Januar 2021 Dekan: Prof. Dr. Thomas Schuster Prüfungsausschuss: Vorsitzender: Prof. Dr. Thorsten Herfet Berichterstattende: Prof. Dr. Michael Backes Prof. Dr. Andreas Zeller Akademischer Mitarbeiter: Dr. Michael Schilling Zusammenfassung Android ist nicht nur das beliebteste Betriebssystem für mobile Endgeräte, sondern auch ein ein attraktives Ziel für Angreifer. Um diesen zu begegnen, nutzt Androids Sicher- heitskonzept App-Isolation und Zugangskontrolle zu kritischen Systemressourcen. Nutzer haben dabei aber nur wenige Optionen, App-Berechtigungen gemäß ihrer Bedürfnisse einzuschränken, sondern die Entwickler entscheiden über zu gewährende Berechtigungen. Androids Sicherheitsmodell kann zudem nicht durch Dritte angepasst werden, so dass Nutzer zum Schutz ihrer Privatsphäre auf die Gerätehersteller angewiesen sind. Diese Dissertation präsentiert einen Ansatz, Android mit umfassenden Privatsphäreeinstellun- gen nachzurüsten. Dabei geht es konkret um Techniken, die ohne Modifikationen des Betriebssystems oder Zugriff auf Root-Rechte auf regulären Android-Geräten eingesetzt werden können. Der erste Teil dieser Arbeit etabliert Techniken zur Durchsetzung von Sicherheitsrichtlinien

    How to XDP (with Snabb) Max Rottenkolber <[email protected]> Tuesday, 21 January 2020 Table of Contents Intro 1 Creating an XDP socket 2 Mapping the descriptor rings 4 Binding an XDP socket to an interface 7 Forwarding packets from a queue to an XDP socket 8 Creating a BPF map . 9 Assembling a BPF program . 9 Attaching a BPF program to an interface . 12 Packet I/O 14 Deallocating the XDP socket 18 Intro Networking in userspace is becoming mainstream. Recent Linux kernels ship with a feature called eXpress Data Path (XDP) that intends to con- solidate kernel-bypass packet processing applications with the kernel’s networking stack. XDP provides a new kind of network socket that al- lows userspace applications to do almost direct I/O with network device drivers while maintaining integration with the kernel’s native network stack. To Snabb XDP looks like just another network I/O device. In fact the XDP ABI/API is so similar to a typical hardware interfaces that it feels a bit like driving a NIC, and not by accident. I think it is fair to describe XDP as a generic interface to Linux network drivers that also 1 has a virtual backend it integrates with: the Linux network stack. In that sense, XDP can be seen as a more hardware centric sibling of AF_PACKET. I can think of two reasons why XDP might be interesting for Snabb users: • While the Snabb community prefers NICs with open hardware interface specifications there are a lot of networking devices out there that lack open specifications.

  • Improving Networking
    IMPERIAL COLLEGE LONDON FINALYEARPROJECT JUNE 14, 2010 Improving Networking by moving the network stack to userspace Author: Matthew WHITWORTH Supervisor: Dr. Naranker DULAY 2 Abstract In our modern, networked world the software, protocols and algorithms involved in communication are among some of the most critical parts of an operating system. The core communication software in most modern systems is the network stack, but its basic monolithic design and functioning has remained unchanged for decades. Here we present an adaptable user-space network stack, as an addition to my operating system Whitix. The ideas and concepts presented in this report, however, are applicable to any mainstream operating system. We show how re-imagining the whole architecture of networking in a modern operating system offers numerous benefits for stack-application interactivity, protocol extensibility, and improvements in network throughput and latency. 3 4 Acknowledgements I would like to thank Naranker Dulay for supervising me during the course of this project. His time spent offering constructive feedback about the progress of the project is very much appreciated. I would also like to thank my family and friends for their support, and also anybody who has contributed to Whitix in the past or offered encouragement with the project. 5 6 Contents 1 Introduction 11 1.1 Motivation.................................... 11 1.1.1 Adaptability and interactivity.................... 11 1.1.2 Multiprocessor systems and locking................ 12 1.1.3 Cache performance.......................... 14 1.2 Whitix....................................... 14 1.3 Outline...................................... 15 2 Hardware and the LDL 17 2.1 Architectural overview............................. 17 2.2 Network drivers................................. 18 2.2.1 Driver and device setup.......................

  • Towards Access Control for Isolated Applications
    Towards Access Control for Isolated Applications Kirill Belyaev and Indrakshi Ray Computer Science Department, Colorado State University, Fort Collins, U.S.A Keywords: Access Control, Service and Systems Design, Inter-application Communication. Abstract: With the advancements in contemporary multi-core CPU architectures, it is now possible for a server operating system (OS), such as Linux, to handle a large number of concurrent application services on a single server instance. Individual application components of such services may run in different isolated runtime environ- ments, such as chrooted jails or application containers, and may need access to system resources and the ability to collaborate and coordinate with each other in a regulated and secure manner. We propose an access control framework for policy formulation, management, and enforcement that allows access to OS resources and also permits controlled collaboration and coordination for service components running in disjoint containerized environments under a single Linux OS server instance. The framework consists of two models and the policy formulation is based on the concept of policy classes for ease of administration and enforcement. The policy classes are managed and enforced through a Linux Policy Machine (LPM) that acts as the centralized reference monitor and provides a uniform interface for accessing system resources and requesting application data and control objects. We present the details of our framework and also discuss the preliminary implementation to demonstrate the feasibility of our approach. 1 INTRODUCTION plications for controlling access to OS resources, for regulating the access requests to the application data The advancements in contemporary multi-core CPU and control objects used for inter-application commu- architectures have greatly improved the ability of nication between service components.

For purposes of calculating and applying an "annual basis," it means a consecutive 12-month period, beginning upon CenturyTel's written notice that an audit will be performed for the State. 2 .20 .7.1 [Intentionally omitted] 2 .20 .7.2 Unless otherwise agreed by the Parties (including at the time of the audit), the independent auditor shall perform its evaluation in accordance with the standards established by the American Institute for Certified Public Accountants (AICPA), which will require the auditor to perform an "examination engagement" and issue an opinion that includes the auditor's determination regarding Socket's compliance with the qualifying service Eligibility Requirements criteria. The independent auditor's report will conclude whether Socket complied in all material respects with this Section 2.20. 2 .20 .7.3 Consistent with standard auditing practices, such audits require compliance testing designed by the independent auditor, which typically include an examination of a sample selected in accordance with the independent auditor's judgment. 2.20 .7.4 Should the independent auditor's report conclude that Socket failed to comply in all material respects with Section 2.20, Socket must true-up any difference in payments paid to CenturyTel and the rates and charges Socket would have owed CenturyTel beginning from the date that the non-compliant circuit was established as a UNE/UNE combination, in whole or in part (notwithstanding any other provision hereof), but no earlier than the date on which this Section 2.20 of this Article is effective .
