated commands but it can also be an extremely useful tool for learning how to use nmap. It uses profiles to save commonly used scan configurations for later modification andor use. Take a look at the image of the Zenmap interface that is provided in Figure 1 and we will briefly address each of the components. Figure 1. Zenmap Graphical Interface. The first component is the Target field Figure 1. A. This field is where you can specify the remote systems that you want to run a scan against. You can enter a single IP address e. IP addresses e. g. CIDR notation to specify a desired subnet e. The second component is the Profile field Figure 1. B. You can click on the drop down arrow to the right of this field to see several pre configured profiles for scanning. Profiles allow you to save commonly used scan configurations for future use. You can also create profiles of your own and they will then appear in this list well discuss how to do this later in this article. The third component is the Command field Figure 1. C. This field will indicate the command that is going to be sent to the backend. To launch the command appearing in this field, you simply click the Scan button. You can modify the value in this field directly however, it will be automatically populated based on the values of the Target field and the selected profile. If you are new to nmap, you should pay close attention to this field, as it will provide you with a better understanding of the appropriate syntax and use of different nmap commands. The fourth component is the HostService list Figure 1. D. Once you have performed scans, information will be populated in this list. If you have the Hosts button selected, all discovered host IP addresses will be listed. And if you have the services button selected, all discovered network services will be listed. The final component Figure 1. E is where you can sort through all of the information that has been produced by all the scans that you have performed. The Nmap Output tab will display the exact output that would be provided if the command had been entered from the command line interface. The PortsHosts tab content will vary depending on if you have the Hosts or Services button selected for your list. If the Hosts button is selected, then the information under the PortsHosts tab will reflect the services that were identified on the actively highlighted IP address in the list. Otherwise, if the Services button is selected, the information under the PortsHosts tab will identify all hosts that were found to have the particular service that is highlighted in the list. The topology tab will provide a graphical representation of the logical topology of the network, to include all hosts that have been discovered by scanning. It will use returned TTL Time To Live values to display the logical orientation of hosts, relative to one another. The Host Details tab is where you will find the bulk of information that has been discovered about a selected host. This information includes MAC addresses, IP addresses, open ports, identified services, operating system information and any additional information that has been collected. Finally, the scans tab will provide a history of scans that have been performed during the session. At the top of the screen you will see several different drop down menus to include Scan, Tools, Profile and Help. The Help menu is self explanatory. The Scan menu contains options to create new scans, save scans or open previously saved scans. The Tools menu provides some additional functions that can be used to sort through and organize information collected during your scans. And the Profile menu provides options to create new scan profiles or edit existing profiles. Modele Tricotaje Manuale there. We will now briefly discuss how to create a new profile and then launch a scan using that profile.
