Free Mac Scanner Software: Colasoft Mac Scanner Reviewed By ilovefreesoftware

May 17th, 2016 No comments

Below is the Colasoft Mac Scanner review from ilovefreesoftware.com

Colasoft MAC Scanner is a free network scanner software for Windows. It can scan all the ports of your local network for connected devices. It can provides you the details such as: IP Address, MAC Address, Host Name, Workgroup, and Manufacturer.

It provides the details in tabular format, and you can easily export the data to txt or csv format. The program is helpful for Network Administrators to maintain a list of Network assets. You can easily check who is using your network.

How to Scan Network for Connected Devices using Colasoft MAC Scanner:

It is very easy to use this tool to scan the entire network, and find details of all the connected devices.

You can click Start button on the main toolbar or press F5 key from your keyboard to start the scanning process. You can run it from Start Menu Run command also by typing “csmac” and pressing Enter key. It automatically detects all the Local Subnet list or you can click Refresh from the Local Subnet dropdown. It takes just a few seconds to scan the entire network, and keeps showing details of the devices while scanning.

Once the scanning is complete, you can export the list of connected devices. You can export the list in  .TXT, or .CSV  format, and also in its native .CSCNTAB (Colasoft Name Table File).

The size of the program is just 6.79 MB and it can works with almost every Windows version.

If you want to export only some records for later reference; you can do this too by selecting the records you want and click the Export Selected button on the main toolbar or use context menu command to do so.

 

More commands like Copy, Delete, Find are also there in the Default toolbar and in the Edit menu. Also if the scanning process is taking much time, you can then Pause or Stop the process any time by pressing the desired button.

Another interesting feature of this software is that it also lets you specify number of threads that can be used for scanning. You can choose between 1 to 100 threads. More the number of threads, faster will be the scanning performance.

Limitations of this software:

Despite being good at what it does, this software comes with its limitations and drawbacks as well. First of all, the documentation of this software talks about some features, which are actually not available in the free version. Secondly, I tested this software multiple times, but it never gave me the “Manufacturer” information.

Get Colasoft Mac Scanner.

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.
