Simple — when data packets are transmitted, they pass through several nodes in a network.
If a node finds the packet is addressed to some other node, it drops or ignores the packet. In packet sniffing, on the other hand, some nodes are programmed to not follow this practice and collect all or a certain sample of packets, regardless of their destination.
As mentioned before, a packet sniffer can have both positive and negative use cases, depending on who is using it. Cyber attackers can exfiltrate sensitive information from unencrypted messages. If a user logs into websites over unencrypted transmission his credentials are exposed in plain text and can be easily intercepted by packet sniffers. Making sure all applications and servers within an organization run without any performance bottlenecks is a difficult task.
When an issue occurs, it can be really hard to identify which network or app component caused the slowdown. For this reason, network admins continuously monitor their network for routine maintenance and optimization. With packet sniffers, they can collect information from all points of their network to quickly identify the components responsible for the delay.
It helps in determining the amount of time a packet takes to travel from a sender to a receiver. Additionally, they can identify congested links, detect the apps generating an unusual amount of traffic, and take remedial actions to resolve the issue.
With packet sniffers, teams can get performance metrics for different access points and wireless controllers, correlate network data across the stack and minimize network downtime. Using advanced IP sniffers and packet analyzers, IT teams can categorize the data based on destination server IP addresses, ports involved in communication, traffic volume, and more. This tool is used by security professionals and hackers to bypass security solutions and to access remote computers and devices.
The Havij tool is an very strong SQL injection tool. This tool is used by hackers and security professionals to audit or hack broken and vulnerable SQL environments.
You can download Nmap via the official website, it runs on Windows and Linux. There is also a graphical version called Zenmap. The official Wireshark package can be downloaded here. Wireshark runs on Windows and Linux. Officially you should not be able to download Cain and Abel, but on this site, you will get clear instructions on how to get your hands on Cain and Abel. These tools all have their official publisher linked. I have been in cyber security for over 10 years now, and I can tell you, it is a lifestyle.
On a daily basis, you try to improve your hacking and security skills — you do this by attending conferences, watching online tutorials, keep tracking of CVE and exploits, and I am sure, that you can easily sum up 20 more habits that you must have.
In these years, I have been playing around with various tools, and I have created my own hacking tools. One of the major players, that keeps coming back is nMAP. This tool is easy to use, and it runs on most platforms. Another major name is Metasploit, these guys are doing a fantastic work. Its counterpart, the Network Analyzer , again with a self-explanatory name, is more focused on the traffic itself.
While the Performance Monitor is focused more on the overall view of the network's performance, the Network Analyzer is paying a lot more attention to the network on a more granular level. In particular this part of the program ferrets out the bandwidth hogs and anomalies, sorted by merit of users, protocols, or applications.
Available for Windows environments only. You can start of with a day free trial. The SolarWinds Bandwidth Analyzer Pack is our top pick for a packet sniffer and network analyzer for traffic and data analysis because it presents all of the monitoring tools that you need for a network. This package incorporates a packet sniffer that is able to read the headers of packets to get detailed traffic information. It is also able to use the NetFlow protocol to gather network utilization information.
Tools in the package enable you to implement traffic shaping measures to gain extra value from your network infrastructure. Download: Start day Free Trial. Official Site: solarwinds.
ManageEngine has recently updated is NetFlow Analyzer to give you greater insights in your network traffic and bandwidth to see whats really going on in your networks. With capabilities that allow you to weed out bandwidth hogs and resource heavy applications, you'll be happy to you chose this product over ones that dont give you historical data. This ManageEngine product gives you detailed views into the packets that go through your networks and help you analyze them further.

WireShark is relatively new tool in the broad scheme of network diagnostics, and it does a great job finding a middle ground between raw data and visual representations of that data. It's got a clean UI, plenty of options for filtering and sorting, and, best of all for some of the multi-platform folks, it jives happily on any of the big three in terms of OS.
Add to that the fact that it's open-source and a Free Sniffer and you've got a compelling tool to reach for when you need some quick diagnostics.
Tcpdump is something of an older tool and, to be frank, it looks like it. But there's a certain power in tools that are so cut and dry — it does what it needs to do, does it with as little a footprint as possible, and does it cleanly.
It may be harder for some professionals to weed through the stark tables of data, but in some environments, or on a machine barely running, minimal is best. It has all the functionality you'd want and need from a sniffer — capturing, recording, etc. Tcpdump is often called for due to its sheer reliability and simplicity.
