Reason being millions of people have fallen victim to identity theft associated with computer security and how the issue are related. There are three security technologies that are required to be researched in this paper referring to security and what organization. SELinux, chroot jail, and iptables are part of this research paper. In addition this paper must include how each technology changes the operating system to enforce security and if the security measure can be easily bypassed. Finally describe the types of threats each of the technologies is designed to eliminate.
First, SELinux which stands for Security-Enhanced Linux As part of its Information Assurance mission, the National Security Agency has long been involved with the computer security research community in investigating a wide range of computer security topics including operating system security. Recognizing the critical role of operating system security mechanisms in supporting security at higher levels, researchers from NSA's National Information Assurance Research Laboratory, been investigating an architecture that can provide the necessary security functionality in a manner that can meet the security needs of a wide range of computing environments.
End systems must be able to enforce the separation of information based on confidentiality and integrity requirements to provide system security. Operating system security mechanisms are the foundation for ensuring such separation. Unfortunately, existing mainstream operating systems lack the critical security feature required for enforcing separation: mandatory access control. As a consequence, application security mechanisms are vulnerable to tampering and bypass, and malicious or flawed applications can easily cause failures in system security.
