Countering kernel rootkits with lightweight hook protection. This paper presents a technique to prevent hook-indirection in Linux kernel by different attacks that redirect the control flow. It assumes that most of the kernel hooks are not dynamic and aren’t changed after initialization. Since modern hardware doesn’t provide memory.
Linux and Windows family operating systems that are based on NT are most typical operating systems at the moment, but Linux focus on executing efficiency while Windows family pay more attention to convenient use. As to kernel architecture, Linux is a monolithic kernel operating system, and the whole kernel is very compact. Maintaining for this.Linux: The Creation Of The Linux Operating System - Linux is an operating system developed by Linus Benedicts Torvalds. The operation system is the key of communication between the software and the hardware. Linux is a free and open-source software1 built around the Linux kernel. The first event leading to its creation is the conception of the.Much research has gone into mitigating the effects of kernel vulnerabilities, but kernel vulnerabilities, and more importantly, kernel exploits, are still prevalent in Linux. This paper investigates where the research community may want to focus its attention, by analyzing past Linux kernel vulnerabilities, categorizing them, evaluating what.
The paper summarizes our preliminary investigations into the evolution of the best known open source system: the Linux operating system kernel. Because Linux is large (over two million lines of.
From the Book: PREFACE This book grew out of the simple desire to describe exactly how Linux works on an IA-64 machine. By realizing that desire, we hope not only to shine a light on the inner workings of Linux, but also to share some of the excitement and the creative processes that are involved in solving the many technical challenges that arise when designing an operating system for a.
Linux is the dominant OS across nearly every imaginable typeofcomputersystemtoday.Linuxisrunninginbillionsof people’s pockets, in millions of our homes, in cars, in planes, in spaceships (15), embedded throughout our networks, and on each of the top 500 supercomputers (2). To accomplish this, the Linux kernel has been continuously expanded to.
However, it is particularly challenging for kernel developers to correctly apply new permission checks and to scalably verify the soundness of existing checks due to the large codebase and complexity of the kernel. In fact, Linux kernel contains millions of lines of code with hundreds of permission checks, and even worse its complexity is fast.
The Linux kernel, since its inception in 1991, has captured the interest of many thousands of developers and millions of users. It recently celebrated its 16th anniversary, includes many millions.
Writing a research paper is a huge task in itself. When you think about how easy it is for other people to copy or plagiarize the paper you worked hard on, this should encourage you to learn how to protect your research papers and other documents on your Linux computer.
Research and realization of the mechanism of embedded linux kernel semaphore Abstract: Linux kernel semaphore mechanism is an effective means of synchronizing tasks which compete against each other to enter the same kernel critical section. However, the problem of priority inversion in Linux kernel semaphore is still unsolved. It is very important to solve the problem of priority inversion by.

In 1991, he was a second year computer science student in Finland. He sought after an operating system that was similar to the UNIX system, but both UNIX and the hardware it ran on were excessively.
Custom Linux Kernel for Raspberry Pi Using Ubuntu 12.04 Host free download Abstract: In this paper, it is discussed that the Linux kernel customization for ARM11 platform based Raspberry Pi. In this customization of kernel using different tool chains is done. It will show how to configure and cross compile Linux kernel for the Raspberry Pi on.
However, we observe that applying hybrid fuzzing to kernel testing is challenging because the following unique characteristics of the kernel make a naive adoption of hybrid fuzzing inefficient: 1) having many implicit control transfers determined by syscall arguments, 2) controlling and matching internal system state via system calls, and 3.
Abstract. In this paper, we propose a way to implement the cross-platform system-level virtual layer in Linux kernel to achieve a higher performance, because, the virtual layer can be supported directly by the operating system and can directly interact with the real hardware without the performance cost of virtual device and user-space.

Flexera's Secunia Research team is comprised of a number of security specialists that discover critical vulnerabilities in products from numerous vendors.
The Security-enhanced Linux kernel enforces mandatory access control policies that confine user programs and system servers to the minimum amount of privilege they require to do their jobs. When confined in this way, the ability of these user programs and system daemons to cause harm when compromised (via buffer overflows or misconfigurations.
