Using VProbes for intrusion detection
Many current intrusion detection systems (IDSes) are vulnerable to intruders because they are running under the same operating system (OS) as a potential attacker. Since an attacker will often be attempting to co-opt the OS, this leaves the IDS vulnerable to subversion by the attacker. While some …

Operating System Identification by IPv6 Communication using Machine Learning Ensembles
<p>Operating system (OS) identification tools, sometimes called fingerprinting tools, are essential for the reconnaissance phase of penetration testing. While OS identification is traditionally performed by passive or active tools that use fingerprint databases, very little work has focused on …

Anomaly Detection in Database Operating System
Database Operating System (DBOS) is a new operating system (OS) framework that replaces the traditional file-based system with a high-performance database management system (DBMS). This design choice addresses the needs of a rapidly evolving software and hardware landscape that cannot be met by a …

Symmetric MultiProcessing for the Pintos Instructional Operating System
… these additional units requires support from the operating system (OS). Indeed, most modern operating systems do have the capability of recognizing and utilizing multiprocessor hardware. Pintos is an instructional operating system used by many institutions to teach important operating systems …

Artificial Intelligence for Android Stealth-Attack Detection: A Digital Forensics Approach
Android is the most popular Operating System (OS) for mobile devices worldwide due to its low cost and open-source platform. Various apps for different services have been developed, but the incorrect management of specific data structures and code sections can lead to vulnerabilities, allowing …

Message passing in a factored OS
The fos project aims to build a next generation operating system (OS) for clouds and manycores with hundreds or thousands of cores. The key design tenant of fos is to break operating system services into collections of distributed system processes that communicate with message passing rather than …

Generic Multisensor Integration Strategy and Innovative Error Analysis for Integrated Navigation
A modern multisensor integrated navigation system applied in most of civilian applications typically consists of GNSS (Global Navigation Satellite System) receivers, IMUs (Inertial Measurement Unit), and/or other sensors, e.g., odometers and cameras. With the increasing availabilities of low-cost …

Rethinking computer architecture and operating system abstractions for good & evil
Computing systems are undergoing a radical shift, propelled by stern security requirements and an unprecedented growth in data and users. This change has proven to be abstraction breaking. Current hardware and Operating System (OS) abstractions were built at a time when we had minimal security …

Protecting enclaves from side-channel attacks through physical isolation
… increasingly crucial role in our lives. Digital systems control our calendars, how we gain access to our devices and even the vehicles we use for transportation. It is therefore no surprise that security solutions like trusted execution environments (TEEs) have been introduced in many systems …

Energy Efficient Real-time Operating Systems on Chip
… capacity. The power consumption of actuation systems used in micro-robots is within the same magnitude of the power consumption of the compute system. Thus, the remaining factor for enabling these micro-robots is associated with the design of energy-efficient compute systems. Energy usage of …

Generalizing robot application development: operating system and framework abstractions
As general-purpose robots begin to find their way into the household and workplace, there will be a demand for software to run on these robots. We foresee the proliferation of robot apps that use a common set of abstractions to allow them to function on a variety of hardware platforms. In this …

Operating system support for warehouse-scale computing
… increasingly backed by large-scale data centres. Systems software in these data centre environments, however, faces substantial challenges: the lack of uniform resource abstractions makes sharing and resource management inefficient, infrastructure software lacks end-to-end access control …

Single System Image in a Linux-based Replicated Operating System Kernel
… breaking the power wall. However, existing system software is able to cope with homogeneous architectures, but it was not designed to run on heterogeneous architectures, therefore, new system software designs are necessary. One innovative design is the multikernel OS deployed by the …

Thread Scheduling For Chip Multiprocessors
… performance. For example, software and the operating system assume off-core resources increase in tandem with numbers of cores, which is often not the case. The result is poor performance because scheduling decisions fail to properly account for this non-uniform substrate. We investigate how …

On Improving the Security of Virtualized Systems through Unikernelized Driver Domain and Virtual Machine Monitor Compartmentalization and Specialization
… backbone of cloud infrastructures. Its core subsystems include hypervisors and virtual machine monitors (VMMs). They ensure the isolation and security of co-existent virtual machines (VMs) running on the same physical machine. Traditionally, driver domains -- isolated VMs in a hypervisor such as …

A High-Availability Architecture for the Dynamic Domain Name System
The Domain Name System (DNS) provides a mapping between host names and Internet Protocol (IP) addresses. Hosts that are configured using the Dynamic Host Configuration Protocol (DHCP) can have their assigned IP addresses updated in a Dynamic DNS (DDNS). DNS and DDNS are critical components of the …
