Address Space Layout Randomization

Memory management is one of the main tasks of an Operating System, where the data of each process running in the system is kept. In this context, there exist several types of attacks that exploit memory-related vulnerabilities, forcing Operating Systems to feature memory protection techniques that make difficult to exploit them. One of these techniques is ASLR, whose function is to introduce randomness into the virtual address space of a process. The goal of this work was to measure, analyze and compare the behavior of ASLR on the 64-bit versions of Windows 10 and Ubuntu 18.04 LTS. The results have shown that the implementation of ASLR has improved significantly on these two Operating Systems compared to previous versions. However, there are aspects, such as partial correlations or a frequency distribution that is not always uniform, so it can still be improved.

CPU scheduling algorithms have a significant function in multiprogramming operating systems. When the CPU scheduling is effective a high rate of computation could be done correctly and also the system will maintain in a stable state. As well as, CPU scheduling algorithms are the main service in the operating systems that fulfill the maximum utilization of the CPU. This paper aims to compare the characteristics of the CPU scheduling algorithms towards which one is the best algorithm for gaining a higher CPU utilization. The comparison has been done between ten scheduling algorithms with presenting different parameters, such as performance, algorithm’s complexity, algorithm’s problem, average waiting times, algorithm’s advantages-disadvantages, allocation way, etc. The main purpose of the article is to analyze the CPU scheduler in such a way that suits the scheduling goals. However, knowing the algorithm type which is most suitable for a particular situation by showing its full properties.

Nowadays Mobile phones are becoming more popular in our daily lives. Mobile technology has a great effect on human life. Our daily tasks are dependent on mobile devices. Memory Management (MM), Security and Performance plays an important role in every handheld device specially in mobile phones, which are very much dependent on their operating system (OS). These embedded operating systems are on the driving seat when we talk about efficient and useful memory management and secure handling. Three popular OS in mobile phones are Android, Windows and iOS (iPhone OS). Each OS has its own way of managing the memory and provide it to certain number of applications. Android is an open software available for the people to modify as per their needs. But Windows and iOS operating systems didn’t allow their software as open source. Researchers have done a large amount of work using different mechanisms and decision makings to develop new ways to manage the memory of these OS’s. This work shows a comparative analysis of different memory management and security related techniques in above three operating systems. In this paper, we present the analysis of memory management and security in mobile phone operating systems with respect to apps, main memory, cache memory and virtual memory. Also, we compare the overall performance of these OS’s in terms of MM, security concerns. This study will help in finding better operating system in terms of efficient memory management and security.
