Nmap (Network Mapper) is an extremely versatile, open source network analysis tool. It allows you to identify active hosts, analyze services, detect vulnerabilities and manage resources. Everyone in the cyber security department has probably heard of this software - but IT teams are not made up exclusively of "haters." For this reason, we decided to bring the subject a little closer to all intermediates, in order to illustrate the extent to which Nmap's functionalities support enterprise-associated specialists of every area.
What can Nmap do?
The software was created to scan large networks in a short period of time, but it will work equally well for checking individual addresses. Through the use of a number of functions using IP packets, we can learn about the services, platforms and security features found in the network, among other things. In addition to an extensive list of commands, the user has a suite of scripts at his disposal, which allow him to perform complex tests in a fairly straightforward manner. Advanced users can create their own custom scripts, and Nmap itself is available on almost all operating systems - it is this freedom of operation that makes it quite popular.
Despite its many advantages, the software has some drawbacks that may deter those less specialized. IT workers who are unfamiliar with networks may encounter some challenges and problems when using Nmap. Here are some potential difficulties they may encounter:
Interface complexity: Nmap is mainly operated via a command-line interface, which can be problematic for people who have no experience with such tools. Complicated commands and options may require learning and understanding for effective use of the program.
Lack of knowledge of protocols: In order to take full advantage of Nmap's potential, some knowledge of network protocols such as TCP/IP, DNS, HTTP, etc. is required. Lack of knowledge in this area can make it difficult to interpret scan results and understand their context.
Risk of false positives: Nmap scan results can sometimes generate false positives, indicating open ports or vulnerabilities that do not actually exist. Without knowledge and experience, IT staff may make mistakes or overlook potential threats.
Violation of security policies: The use of Nmap and network scanning can potentially violate an organization's security policies. IT employees who are not properly instructed or are not aware of the policies and restrictions can accidentally compromise network security.
The answer to these challenges? Cyberscope!
With a company of several or more than a dozen branches, it becomes impossible, or incredibly expensive, to constantly monitor infrastructure security. Specialists can't be in several places at once - but with Cyberscope they don't have to at all! When we program the tool to suit our needs, anyone, even the least specialized employee, can perform the necessary network security tests - regardless of the location of the SecOps team. Cyberscope from NetAlly is a portable and rugged device that allows you to put Nmap's functionality in your pocket.
