NT2580 Unit 5 Assignment 1 BitLocker lets you encrypt the hard drive(s) on your Windows 7 and Vista Enterprise, Windows 7 and Vista Ultimate or Windows Server 2008 and R2. BitLocker will not encrypt hard drives for Windows XP, Windows 2000 or Windows 2003. Only Windows 7, Vista and Server 2008 include BitLocker. BitLocker drives can be encrypted with 128 bit or 256 bit encryption, this is plenty strong to protect your data in the event the computer is lost or stolen. Windows 7 extends BitLocker functionality to removable drives, we call that functionality BitLocker to Go. BitLocker to Go gives you the ability to encrypt your thumb drives and even USB hard drives. You even have the ability to enforce BitLocker to Go via Group Policy, this Group Policy can ensure that users can only store corporate data on encrypted drives. BitLocker does not protect the computers contents while Windows is running. BitLocker is built for offline attacks, once the operating system is up and running.
Truecrypt is a source-available freeware application used for on the fly encryption. It can create a virtual encrypted disk within a file or encrypt a partition or the entire storage device. Truecrypt supports windows, OS X and Linux operating systems. It currently uses the XTA mode of operation. Truecrypt used LRW mode in versions 4.1 through 4.3a and CBC mode in versions 4.0 and earlier. TrueCrypt supports parallelized encryption for multi-core systems and, under Microsoft Windows, pipelined read/write operations to reduce the performance hit of encryption and decryption. On newer processors supporting the AES-NI instruction set, TrueCrypt supports hardware-accelerated AES to further improve performance. The performance impact of disk encryption is especially noticeable on operations which would normally useDirect Memory Access (DMA), as all data must pass through the CPU for decryption, rather than being copied directly from disk to RAM. TrueCrypt is vulnerable to various known attacks which are also present in other software-based disk encryption software such as BitLocker. To prevent those, the documentation distributed with TrueCrypt requires users to follow various security precautions.[15] Some of those attacks are detailed below.

A key reason that the early 3.X and 9.X Windows operating systems were not intended for business use is the fact that they use a FAT file system; which are the only file system that is supported by Windows 9.X. According to Wikipedia (2011), “the FAT file systems have very limited security; every user that has access to a FAT drive also has access to all files on that drive. The FAT file systems provide no access control lists and file-system level encryption like NTFS.”…

Another option is a BitLocker , which is a security feature that allows a user or network administrator to lock hard drives. If Kudler Fine Foods has sensitive corporate data on any hard drives, the user or admin can lock the hard drive with a password so that it cannot be accessed. This adds another layer of protection and ensures that the hard drive simply cannot be pulled out of the computer and attempted to be read as a secondary hard drive on another computer. This is a good feature for protecting data, especially for laptops that will be traveling and could potentially be…

First download and install TrueCrypt on your computer. After downloading and installing the application plug in your flash drive into your computer and click Create volume on the application. Now select encrypt a non-system partition/drive. Then it will prompt you to select the volume type, select standard Truecrypt volume. Now will be selecting the drive that you want to encrypt so click on select drive button and search for the flash drive. Now it will prompt you to select the type of encryption, this will be up to you; the default option is AES which stands for advanced encryption standard that has been adapted by the U.S.…

In an age where data transmission over the network has become a vital aspect of communication and information sharing it is very essential to ensure robust data security. Keeping the above fact in mind, we aim to enhance the existing security standards by designing a more efficient Encryption Algorithm. In this paper we propose the idea of using a combination of AES-DES and incorporating it in the Feistal structure. Being a hybrid of two powerful encryption techniques, the algorithm would be an efficient and reliable encryption standard.…
