A Platform Independent Risk Analysis for Mobile Ad hoc Networks
Antonio Martin (SCA Technica, USA, tmemail@gmail.com)
Boston University Conference on Information Assurance and Cyber Security, Dec 2006
ABSTRACT:
Mobile Ad Hoc Networking (MANET) adds a layer on top of wireless communication to
assist in multi-hop routing of packets across a network topology. Extensive work has
been performed in the field of secure MANET and ad hoc routing with examples found in
Secure AODV (SAODV) and Authenticated Routing for Ad hoc Networks (ARAN) [1].
By contrast, in openly published literature, little has been written about threats and risks
for MANET networks; a key needed in developing any protection profile and
architecture. Without a threat / risk analysis, current MANET security works’
effectiveness are difficult to assess. This paper provides a tutorial of MANET specific
attacks and a platform independent, risk analysis by identifying assets, vulnerabilities and
threats, usable for future MANET deployments and security work.

Viral Threats – An Examination of Current and Evolving Technologies
Antonio Martin (SCA Technica, USA, tmemail@gmail.com)
Boston University Conference on Information Assurance and Cyber Security, Dec 2006
ABSTRACT:
Virus/Malware/Worms and other such infections are on the increase, technological security advancements
are falling behind as zero day exploits become prevalent and system infections become impossible to
detect. Security industry dollars are primarily focused on reactive and not proactive solutions; patches and
signature definitions are days, if not weeks behind active exploits. Attacks have been confined, limited to
individual infected machines tied into "bot nets" numbering into the thousands, utilized primary by
individuals for financial gains. This playground is evolving as state sponsored activities are on the rise as
seen in the attacks on multiple US government facilities and agencies. Further consideration and
awareness must be made for what trends might evolve, not only within the next month or year, but a
broader horizon of five plus years, so defensive technology development can begin before problems arise.
This paper will attempt to consider the current, near term and future evolution of computational attacks
and map these to possible deployment timeframes and developmental complexity and examine possible
technologies needed to help combat pending threats. Furthermore, several scenarios will be illustrated,
outlining how some of these current and future viral technologies can be leveraged into wide scale
attacks. The paper's purpose is to facilitate discussions about future computational infections, the
technology they will employ and new ideas for future development.
