Network Security Toolkit (NST) is a Linux-based Live DVD/USB Flash Drive that provides a set of free and open-source computer security and networking tools to perform routine security and networking diagnostic and monitoring tasks.
Linux Security Modules (LSM) is a framework allowing the Linux kernel to support, without bias, a variety of computer security models.LSM is licensed under the terms of the GNU General Public License and is a standard part of the Linux kernel since Linux 2.6.
On Linux and all Unix-like operating systems, the utilities ifconfig and the newer ip (from the iproute2-bundle) are used to configure IEEE 802.3 and IEEE 802.11 hardware. These utilities configure the kernel directly and the configuration is applied immediately.
Computer operating systems based on the Linux kernel are used in embedded systems such as consumer electronics (eg. set-top boxes, smart TVs and personal video recorders (PVRs)), in-vehicle infotainment (IVI), networking equipment (such as routers, switches, wireless access points (WAPs) or wireless routers), machine control, industrial automation, navigation equipment, spacecraft flight ...
This "snapshot" is used to build a database that is saved and may be stored on an external device for safekeeping. When the administrator wants to run an integrity test, the administrator places the previously built database in an accessible place and commands AIDE to compare the database against the real status of the system.
It appears as a block device, which can be used to back file systems, swap or as an LVM physical volume. Some Linux distributions support the use of dm-crypt on the root file system. These distributions use initrd to prompt the user to enter a passphrase at the console, or insert a smart card prior to the normal boot process. [3]
Tiger was originally developed by Douglas Lee Schales, Dave K. Hess, Khalid Warraich, and Dave R. Safford in 1992 at Texas A&M University. [1] [2] The tool was originally developed to provide a check of UNIX systems on the A&M campus that had to be accessed from off campus and, consequently, required clearance through the network security measures set in place.
Smack consists of three components: A kernel module that is implemented as a Linux Security Module.It works best with file systems that support extended attributes.; A startup script that ensures that device files have the correct Smack attributes and loads the Smack configuration.
