Since its release to the public in 1991, the Linux operating system has become one of the most widely used operating systems in the world. This is largely because of the security features. The most popular of these three technologies are SELinux, chroot jail and iptables. We are going to break down the advantages and benefits of each of these features. The United States National Security Agency (NSA), the original developer of SELinux released the first version of this feature in December of 2000

Introduction Today we live in a world where technology is the way to go. Even in this century there are people that are still clueless on the operating system. It is different, exciting when a new and advance system comes out. But some of us are so confused when it comes to the basics of new technology. Operating systems are programs which manages the computer’s hardware. The systems provide a basic for the applications programs between the computer user and its hardware. When looking

research partners from NAI Labs, Secure Computing Corporation (SCC), and the MITRE Corporation. Many other contributions have followed since the initial release.(NSA-National Security Agency, 2009) Researchers in the National Information Assurance Research Laboratory of NSA worked with Secure Computing Corporation (SCC) to develop a strong, flexible mandatory access control architecture based on a mechanism first developed for the LOCK system called Type Enforcement. The NSA and SCC then worked with the

-The purpose of information system security is to develop security controls to prevent security weaknesses from being exploited by threat agents. -A threat agent is an entity who is responsible for or who materially contributes to the loss or theft of data. Threat agents may be internal or external to an organization. -Unintentional agents—Unintentional threat agents are employees, contractors, or other insiders who have no motivation to jeopardize information, but who are untrained or negligent

started by the NSA (National Security Agency) and had additions from several other groups such as Network Associates, Treys, and others. Released as a set of patches in the beginning SELinux has molded its way into the Linux kernel as of kernel release 2.6. This was needed since in the early stages of SELinux it provided its own security framework which caused issues with GNU/Linux because it put Linux into a single access-control architecture. To correct this situation the Linux kernel inherited

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 (IPC). SELinux is an implementation of mandatory access controls (MAC) on Linux. Mandatory access controls allow an administrator of a system to define how applications and users can access different resources such as files, devices, networks and inter-process communication. SELinux can help protect you from bugs

allow the current user to access the file(s) or application at the highest permission allow, the owner of the file, or user. SELinux introduced two new ways to allow permissions to be determined by the client computer. The first of these is MAC, Mandatory Access Control. This new protocol introduce the principle of least privilege, which simply allows programs to use what resources they need to do the task at hand, and nothing else. An example from an article I found online: "if you have a program
