The Best Network Scanner I Ever Used.

5,0 vor 5 Jahren

Kommentare: Nmap is the first tool i use to scan any network , because i am really used to it and i really like how it works. We use Nmap to scan and find out the computers are connected to our network and find open ports and its been really easy becuase of nmap.

Vorteile:

With a simple scan of our network using Nmap will return all the computers and devices that are in the network. We get all the IP Address of the Computers By Scanning the network. And i really like that we can find open ports in our networks using. There are lots of different types of scan that we can do on our network using Namap, And there is a feature that i like which is we can find out which operating system are they using from their IP Address.

Nachteile:

Nmap is really great. But there is learning curve, It takes time to understand how it works , like we need some time to get used to its commands in order to get the real use out of nmap. Sometimes It takes longer than we expected to finish the scan, but we can alter the commands and change it to some specific type of scanning to make the scan more fast.

Nmap: Time-tested penetration testing tool for network security

4,0 vor 9 Monaten

Kommentare: Great penetration testing tool. A necessary tool to use in any network security discipline.

Vorteile:

I used Nmap to simulate many network attacks on servers and operating systems as part of my cryptography and network security courses. We usually test DoS flooding, fingerprinting, and port scanning attacks to stand on the hardness of a victim server and the vulnerabilities in its operating system and networking stack. Syn flooding attacks using TCP and UDP flooding attacks can be easily tested using basic command in nmap, even constructing customized TCP/IP packet structures can be a very basic task using nmap. I like that nmap is almost present by default in main Linux distributions. It is open-source and can be used after being acquainted with the command structure.

Nachteile:

Would be very glad to see a GUI version for nmap to make using it a bit more facilitated for non-technical people. However, simple references on the different commands in nmap can be found almost everywhere over the internet.

Best network discovery tool

5,0 letztes Jahr

Vorteile:

Nmap has excellent discovery tools and nmap script engine makes nmap the best tool not only for network discovery but also for asset management, for network perimeter security by checking different ports and protocols exposed and for reconnaissance.

Nachteile:

Reporting for nmap can be a lot better as right now it only supports generating XML files. Reporting features must include variety of different formats like printing out a whole network map etc.

Great tool for network or system admin

5,0 vor 5 Jahren

Kommentare: I have used nmap in the past if i found a unknown device on my network i will use Nmap on the corporate lan and scan the machine to get OS info, mac and general information on it. With the MAC i can then go to the switch and track down where it is located in the building.

Vorteile:

The software has so many features and can do so many different things. You can scan for specific Packet types in TCP or UDP you can scan entire ranges or machines for open ports exposing security flaws.

Nachteile:

This program is a BEAST. I took several different classes on using this program as it is extremely powerful and can cause issues if used incorrectly in a production environment and could also be prosecuted legally if the owner of said network chooses too.

NMap: Still the Best Penetration Testing Tool for Network Security

5,0 vor 11 Monaten

Kommentare: Great penetration testing tool. A must know-how for any network security professional.

Vorteile:

Nmap is the penetration testing tool of choice for Network Security Professionals. I used nmap for carrying various ethical hacking attacks on virtualized network systems to support teaching network security and cryptography university courses. nmap is so popular for carrying out DoS flooding attacks using TCP (Syn and Fin Flood attacks) and for port scanning and OS fingerprinting. The stealth scanning mode in nmap is so popular as well and it is very well implemented. Nmap is open source and many customization can be applied to make it more effective and personalized.

Nachteile:

Nmap supports a command line interface with no GUI. This makes it a bit intimidating for beginners and undergraduate students. Although this is not a weakness, I believe that developing a standard GUI interface for nmap would be supporting a better reach to a larger customer base.

Best ever network scanning tool

5,0 vor 3 Jahren

Vorteile:

The tool is very lightweight and simple to install. It is very accurate in detections and provides vulnerability information in a very clear manner that is easy to understand. Can detect open ports of applications and the status of firewall filtering applied for the ports. There are a lot of scripts available to conduct various types of detections. Scans can be conducted quickly. It supports both Windows and Linux platforms. In Linux, it is built into the operating system which is very helpful. This is the ultimate tool for map the network status.

Nachteile:

Nmap GUI needs improvements. Updates are coming quite slowly. Technical knowledge is required to conduct advanced scans. Since this is an open-source tool there is a lack of support. You need to know the commands and required switches in order to conduct a scan. So for the users have a learning curve. Currently, the command line and Zenmap GUI are available. It s better if they can come up with a web-based interface with multi-user architecture.

Nmap Security Scanner for all

5,0 letztes Jahr

Kommentare: Nmap is the best available Security scanner which scans for the open ports and gives us the banner and version information of the devices , Nmap is available in CLI (Command line Interface) and GUI (Graphical user interface) versions for technical and non technical users on various platforms.

Vorteile:

Nmap can be easily customized as per the requirements of the users , we can define the IP ranges and the port numbers to be checked and also store them in the local filesystem storage for the further reference.

Nachteile:

The Nmap generally give the false positives if we increase the no of threads to check the bigger network and we have to re verify the same by scanning smaller parts of the same network for proper results.

Excellent tool for mapping and auditing and searching for vulnerabilities in networks

5,0 vor 6 Jahren

Kommentare: It has allowed me to detect vulnerabilities in the network in a very fast and effective way. like the ports in use in real time and the type of traffic and protocols used by the applications in the company

Vorteile:

* It's easy to use. * It's free. * Reliable with more than 17 years in the market. * It has extensive documentation and excellent support from the user community * Its latest version allows to perform pentesting tasks * It allows to audit the network to know its vulnerabilities: open ports, connected, wireless and wireless equipment. * Sneefer functions * It has multiple security tools that allow audits of passwords, scan the web, exploits, etc.

Nachteile:

* It is an excellent work tool for professionals in the area of networks I do not find defects or negative aspects. only that I see it more for advanced users since it runs on linux operating systems and through the use of commands preferably.

open source tool that work fine

5,0 vor 4 Jahren

Kommentare: There are multiple benefits that we obtain by implementing this software, especially as a network administrator, since we can quickly perform scans and store them for study; you can design different subnets and easily know which teams are recognized. I feel safe to use the software because it is kept up to date and its scripts work according to the use of new technologies.

Vorteile:

The main advantage offered by this software is its ability to adapt to any operating system; especially in the area of network security since in the same infrastructure it will recognize open ports and many other functions without limits.

Nachteile:

What I don't really like is that the software contains such powerful tools to carry out, for example, a port vulnerability scan, and then we can detect that unknown computers are using privileges and these results can be used to hack a network; so I don't know to what extent it is legal

Pentestor Review while port scanning

4,0 vor 5 Jahren

Kommentare: The overall experience is great, I usually use Nmap when it comes to scanning for a white box pentest. Sometimes I use it for BlackBox as well in stealth mode and modified commands of course not the presets.

Vorteile:

The most that I like it's easy to use, the GUI Nmap is really simple and straight forward. I have used the GUI in the begging and helped me a lot to work faster. And the profiling is even better.

Nachteile:

It is the same as in the GUI and the command line the output is a bit too messy and difficult for the eye to follow. It's not a big deal since I know each section and what where to expect. It would be great if there was a better structure,

Excellent program of open code that serves to carry out tracking of ports in a computer

5,0 vor 6 Jahren

Kommentare: highly recommended for people who want to know about hacking techniques

Vorteile:

This program even in its graphic versions is very powerful, and has options to make scans very difficult to detect by victims or network supervisors. Scan any range of ports you want and even detect the victim's operating system, causing the hacker to identify more clearly how to access the remote computer

Nachteile:

While it is more complex is the type of scan you want to perform, the scanning process can be slower and take several minutes before the end, the speed of the scan depends basically on 3 factors, speed of the scanner's computer (hacker) , latency in the network (if the network is slow or fast), and speed of response and security measures of the scanned computer (victim)

The Standard Network Scanning Tool

5,0 vor 6 Jahren

Vorteile:

I use Nmap very frequently for Information Security Consulting Services and Penetration Testing. It is an invaluable software tool for any information security professional. The level of detailed data you are able to obtain with it is unmatched to similar tools on the market.

Nachteile:

Thre is nothing to complain about this tool, you can't go wrong with it. However, you do require some background technical knowledge and are required to do a lot of reading to understand how it works. You can use it for a long time and still not take advantage of its full potential.

Amazing tool for enumerating apps/networks

5,0 vor 4 Jahren

Kommentare: We use Nmap for every pen test, or network enumeration scan to get an assessment on the network we're working on.

Vorteile:

Nmap just works, it's become the standard for enumerating any box/server/wep app. It works well, and in most cases, returns results fairly quickly (Also depending on your settings).

Nachteile:

There's a tiny learning curve if you're not familiar with the command line (since there's no GUI for Nmap) - So you'll definitely have to take some time learning the commands/options.

The Best and Most Powerful Network Mapping Tool I've Ever Used

5,0 vor 6 Jahren

Vorteile:

We use this software around the office for maping out what IP addresses go to which machines. It tells us the MAC address, tells us what ports are open, closed, what OS the unit is running, and and we can have it specify what range of addresses to look for. We used it to figure out that we had a rarely-used thin client on the network that downloaded a ton of packets (thanks Untangle!) and was being used for non-clinic purposes. It's pretty fast too, our clinic has 20-45 devices on it at any given time, and a complete scan took about 5 minutes.

Nachteile:

It is a bit utilitarian, which is nice for conservation of resources, but a little more of input information would be nice in the "Target" box. Took a little bit to figure out exactly what to ask for and how. For example, for a range of IP addresses to check, you need to type out your request with a dash, like 192.181.1.1 - 120. It just took a little tinkering. In fact, it has so many EXTRA features, sometimes it can be confusing as well.
