Network analysis or protocol analysis is a process performed by network or security professionals of a network in order to get an insight in to network traffic, network services or data flow. The Analysis is performed by capturing or listening the network data.

Familiar with packet flows and packet structure.

Analyzing the whole network bandwidth or delays
Identifying a faulty network device
Testing of firewall or intrusion detection systems.
Performing network audits
Identifying current bandwidth usage of a network or devices.
Classify and define malicious traffic signatures.
Logging or capturing of network traffic for forensic evidence.
Response time evaluation across the network to implement Qos.

How to get rid of CDFS partition from your Flash Drive

Renjith — Fri, 18 Jun 2010 06:13:27 +0000

I was googling to get a solution for how to delete CDFS partition from my Flash drive. It is so annoying when a program autoruns whenever you plug-in your flash drive and instead of the regular driver letter for flash drive one more drive will show up in My Computer. I have tried formatting and used windows disc manager, Fdisk.. It was all in vain! I have seen this CDFS partition in many of the flash drives which is supplied by a product manufacturer. The CDFS partition will actually contain the device driver in those Flash drives. When you buy a Sandisk Cruzer Flash they are providing you a program called U3 which is actually a useful application has capabilities for Drive security, Antivirus, Supports synchronization between your PC and Flash Drive etc, but remember they have used the CDFS technology to bind these application in to the flash drive.

Believe me am not going to tell you how to create a CDFS partition in your Flash drive but let me show you how to delete it.

1.    Download the U3 Removal tool from Sandisk
2.    Before you start the application plug your flash drive
3.    Run the application and you will be prompted like below

4. Click Next to proceed.

5. Select Yes and Click on Format

After formatting if you open My Computer it will no longer display the CDFS partition.

Believe me am still not going to tell you how to create a CDFS partition in your Flash drive but let me show you how to delete it.

Renjith — Sun, 13 Jun 2010 23:42:32 +0000

I have been using Unetbootin to create a Linux bootable Flash drive but recently I happen to use Linux Live USB Creator. I would say it’s the best windows application for creating various Linux’s bootable flash drives. The beauty of this tool is, it has more than 100 Linux distributions with their download link and that will allow you to download the package and let you create a Live Flash Drive. All this in one applications! Easy is n’t it?

The distros are classified in to Ubuntu variants, Fedora variants, Debian variants, PCLinux OS variants, Rescue OS, Gentoo variants, Security purpose Linux and lite Linux variants. It’s a cool package and all most all the great packages in one place.

The Windows supported GUI is giving 5 easy steps to create the Live Bootable Flash Drive.

1.   Choose the Flash Drive
2.   Choose the Source ( Images files, CD, Download)
3.   Persistance ( Giving you option to set the size for persistence when you run the Linux in live mode)
4.   Here you are getting 3 options
a)   Hide files on the flash drive
b)   Format the Drive using FAT32
c)   Installing virtualbox and let you run the Linux on your windows.

The all new Autoruns 9.5 – The best startup manager ever

Renjith — Sat, 09 May 2009 16:32:42 +0000

Microsoft has released the new version of Autoruns 9.5 this week. It has the extra feature to list all the installed codecs in a computer. I could tell you it is an essential tool when I was troubleshooting a virus problem. Let’s see what is this tool all about ( for those who dont know about this wonderful tool) Autoruns will show you what programs are configured to run during system bootup or login, and shows you the entries in the order Windows processes them. These programs include ones in your startup folder, Run, RunOnce, and other Registry keys. You can configure Autoruns to show other locations, including Explorer shell extensions, toolbars, browser helper objects, Winlogon notifications, auto-start services, and much more. Autoruns goes way beyond the MSConfig utility bundled with Windows Me and XP.

The new option which you can find in this tool is the Tab called Codec which displays multimedia codecs “which are gaining popularity as an extension mechanism used by malware gains automatic execution.” This will display all the codes including the windows ones. You can hide all the windows codes by clicking on the Options>Hide Microsoft and Windows entries and verify all the malware codecs.
