\frametitle{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
|
||||
|
||||
\end{itemize}
|
||||

|

\begin{frame}

\frametitle{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)

||||

D4 header includes an easy way to {\bf extend the protocol} (via type 2) without altering the format. Within a D4 session, the initial D4 packet(s) type 2 defines
|

the custom headers and then the following packets with type 254 is the custom data encapsulated.

\begin{itemize}
|

\item {\bf Confirm} if there is a DDoS attack
|

\item {\bf Recover} time line of attacked targets
|
||||
\item {\bf Confirm} which services (DNS, webserver, $\dots$)
|
||||
\item {\bf Observe} Infrastructure changes
|
||||
\end{itemize}
|
||||
\item {\bf Assess the state of an infrastructure under denial of service attack}
|
||||
\begin{itemize}
|
||||
\item {\bf Detect} failure/addition of intermediate network equipments, firewalls, proxy servers etc
|
||||
\item {\bf Detect} DDoS mitigation devices

\item Create models of DoS/DDoS attacks

D4 - for data collection and processing:
|
||||
\begin{itemize}
|
||||
\item {\bf provide} various points of observation in non contiguous address space,
|
||||
\item {\bf aggregate} and {\bf mix} backscatter traffic collected from D4 sensors,
|
||||
\item {\bf perform} analysis on big amount of data.
|
||||
\end{itemize}
|
||||
|
||||
D4 - from a end-user perspective:
|
||||
\begin{itemize}
|
||||
\item {\bf provide} backscatter analysis results,
|
||||
\item {\bf provide} daily updates,
|
||||
\item {\bf provide} additional relevant (or pivotal) information (DNS, BGP, etc.),
|
||||
\item {\bf provide} an API and search capabilities.

\frametitle{Problem statement}
|

\begin{itemize}
|
||||
\item CIRCL (and other CSIRTs) have their own passive DNS\footnote{\url{https://www.circl.lu/services/passive-dns/}} collection mechanisms
|
||||
\item Current {\bf collection models} are affected with DoH\footnote{DNS over HTTPS} and centralised DNS services
|
||||
\item DNS answers collection is a tedious process
|
||||
\item {\bf Sharing Passive DNS stream} between organisation is challenging due to privacy
|
||||
\end{itemize}
|
||||
\end{frame}
|
||||
|
||||
\begin{frame}
|
||||
\frametitle{Potential Strategy}
|
||||
\begin{itemize}
|
||||
\item Improve {\bf Passive DNS collection diversity} by being closer to the source and limit impact of DoH (e.g. at the OS resolver level)
|
||||
\item Increasing diversity and {\bf mixing models} before sharing/storing Passive DNS records
|
||||
\item Simplify process and tools to install for {\bf Passive DNS collection by relying on D4 sensors} instead of custom mechanisms
|
||||
\item Provide a distributed infrastructure for mixing streams and filtering out the sharing to the validated partners

\begin{itemize}

\item {\bf pivot} on additional data points,

\item {\bf find} owners of IP addresses,

\item {\bf detect} usage of CIDR blocks,
|

\item {\bf detect} vulnerable systems,
|

\item {\bf detect} compromised services,
|

\item {\bf detect} key material reuse,

\item {\bf detect} weak keys.
