\frametitle{D4 - Problem statement}
|
||||
\begin{itemize}
|
||||
\item CSIRTs (or private organisations) build their {\bf own honeypot, honeynet or blackhole monitoring network}
|
||||
\item Designing, managing and operating such infrastructure is a tedious and resource intensive task
|
||||
\item {\bf Automatic sharing} between monitoring networks from different organisations is missing
|
||||
\item Sensors and processing are often seen as blackbox or difficult to audit
|
||||
|

\frametitle{D4 - Objective}
|
||||
\begin{itemize}
|
||||
\item Based on our experience with
|
||||
MISP\footnote{\url{https://github.com/MISP/MISP}} where sharing
|
||||
played an important role, we transpose the model in D4 project
|
||||
\item Keeping the protocol and code base {\bf simple and minimal}
|
||||
\item Allowing every organisation to {\bf control and audit their own sensor network}
|
||||
\item Extending D4 or {\bf encapsulating legacy monitoring protocols} must be as simple as possible
|
||||
\item Ensuring that the sensor server has {\bf no control on the sensor} (unidirectional streaming)
|
||||
\item Don't force users to use dedicated sensors and allow {\bf flexibility of sensor support} (software, hardware, virtual)
|
||||

\item D4 encapsulation protocol version 1 published - {\bf 1st December 2018}
|

\item v0.1 release of the D4 core\footnote{\url{https://www.github.com/D4-project/d4-core}} including a server and simple D4 C client - {\bf 21st January 2019}
|

\item First version of a golang D4

IoT devices {\bf are often the weakest devices} on a network:

\begin{itemize}

\item Usually the result of cheap engineering,
|

\item sloppy patching cycles,
|

\item sometimes forgotten--not monitored,

\item few hardening features enabled,
|

\frametitle{Snake Oil Crypto - RSA on IoT }
|
||||
Researchers have shown that several devices generated their public
|
||||
keys at boot time without enough entropy\footnote{Bernstein, Heninger, and Lange: \url{http://facthacks.cr.yp.to/}}:
|
||||
|
||||
\begin{lstlisting}[frame=single, language=python]
|
||||
prng.seed(seed)
|
||||
p = prng.generate_random_prime()
|
||||
// prng.add_entropy()
|
||||
q = prng.generate_random_prime()
|
||||
n = p*q
|
||||
\end{lstlisting}
|
||||
|
||||
Given n=pq and n' = pq' it is trivial to recover the shared p by computing their
|
||||
Greatest Common Divisor (GCD), and therefore both private keys\footnote{\url{http://www.loyalty.org/~schoen/rsa/}}.
