There are three types of journaling available in ext3 file system. Journal – Metadata and content are saved in the journal. Ordered – Only metadata is saved in the journal. Metadata are journaled only after writing the content to disk. This is the default. Writeback – Only metadata is saved in the journal. Metadata might be journaled either before or after the content is written to the
The original file system introduced with the Linux operating system is called the extended file system (or just ext for short). It provides a basic Unix- like file system for Linux, using virtual directories to handle physical devices, and storing data in fixed-length blocks on the physical devices.

Although there are already a lot of good security features built into Linux-based systems, one very important potential vulnerability can exist when local access is granted – – that is file permission based issues resulting from a user not assigning the correct permissions to files and directories.
In Windows, System and Program files are usually saved in C: drive. But, in Linux, you would find the system and program files in different directories. For example, the boot files are stored in the /boot directory, and program and software files can be found under /bin, device files in /dev. Below are important Linux Directories and a short description of what they contain.

What is the difference between Linux filesystems ext2

All files accessible in a Linux system are arranged in one big tree, the file hierarchy, rooted at /. These files can be spread out over several devices and they can be remote or local file system. Linux supports numerous file system types. For example it supports Ext2,. Ext3, NFS, FA16, FAT32, NTFS
When formatting partitions on a Linux PC, you’ll see a wide variety of file system options. These options don’t need to be overwhelming. If you’re not sure which Linux file system to use, there’s a simple answer. The Quick Answer: Use Ext4 if You’re Not Sure We’ll get into the weeds
There are many different types of file systems. Microsoft Windows administrators are familiar with filesystems like FAT16, FAT32, and NTFS. The comparable options on Linux are ext2, ext3, and Linux-swap. The differences between these filesystem types are beyond the scope of this book.
Ans : In general, Journaling file systems avoid file system corruption by maintaining a journal. The journal is a special file that logs the changes destined for the file system in a circular buffer .

$ file -sL /dev/sda1 /dev/sda1: writable, no read permission Method 4: View the /etc/fstab file. If a particular mount point is configured to be mounted automatically during system startup, you can identify its file system type by looking at the /etc/fstab file.
Three software layers are typically used to describe the Linux system: The file system is often a separate process, as are other parts of the kernel and various service daemons. The shell and other basic utilities layer: When you type in a command, it’s to the shell at the command-line interface (sometimes CLI). Some commands are built-in to the shell (e.g., cd for change directory) some


XFS is a high-performance file system which was designed by SGI for their IRIX platform. Since XFS was ported to the Linux kernel in 2001, XFS has remained a preferred choice for many enterprise systems especially with massive amount of data, due to its …
Filesystem Security 1 General Principles • Files and folders are managed by the operating system • Applications, including shells, access files through an API • Access control entry (ACE) – Allow/deny a certain type of access to a file/folder by user/group • Access control list (ACL) – Collection of ACEs for a file/folder • A file handle provides an opaque identifier for a file
By Emmett Dulaney . Part of Linux All-in-One For Dummies Cheat Sheet . To interact with the Linux file system, you must understand some basics: its key directories, some of the most commonly used commands, and the permissions you can assign to files.

In modern UNIX systems, such as Linux, the implementation of the le system is achieved by dynamically binding the implementations of le system calls to functions that are hard-coded in the particular le system that is mounted, a form of delayed binding as well.
This standard assumes that the operating system underlying an FHS-compliant file system supports the same basic security features found in most UNIX filesystems. It is possible to define two independent distinctions among files: shareable vs. unshareable and variable
When navigating the Linux file system you are sure to encounter different file types. The most used and obvious file types are regular files and directories.
