The concept of Mandatory Access Controls (MAC) enforces a security policy on users. Linux Security Modules (LSM) provides for development of such frameworks. Lothlorien is an exploratory framework using LSM and the POSIX 1.e draft specifications' 1 Extended Attributes (EA) to implement MAC on Linux. Lothlorien makes use of system call hooks provided by LSM to place checks on the access to system resources. The entire system is divided logically into different zones where the resources and users of the systems are distributed depending on their security context similar to a real organisation. Along with the already available Discretionary Access Control (DAC) on Linux, Lothlorien intends to achieve TCSEC B1 level of security. A policy will define the rules of access. Separating all the entities of the system allows fine-grained access control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
