What is Grsecurity Ubuntu?

What is grsecurity? Grsecurity^® is an extensive security enhancement to the Linux kernel that defends against a wide range of security threats through intelligent access control, memory corruption-based exploit prevention, and a host of other system hardening that generally require no configuration.

What is SELinux used for?

Security-Enhanced Linux (SELinux) is a security architecture for Linux® systems that allows administrators to have more control over who can access the system. It was originally developed by the United States National Security Agency (NSA) as a series of patches to the Linux kernel using Linux Security Modules (LSM).

Are Unikernels more secure?

The most compelling reason to use Unikernels is their potential for security which takes advantage of their reduced attack surface, isolation and, depending on the distribution, a robust set of security features [14].

What type of Linux is Wifislax?

Wifislax is a Slackware-based live CD containing a variety of security and forensics tools. The distribution's main claim to fame is the integration of various unofficial network drivers into the Linux kernel, thus providing out-of-the-box support for a large number of wired and wireless network cards.

What is a kennel in Linux?

The Linux® kernel is the main component of a Linux operating system (OS) and is the core interface between a computer's hardware and its processes. It communicates between the 2, managing resources as efficiently as possible.

What is Evdev in Linux?

evdev (short for 'event device') is a generic input event interface in the Linux kernel and FreeBSD. It generalizes raw input events from device drivers and makes them available through character devices in the /dev/input/ directory.

What is use of Lsmod in Linux?

The lsmod command is used to display the status of modules in the Linux kernel. It results in a list of loaded modules. lsmod is a trivial program which nicely formats the contents of the /proc/modules , showing what kernel modules are currently loaded.

Where is KConfig Linux?

Kconfig-related tools and source code reside mainly under scripts/kconfig/ in the kernel source.

Why do we use config file?

In computing, configuration files (commonly known simply as config files) are files used to configure the parameters and initial settings for some computer programs. They are used for user applications, server processes and operating system settings.
