Delving into the Linux filesystem
The Linux operating system uses the EXT, which has many features, as well as providing speed and performance for the operating system. There are a few versions of EXT and, as a cybersecurity professional, it's beneficial to understand the characteristics of each one. Let's have a look at the different versions here:
- EXT2: This version was originally the default filesystem for any distribution of the Linux operating system. Today, it still is the preferred choice for some flash-based storage devices, even though it does not support journaling.
Important note
Journaling is a feature that improves performance and reduces the number of times data is written to an HDD or a SDD. By reducing the number of times data is written to a drive, it increases the lifespan of the drive itself.
- EXT3: EXT3 supports journaling, which is designed to provide improved performance. With journaling added to EXT3, this reduces the risk of a filesystem...
