Safe Operating

Linux is a comparatively safe operating system. This paper makes a research about the security policy for Linux, analyzing the principle and design idea of its identification and authentication mechanism, access control mechanism, Capability mechanism and security audit system. In this paper, the disadvantages of Linux system are pointed out and an improvement program is indicated so that the security performance of this system can be more effectively strengthened.

Access Control Mechanism

This proposed literature survey provides basic data regarding the first step of risk identification and analysis to achieve a secured infrastructure. The demand and risk are two parts of the same coin. The demand is directly proportional to the risk, but preventive control is inversely proportional to risk. The necessity of preventive control in any organization has increased because of the changes in logic, structure, and the type of technology applied to services that generate risks. Finally, the business increases along with technology, which creates risks and spreads over its infrastructure. We have to focus on protecting, detecting, correcting, verifying and validating the Unix file system. This survey article proposes and resolves the Unix file system by applying a hardening, re-configuration and access control mechanism up to the highest level of preventive control.

Access Control Mechanism

It is important to notice that the access control mechanism has been widely applied in various areas, such as on-line video systems, wireless network, and electronic documents. We propose an access control mechanism which is constructed based on two mathematical fundamentals: Lagrange interpolation and ElGamal algorithm. We conduct performance analysis to compare the efficiency of our proposed scheme with that of several related published schemes in both key generation phase and key derivation phase. Our new scheme is proven to be more efficient. It is shown, as expected, a more efficient scheme provides relatively less security and a more secure scheme is relatively less efficient for private keys of the same size.
