The LSM design is described in the paper Linux Security Modules: General Security Support for the Linux Kernel [1] presented at USENIX Security 2002. [2] At the same conference was the paper Using CQUAL for Static Analysis of Authorization Hook Placement [ 3 ] which studied automatic static analysis of the kernel code to verify that all of the ...
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 ).
Network access control (NAC) is an approach to computer security that attempts to unify endpoint security technology (such as antivirus, host intrusion prevention, and vulnerability assessment), user or system authentication and network security enforcement. [1] [2]
Endpoint security management is a software approach that helps to identify and manage the users' computer and data access over a corporate network. [3] This allows the network administrator to restrict the use of sensitive data as well as certain website access to specific users, to maintain, and comply with the organization's policies and standards.
A core security feature in these systems is the file system permissions. All files in a typical Unix filesystem have permissions set enabling different access to a file. Unix permissions permit different users access to a file with different privilege (e.g., reading, writing, execution).
This is a list of operating systems specifically focused on security.Similar concepts include security-evaluated operating systems that have achieved certification from an auditing organization, and trusted operating systems that provide sufficient support for multilevel security and evidence of correctness to meet a particular set of requirements.
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.
Linux portal; Linux (and other Unix-like systems) have a multi-tier security that permits user root any system-wide changes. Regular users can be limited: where they can save files, what hardware they can access, their memory usage, applications, disk usage (), and the range of priority settings they can apply, can all be specified to provide sufficient freedoms.
