Colasoft Announces Release of nChronos Network Analysis Appliance v5.1

April 27th, 2016 No comments

April 26, 2016 – Colasoft (www.colasoft.com), an innovative provider of powerful and affordable network analysis solutions, today announced the release of its flagship product Colasoft nChronos Network Forensic Analysis Appliance v5.1. With the packets of user-defined applications can be stored with truncated length now, the storage and retrieval performance are greatly improved. In addition, HTTP packets reconstruction and packets replay link are now available in nChronos 5.1, allowing network managers to easily monitor network activities and replay packets for abnormality diagnosis.

People have attached more and more importance to the security of the web information. While as the central protocol of web’s application layer, HTTP forms the foundation of it. Colasoft nChronos 5.1 provides an HTTP packets reconstruction feature, which can show which web pages that an endpoint visits. If you select an IP address, nChronos can reconstruct the web pages that it visits. You can see how the page looked exactly. By exactly recording who have visited where and when, it is particularly suitable for executives to supervise the employees’ web browsing at work, and record the time and web sites they visited for future reference.

Sometimes we need to see the proof details to define the root cause when there is abnormality on the network, especially when we need to define the problem is related to network or to application. With nChronos 5.1, you can view the packet details very quickly, without opening the complete Expert analyzer. Just select the interested traffic and click “Decode Packets”, you can load Expert Analyzer to decode packets down to protocol fields.

Other new features in nChronos v5.1 you will find:

  • IP segment based virtual interfaces support.
  • Truncated packets can be analyzed with original length.
  • DPDK support.
  • System monitor information can be sent as syslog.
  • VXLan protocol support.
  • A VXLan statistical view is provided.
  • nChronos service can be restarted on nChronos Server web page.

“Some most requested features return in nChronos v5.1,” said Eddie Gao, CTO at Colasoft, “Previously, we took each change separately and drilled down to determine why it’s beneficial. We are always on the way to be better.”

An evaluation version of nChronos 5.1 is available for download at http://www.colasoft.com/download/products/nchronos.php

Detect Brute-Force Attacks With nChronos Network Security Forensic Analysis Tool

March 29th, 2016 No comments

Brute-force attacks are commonly known attack methods by which hackers try to getaccess to restricted accounts and data using an exhaustive list/database of usernamesand passwords. Brute-force attacks can be used, in theory, against almost any encrypted data.

When it comes to user accounts (web based or system based), the first sign of a brute-force attack is when we see multiple attempts to login to an account, therefore allowing us to detect a brute-force attack by analyzing packets that contain such events. We’ll show you how Colasoft’s nChronos can be used to identify brute-force attacks, and obtain valuable information that can help discover the identity of the attacker plus more.

For an attacker to obtain access to a user account on a website via brute force, he is required to use the site’s login page, causing an alarming amount of login attempts from his IP address. nChronos is capable of capturing such events and triggering a transaction alarm, warning system administrators of brute-force attacks and when the triggering condition was met.

CREATING A TRANSACTION ANALYSIS & ALARM IN NCHRONOS

First, we need to create a transaction analysis to specify the pattern/behavior we are interested in monitoring:

From the nChronos main page, first select the server/IP address we want to monitor from the Server Explorer section.

Next, from the Link Properties, go to the Application section and then the Analysis Settings as shown below:

colasoft-nchronos-brute-force-attack-detection-2a

Figure 1. Creating a Transaction Analysis in nChronos (click to enlarge)

Now click the button of New Web Application (second green button at the top) to set a Web Application, input Name and HTTP Hostname, then check the box labeled Enable Transaction Analysis and add a transaction with URL subpath e.g “/login.html”.

Proactively monitor your network 24/7 for attacks, suspicious network traffic and problems – Download nChronos now!

At this point we’ve created the necessary Transaction Analysis. All that’s required now is to create the Transaction Alarm.

To create the alarm, click Transaction Alarms in the left window, input the basic information and choose the parameter of Transaction Statistics in Type, and then set a Triggering Condition as needed, for example, 100 times in 1 minute. This means that the specific alarm will activate as soon as there are 100 or more logins within a minute:

colasoft-nchronos-brute-force-attack-detection-3a

Figure 2. Creating a Transaction Alarm (click to enlarge)

Finally, you can choose Send to email box or Send to SYSLOG to send the alarm notification. Once complete, the transaction alarm fordetecting brute-force attack is set. When the alarm triggering condition is met an email notification is sent.

Note that the specific alarm triggering condition does not examine the amount of logins per IP address, which means the alarm condition will be met regardless if the 100 login attempts/min is from one or more individual IP addresses. This can be manually changed from theTransaction Analysis so that it shows the login attempt times of each individual IP address.

Below is a sample output from an alarm triggered:

colasoft-nchronos-brute-force-attack-detection-3a

Figure 3. nChronos Brute-Force alarm triggered – Overall report (click to enlarge)

And below we see the same alarm with a per-IP address analysis:

colasoft-nchronos-brute-force-attack-detection-4a

Figure 4. nChronos Brute-Force alarm triggered – IP breakdown (click to enlarge)

The article shows how nChronos can be used to successfully detect a Brute-Force attack against any node on a network or evenwebsites, and at the same time alert system administrators or IT managers of the event. If you’re a network administrator, network engineer or IT manager, we strongly suggest you try out Colasoft nChronos today and see how easily you can troubleshoot network problems, proactively obtain alerts on unusual network traffic and monitor your network around the clock.

HOW TO DETECT ARP ATTACKS & ARP FLOODING WITH COLASOFT CAPSA NETWORK ANALYZER

November 10th, 2015 No comments

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-middleattacks, 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:

capsa-network-analyzer-discover-arp-attacks-flooding-1

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:

capsa-network-analyzer-discover-arp-attacks-flooding-2

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:

capsa-network-analyzer-discover-arp-attacks-flooding-3

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.

capsa-network-analyzer-discover-arp-attacks-flooding-4

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.

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

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.
