128-bit

Encryption is not required

If you are concerned about information security, wireless security protocols add some small level of protection. If you are not concerned about it then encryption is an extra level of hassle.

Assuming you have the filesystem mounted, the "mount" command can tell you every mounted filesystem and its type.

Only when sharing the filesystem with another Linux system that uses an older filesystem such as ext2.

Filesystem Hierarchy Standard was created on 1994-02-14.

You need root privileges, and it's often best not to use fsck on a live (mounted.) filesystem. Also you'll need to know the device file and, in some cases, the filesystem of the partition you're working on. The command is thusly:

# fsck /dev/sdXY

In most cases the fsck command will figure out what the filesystem is and run the appropriate filesystem checker.

Most offsite backup services are extremely secure. The key to safeguarding your information is the level of encryption offered by the backup provider. You should choose an encryption level of 128-bits or more for your maximum safety.

False. In face, there is virtually no level on security on those messages.

No

BitLocker Drive Encryption

IPSec with encapsulating encryption

This is fiercely dependent on your filesystem, but since the de facto standard filesystem for now is ext4, the typical maximum is 255 characters. It's not going to be practical to go over every filesystem Linux supports, so I'll just say read the manual.

The Linux Filesystem Hierarchy is used to help determine the file structure in the Linux Operating System. It defines the Directory structure and directory contents.

Each OS has some sort of filesystem. They also have some software to access this filesystem. This allows for a logical hierarchy for storing files.

People have developed many encryption algorithms.

One particular encryption algorithm is the Rijndael algorithm, usually called the AES or Advanced Encryption Standard.

That will depend on which type of encryption you wish to use, there are many different types depending on the level of security desired.

One of the coordinates that is used to address filesystem items when using Subversion is Path. Another coordinate used with this software is Revision.

A journaling filesystem provides increased reliability and faster recovery after a system crash because it keeps a record of changes before writing them to the main data storage. This helps prevent data corruption and reduces the risk of file system inconsistencies.

Encryption is converting plain text into cipher text . Yes, encryption can be cracked and then the text can be decrypted.

"Evaluating cryptography is difficult since without 'breaking' the encryption its hard to say whether one encryption is better or not. Pretty Good Encryption (PGP) is asymmetric, that is the encryption and decryption keys are different which may give it an edge on symmetric encryption."

Basic encryption (up to 256 bit encryption) software costs around $400 per year. Encryption softwares are not 100% foolproof.

If you mean full Hard disk encryption, right down to the FAT Table, then I would recommend using a third party program that supports such functions such as "Truecrypt".

NTFS for example supports file encryption and windows has "Bitlocker" which supports a type of drive encryption and file container encryption.

There are also hardware based methods which allows for OS transparent hard drive encryption that would prevent the drive from being read in another system without the hardware key.

File system is USUALLY not important. Since encryption at a hardware level bypasses the OS and is transparent to it.

what does the word skit stand for in encryption

Encryption

Linux is an operating system much like Microsoft Windows is. What mounting on this system mean is an additional filesystem was attached to the existing filesystem.

Mostly for performance - symmetric encryption is much much faster (order of magnitudes) than asymmetric encryption.

fsck /dev/sda1

Mostly for performance - symmetric encryption is much much faster (order of magnitudes) than asymmetric encryption.

ZFS is a filesystem developed and used by Sun Microsystems in their computers. It is not just a filesystem but also a logical volume manager. This means it is able to store the files more efficiently.

The ext4 filesystem is the default for Fedora16. It is possible to have different filesystems on different partitions on your system, so it is best to ask the system directly. To do this, use the command "df -T" (case matters - use "df --help" when in doubt). The df utility will tell you which filesystem exists for each partition of your system.

128 BIT-ENCRYPTION

strong encryption

WEP encryption is being used.

Some messages will require encryption.

Yes.

Public Key encryption (or asymmetric encryption) requires a pair of keys; a public and a private key for exchanging data in a secure manner.

PayPal provides a high level of fidelity and security for online transactions through encryption, fraud protection, and buyer and seller protection programs.

That depends on encryption you are using. In any case OS creates partitions and formats it (or specialized software). Next if you have software encryption, than special driver is installed which either encrypted files or whole disk by intercepting read and write operations called by OS. If you have hardware encryption, then your whole hard drive is encrypted on hardware level. It means that hardware has extra steps before writing or reading information on hard drive.

To format /dev/hda5 with ext3 file system.

As superuser: # mkfs.ext3 /dev/sda5

Important quote from a website: WARNING: Executing these commands will destroy all the data on your filesystem. So, try these commands only on a test system where you don't care about losing your data. Unquote.

HTTP does not provide any encryption services.

A: Symmetric

Cryptography or encryption are the two names of same technique and that is file encryption. File encryption is the best and most reliable and user friendly way to secure your data. Encryption software that are genuine and easy to use like Data Protecto and Folder Lock are ideal for encrypting your documents.

This is dependent on what filesystem is in use.

The de facto standard filesystem in Linux is ext4, which supports up to 255 characters on its filenames.

But if you are using something else it's better to look it up on Wikipedia.

df

Usually pronounced Fisk Disk, FSCK is a linux/unix software command used for file system checking. fsck [options] [filesystem] ... System administration command. Call the filesystem checker for the appropriate system type to check and repair unmounted filesystems. If a filesystem is consistent, the number of files, number of blocks used, and number of blocks free are reported. If a filesystem is inconsistent, fsck prompts before each correction is attempted. fsck's exit code can be interpreted as the sum of all conditions that apply: 1Errors were found and corrected. 2 Reboot suggested 4Errors were found but not corrected 8 fsckencountered an operational error 16 fsck was called incorrectly 128 A shared library error was detected -- Pass all subsequent options to filesystem-specific checker. All options that fsck doesn't recognize will also be passed -s Serial mode. Check one filesystem at a time -t fstype. Specify the filesystem type. Do not check filesystems of any other type -A Check all filesystems listed in /etc/fstab. The root filesystem is checked first -C Display completion (progress) bar -N Suppress normal execution; just display what would be done -PMeaningful only with -A: check root filesystem in parallel with other systems. This option is potentially dangerous -RMeaningful only with -A: check all filesystems listed in /etc/fstab except the root filesystem -T Suppress printing of title -V Verbose mode

If we want to transmit the most secret data, we can use encryption process and transmit the data to the receiver. this process is called as encryption.

AES is an acronym for Advanced Encryption Standard. AES is a variation of Rijndael. Is it used for encryption of electronic data and was established by NIST in 2001.
