Resilient Interdomain Traffic Exchange: BGP Security and DDos Mitigation

December 17, 2019
Author(s)
Kotikalapudi Sriram, Douglas C. Montgomery
In recent years, numerous routing control plane anomalies, such as Border Gateway Protocol (BGP) prefix hijacking and route leaks, have resulted in denial-of-service (DoS), unwanted data traffic detours, and performance degradation. Large-scale distributed

BotSifter: A SDN-based Online Bot Detection Framework in Data Centers

June 9, 2019
Author(s)
An Wang, Zili Zha, Yang Guo, Douglas Montgomery, Songqing Chen
Botnets continue to be one of the most severe security threats plaguing the Internet. Recent years have witnessed the emergence of cloud-hosted botnets along with the increasing popularity of cloud platforms, which attracted not only various applications

Soft MUD: Implementing Manufacturer Usage Descriptions on OpenFlow SDN Switches

March 24, 2019
Author(s)
Mudumbai Ranganathan, Douglas Montgomery, Omar Ilias El Mimouni
Manufacturer Usage Descriptions are generalized network Access Control Lists (ACL) that allow manufacturers to declare intended communication patterns for devices (Things). MUD-enabled Things are restricted to only communicate in the manner intended by the

A General Methodology for Deriving Network Propagation Models of Computer Worms

February 14, 2019
Author(s)
Shuvo Bardhan, Douglas C. Montgomery, James J. Filliben, Nathanael A. Heckert
Externally-launched computer worms which maliciously propagate within networks are one of the most serious and dangerous security threats facing the commercial, political, military, and research community today. With an eye to the ultimate goal of

Instrumenting Open vSwitch with Monitoring Capabalities: Designs and Challenges

March 28, 2018
Author(s)
Zili Zha, An Wang, Yang Guo, Douglas C. Montgomery, Songqing Chen
The recent advances on Software-Defined Networking (SDN) have made flexible and programmable network measurement possible. A promising trend is to conduct network traffic measurement on the widely deployed Open vSwitches (OVS) in data centers. However

vPROM: vSwitch Enhanced Programmable Measurement in SDN

October 10, 2017
Author(s)
An Wang, Yang Guo, Songqing Chen, Fang Hao, T.V. Lakshman, Douglas C. Montgomery, Kotikalapudi Sriram
Network programmability is a salient feature of Software Defined Networking (SDN), which allows users to program network applications with the perception that the underlying network is a single device. While still at an early stage of development, SDN

A Comparative Analysis of BGP Anomaly Detection and Robustness Algorithms

January 28, 2009
Author(s)
Kotikalapudi Sriram, Oliver Borchert, Patrick Gleichmann, Douglas C. Montgomery
We present an evaluation methodology for comparison of existing and proposed new algorithms for Border Gateway Protocol (BGP) anomaly detection and robustness. A variety of algorithms and alert tools have been proposed and/or prototyped recently. They

Architectural Considerations for Mapping Distribution Protocols

August 1, 2008
Author(s)
Kotikalapudi Sriram, Young-Tak Kim, Douglas C. Montgomery
In this paper, we present a discussion of some architectural ideas pertaining to the mapping distribution protocol. The efficiency of this protocol in terms of response time and the volume of traffic load it generates are important considerations. We

A Profile for IPv6 in the U.S. Government - Version 1.0

July 1, 2008
Author(s)
Douglas C. Montgomery, J. S. Nightingale, Sheila E. Frankel, Mark E. Carson
This publication seeks to assist Federal agencies in formulating plans for the acquisition of IPv6 technologies. To achieve this, we define a standards profile for IPv6 in the USG that is intended to be applicable to all future uses of IPv6 in non-

Border Gateway Protocol Security

July 17, 2007
Author(s)
D. Richard Kuhn, Kotikalapudi Sriram, Douglas Montgomery
This document introduces the Border Gateway Protocol (BGP), explains its importance to the internet, and provides a set of best practices that can help in protecting BGP. Best practices described here are intended to be implementable on nearly all
