On a Linux system, the boot partition (/boot) may be encrypted if the bootloader itself supports LUKS (e.g. GRUB). This is undertaken to prevent tampering with the Linux kernel. However, the first stage bootloader or an EFI system partition cannot be encrypted (see Full disk encryption#The boot key problem). [14]
KDE Wallet Manager (KWallet) is free and open-source password management software written in C++ for UNIX-style operating systems. KDE Wallet Manager runs on a Linux-based OS and Its main feature is storing encrypted passwords in KDE Wallets. [2]
In addition to the BSDs, a few Linux distributions have implemented similar infrastructure, including Gentoo's Portage, Arch's Arch Build System (ABS), CRUX's Ports and Void Linux's Templates. The main advantage of the ports system when compared with a binary distribution model is that the installation can be tuned and optimized according to ...
Pacman, a package manager written specifically for Arch Linux, is used to install, remove and update software packages. [13] An alternative is the Arch User Repository (AUR), which is the community-driven repository for Arch Linux; AUR packages can be downloaded and built, or installed through an AUR 'helper'.
The cryptsetup command-line interface, by default, does not write any headers to the encrypted volume, and hence only provides the bare essentials: encryption settings have to be provided every time the disk is mounted (although usually employed with automated scripts), and only one key can be used per volume; the symmetric encryption key is directly derived from the supplied passphrase.
The device mapper is a framework provided by the Linux kernel for mapping physical block devices onto higher-level virtual block devices.It forms the foundation of the logical volume manager (LVM), software RAIDs and dm-crypt disk encryption, and offers additional features such as file system snapshots.
EncFS is a Free FUSE-based cryptographic filesystem.It transparently encrypts files, using an arbitrary directory as storage for the encrypted files. [4] [5]Two directories are involved in mounting an EncFS filesystem: the source directory, and the mountpoint.
syslog-ng is a free and open-source implementation of the syslog protocol for Unix and Unix-like systems. It extends the original syslogd model with content-based filtering, rich filtering capabilities, flexible configuration options and adds important features to syslog, like using TCP for transport.
