specify who can unlink, append only, move a file and so on. SELinux allows you to specify access to many resources other than files as well, such as network resources and interprocess communication. A Linux kernel integrating SELinux enforces mandatory access-control policies that confine user programs and system servers to the minimum amount of privilege they require to do their jobs. This reduces or eliminates the ability of these programs and daemons to cause harm when compromised. This confinement

Linux Security Technologies SELinux (Security Enhanced Linux) is a mandatory access control in the Linux kernel that was originally developed by NSA (National Security Agency) with direct contributions provided by Red Hat Enterprise Linux (RHEL) via the Fedora Project. In the day and age of identity theft and attempted sabotage from terrorists against our country, it should be very apparent why an organization like NSA had such an interest in heading up development of a more secure

IT302 Linux System Administration Research Assignment 1 SELinux or Security Enhanced Linux uses an architecture that separates enforcement from access policy decisions. With this architecture different types of policies can be implemented, including Role-Based Access Control (RBAC), Type Enforcement (TE), and Multi-Level Security (MLS). The module assigns security labels to each subject or object. It uses a security class to determine the kinds of relationship a pair of labels might have. The

Linux that can be implemented into a network. The three technologies that I will be discussing are SELinux, chroot jail, and iptables. SELinux was developed by the National Security Administration in an effort to incorporate a strong, flexible mandatory access control architecture into the major subsystems of the Linux kernel. The NSA recognized that operating system security is critical at higher levels. It provides a tool to enforce the separation of information based on the confidentiality

and advanced development of technologies needed to enable NSA to provide the solutions, products, and services to achieve Information Assurance for information infrastructures critical to U.S. National Security interests. The NSA implemented a Mandatory Access control within the Linux Kernel. This MAC is named Flask.2 There are three main policies that SELinux uses to apply MAC. There is the Targeted, where the MAC controls will only be used for a specific process or processes, there is the

, files or processes run by the user have the same access as the user. So if an attacker got hold of an admin account they would have complete control over any files or services that account runs or has access to. SELinux uses (MAC) mandatory access control. With this, services and files are controlled by policies saying what may or may not be done. MAC enforces these security policies that limit what users and programs can do. Security threats coming from user errors, attackers

monitor for a small business. 2. Top Ads is a small advertising company consisting of 12 computers that have internet access. All employees communicate using smart phones. Mandatory Access Controls should be used in this scenario because the employees primarily communicate using smart phones, which opens up a security risk. Mandatory Access Controls are a step up stronger than Discretionary Access Controls, but are still relatively simple to monitor for a small business. 3. NetSecIT is a multinational

How do you enable SELinux? In the /etc/selinux/config check to see of the SELinux is enabled in the status. If in the disabled status, enter command rpm -qa | grep selinux 3.
