Guidance for Secure Authorization of Mobile Applications in the Corporate Environment

March 19, 2015
Author(s)
Athanasios T. Karygiannis, Stephen Quirolgico, Larry Feldman, Gregory A. Witte
This bulletin provides an overview of NIST Special Publication (SP) 800-163, "Vetting the Security of Mobile Applications." The NIST SP helps organizations understand the process for vetting the security of mobile applications, plan for the implementation

The Multiplicative Complexity of Boolean Functions on Four and Five Variables

March 17, 2015
Author(s)
Meltem Sonmez Turan, Rene C. Peralta
A generic way to design lightweight cryptographic primitives is to construct simple rounds using small nonlinear components such as 4x4 S-boxes and use these iteratively (e.g., PRESENT and SPONGENT). In order to efficiently implement the primitive, optimal

Measuring the Resiliency of Cellular Base Station Deployments

March 11, 2015
Author(s)
David W. Griffith, Richard A. Rouil, Antonio Izquierdo Manzanares, Nada T. Golmie
The National Public Safety Telecommunications Council (NPSTC) has defined Resiliency as the ability of a network to withstand the loss of assets and to recover quickly from such losses. How to measure the resiliency of a base station deployment is an

Optimizing the Location Deployment of Dynamic Mobile Base Stations

February 19, 2015
Author(s)
Sulabh Bhattarai, Sixiao Wei, Stephen Rook, Wei Yu, David W. Griffith, Nada T. Golmie
There has been growing interest over the past few years in the US and around the world to build reliable, robust, and interoperable public safety broadband networks for emergency and disaster response. In this paper, we propose a low-cost, dynamic

Author(s)
Morris Chang, D. Richard Kuhn, Timothy Weil
How can IT professionals adapt to ever-changing security challenges quickly and without draining their organizations' resources? Articles in this issue highlight emerging trends and suggest ways to approach and address cybersecurity challenges. [guest

A Logic Based Network Forensics Model for Evidence Analysis

January 28, 2015
Author(s)
Changwei Liu, Anoop Singhal, Duminda Wijesekera
Many attackers tend to use sophisticated multi-stage and/or multi-host attack techniques and anti-forensic tools to cover their traces. Due to the limitations of current intrusion detection and network forensic analysis tools, reconstructing attack

Defensive code's impact on software performance

January 26, 2015
Author(s)
David W. Flater
Defensive code is instructions added to software for the purpose of hardening it against uncontrolled failures and security problems. It is often assumed that defensive code causes a significant reduction in software performance, which justifies its

Vetting the Security of Mobile Applications

January 26, 2015
Author(s)
Stephen Quirolgico, Jeffrey M. Voas, Tom T. Karygiannis, Christoph Michael, Karen Scarfone
The purpose of this document is to help organizations (1) understand the process for vetting the security of mobile applications, (2) plan for the implementation of an app vetting process, (3) develop app security requirements, (4) understand the types of
