On the Internet Connectivity in Africa

November 18, 2015
Author(s)
Assane Gueye, Peter Mell, Desire Banse, Faical Y. Congo
This study measures and documents growth of Internet connectivity in Africa from 2010 to 2014 with a focus on inter-country relationships. We evaluate both intra-continent connectivity as well as connectivity to other continents. An initial analysis

Minimizing Attack Graph Data Structures

November 14, 2015
Author(s)
Peter Mell, Richard Harang
An attack graph is a data structure representing how an attacker can chain together multiple attacks to expand their influence within a network (often in an attempt to reach some set of goal states). Restricting attack graph size is vital for the execution

Defensive Resource Allocations with Security Chokepoints in IPv6 Networks

July 15, 2015
Author(s)
Assane Gueye, Peter M. Mell, Richard Harang, Richard J. La
Securely configured Internet Protocol version 6 networks can be made resistant to network scanning, forcing attackers to propagate following existing benign communication paths. We exploit this attacker limitation in a defensive approach in which

Measuring Limits on the Ability of Colluding Countries to Partition the Internet

June 30, 2015
Author(s)
Peter M. Mell, Richard Harang, Assane Gueye
We show that the strength of Internet-based network interconnectivity of countries is increasing over time. We then evaluate bounds on the extent to which a group of colluding countries can disrupt this connectivity. We evaluate the degree to which a group

Evasion-Resistant Network Scan Detection

May 9, 2015
Author(s)
Richard Harang, Peter Mell
Popular network scan detection algorithms operate through evaluating external sources for unusual connection patterns and traffic rates. Research has revealed evasive tactics that enable full circumvention of existing approaches (specifically the widely

Using Network Tainting to Bound the Scope of Network Ingress Attacks

July 1, 2014
Author(s)
Peter M. Mell, Richard Harang
This research describes a novel security metric, network taint, which is related to software taint analysis. We use it here to bound the possible malicious influence of a known compromised node through monitoring and evaluating network flows. The result is

What's Special About Cloud Security?

July 16, 2012
Author(s)
Peter M. Mell
While cloud security concerns have consistently ranked as one of the top challenges to cloud adoption, it is not clear what security issues are special with respect to cloud computing. To approach this question, we attempt to derive cloud security issues

The NIST Definition of Cloud Computing

September 28, 2011
Author(s)
Peter M. Mell, Timothy Grance
Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with
