In computer security, executable-space protection marks memory regions as non-executable, such that an attempt to execute machine code in these regions will cause an exception. It makes use of hardware features such as the NX bit (no-execute bit), or in some cases software emulation of those features. However, technologies that emulate or ...
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.
The use of STIGs enables a methodology for securing protocols within networks, servers, computers, and logical designs to enhance overall security. These guides, when implemented, enhance security for software, hardware, physical and logical architectures to further reduce vulnerabilities.
Koozali SME server (also known as the SME Server, formerly e-smith server and gateway) is a Linux distribution based on Red Hat Enterprise Linux and can act a server-only or server and gateway. Core features include internet services such as HTTP , FTP or email servers and firewall .
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.
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.
Address space layout randomization (ASLR) is a computer security technique involved in preventing exploitation of memory corruption vulnerabilities. [1] In order to prevent an attacker from reliably redirecting code execution to, for example, a particular exploited function in memory, ASLR randomly arranges the address space positions of key data areas of a process, including the base of the ...
Security-Enhanced Linux (SELinux) is a Linux kernel security module that provides a mechanism for supporting access control security policies, including mandatory access controls (MAC). SELinux is a set of kernel modifications and user-space tools that have been added to various Linux distributions .
