ARP attacks and ARP flooding are common problems small and large networks are faced with. ARP attacks target specific hosts byusing their MAC address and responding on their behalf, while at the same time flooding the network with ARP requests. ARP attacks are frequently used for ‘Man-in-the-middle‘ attacks, causing serious security threats, loss of confidential information and should be therefore quickly identified and mitigated.

During ARP attacks, users usually experience slow communication on the network and especially when communicating with the host that is being targeted by the attack.

In this article, we will show you how to detect ARP attacks and ARP flooding using a network analyzer such as Colasoft Capsa.

Colasoft Capsa has one great advantage – the ability to identify and present suspicious ARP attacks without any additional processing, which makes identifying, mitigating and troubleshooting much easier.

Download your copy of Colasoft Capsa and discover how easy it is to identify network & security related problems.

The Diagnosis tab provides real-time information and is extremely handy in identifying potential threats, as shown in the screenshot below:

Figure 1. ARP Scan and ARP Storm detected by Capsa’s Diagnosis section.

Under the Diagnosis tab, users can click on the Events area and select any suspicious events. When these events are selected, analysis of them (MAC address information in our case) will be displayed on the right as shown above.

In addition to the above analysis, Capsa also provides a dedicated ARP Attack tab, which is used to verify the offending hosts and type of attack as shown below:

Figure 2. ARP Attack tab verifies the security threat.

We can extend our investigation with the use of the Protocol tab, which allows us to drill into the ARP protocol and see which hosts MAC addresses are involved in heavy ARP protocol traffic:

Figure 3. Drilling into ARP attacks.

Finally, double-clicking on a MAC address in the ARP Protocol section will show all packets related to the selected MAC address.

When double-clicking on a MAC address, Capsa presents all packets captured, allowing us to drill-down to more useful information contained in the ARP packet.

Figure 4. Drilling-down into the ARP attack packets.

By selecting the Source IP, in the lower window of the selected packet, we can see the fake IP address 0.136.136.16. This means that any host on the network responding to this packet will be directed to an incorrect and non-existent IP address, indicating an ARP attack of flood.

If you’re a network administrator, engineer or IT manager, we strongly suggest you try out Colasoft Capsa today and see how easy you can troubleshoot and resolve network problems and security threats such as ARP Attacks and ARP Flooding.

Capsa network analyzer review from wireshark.com.

Capsa is a powerful network analyzer for Ethernet analysis, troubleshooting and monitoring. Not only does it provide users with a series of powerful features that help them learn more about improving network security, pinpoint network issues and monitor network activities, but it also features a user-friendly interface that makes using it a breeze. The software is generally targeted at computer professionals and/or teachers who want to learn more about networking technology, protocols, monitoring and security.

Real time monitoring

As a packet sniffer, Capsa is capable of real time packets monitoring and can also presents the data visually by using logs and a GUI for future reference. Given the fact the software is capable if easily analyzing and diagnosing problems on a network, it can tell the user in minutes what is causing it to be slow or if there is an attack that may be the culprit for its poor performance.

In identifying network issues, Capsa can find the top ten local hosts that slow down the network and can also detect whether someone is using a Bit torrent client to download files off the web which is obviously a prime cause of slow network performance.

Safety and security

Should an attack be responsible for the network’s poor performance, the software will immediately locate the packet info and source codes from the host so that the admin can promptly begin investigating the issue. There are 2 types of worms the software can locate, including operating system works and E-mail worms. This functionality is paramount in identifying the infected computers which eventually allows the admin to fix these issues.

Available filters

In order to be able to focus on specific packets, administrators can use a wide range of filters right from Capsa’s dashboard. For instance, admins can monitor real time messages, http requests, E-mail messages and more of the 4 most popular IM apps including YM, ICQ, AIM and MSN.

Other features

There are of course many other features that Capsa incorporates, such as the ability to generate reports of a certain group or global networks automatically, but also customize the data on different charts. As a network administrator, you can also use the software to remotely monitor traffic by installing the application on the business network (on a workstation of course) and using the Remote Desktop Access function.

Conclusion

All in all, Capsa is by far one of the most reliable and simply the best network analyzers out there. Not only does it offer a wide range of improvements that make using it a breeze, but it makes it very easy for anyone who uses it to find the info they need. On top of that, thanks to functions such as reports, Matrix and Diagnosis, it definitely stands out from the large crowd of similar programs available today.

Troubleshooting network problems can be a very difficult and challenging task. While most IT engineers use a network analyzer to help solve network problems, whenanalyzing hundreds or thousands of packets, it can become very hard to locate and further research conversations between hosts. Colasoft’s Capsa v8 now introduces a new feature that allows us to highlight-colorize relevant IP conversations in the network based on their MAC address, IP Addresses, TCP or UDP conversations.

Download your copy of Colasoft Capsa v8 and discover how easy it is to identify network related problems.

This great new feature will allow IT engineers to quickly find the related packets of the conversations they want to analyze emphatically, using just a few clicks.

As shown in the screenshot below, users can colorize any Conversation in the MAC Conversation View, IP Conversation View, TCP Conversation View and UDP Conversation View. Packets related to that Conversation will be colorized automatically with the same color.

Take TCP conversation for example, choose one conversation, right-click it and choose “Select Conversation Color” in the pop-up menu:

Figure 1. Selecting a Conversation Color in Capsa v8.0

Next, select the color you wish to use to highlight the specific conversation:

Figure 2. Selecting a color

Once the color has been selected, Capsa will automatically find and highlight all related packets of this conversation using the same background color:

Figure 3. Colasoft Capsa automatically identifies and highlights the conversation

The relevance between a conversation and its packets is enhanced by colorizing packets which greatly improves analysis efficiency.

If you’re a network administrator, engineer or IT manager, we strongly suggest you try out Capsa and see how easy you can discoverand resolve network problems.
