\frametitle{MISP and starting from a practical use-case}
\begin{itemize}
\item During a malware analysis workgroup in 2012, we discovered that we worked on the analysis of the same malware.
\item We wanted to share information in an easy and automated way {\bf to avoid duplication of work}.
\item Christophe Vandeplas (then working at the CERT for the Belgian MoD) showed us his work on a platform that later became MISP.
\item A first version of the MISP Platform was used by the MALWG and {\bf the increasing feedback of users} helped us to build an improved platform.
\item MISP is now {\bf a community-driven development}.
\end{itemize}
\note[item]{Explaining the overall history of MISP especially the aspect of starting on a focused topic "malware reversing" to a more generic open source solution for sharing information.}

\frametitle{about CIRCL}
The Computer Incident Response Center Luxembourg (CIRCL) is a government-driven initiative designed to provide a systematic response facility to computer security threats and incidents. CIRCL is the CERT for the private sector, communes and non-governmental entities in Luxembourg and is operated by LHC g.i.e.

\frametitle{MISP and CIRCL}
\begin{itemize}
\item CIRCL is mandated by the Ministry of Economy and acting as the Luxembourg National CERT for private sector.
\item CIRCL leads the development of the Open Source MISP threat intelligence platform which is used by many military or intelligence communities, private companies, financial sector, National CERTs and LEAs globally.
\item {\bf CIRCL runs multiple large MISP communities performing active daily threat-intelligence sharing}.

\frametitle{What is MISP?}
\begin{itemize}
\item MISP is a {\bf threat information sharing} platform that is free \& open source software
\item A tool that {\bf collects} information from partners, your analysts, your tools, feeds
\item Normalises, {\bf correlates}, {\bf enriches} the data
\item Allows teams and communities to {\bf collaborate}
\item {\bf Feeds} automated protective tools and analyst tools with the output
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Development based on practical user feedback}
\begin{itemize}
\item There are many different types of users of an information sharing platform like MISP:
\begin{itemize}
\item {\bf Malware reversers} willing to share indicators of analysis with respective colleagues.
\item {\bf Security analysts} searching, validating and using indicators in operational security.
\item {\bf Intelligence analysts} gathering information about specific adversary groups.
\item {\bf Law-enforcement} relying on indicators to support or bootstrap their DFIR cases.
\item {\bf Risk analysis teams} willing to know about the new threats, likelyhood and occurences.
\item {\bf Fraud analysts} willing to share financial indicators to detect financial frauds.
\end{itemize}
\end{itemize}

\frametitle{Many objectives from different user-groups}
\begin{itemize}
\item Sharing indicators for a {\bf detection} matter.
\begin{itemize}
\item 'Do I have infected systems in my infrastructure or the ones I operate?'
\end{itemize}
\item Sharing indicators to {\bf block}.
\begin{itemize}
\item 'I use these attributes to block, sinkhole or divert traffic.'
\end{itemize}
\item Sharing indicators to {\bf perform intelligence}.
\begin{itemize}
\item 'Gathering information about campaigns and attacks. Are they related? Who is targeting me? Who are the adversaries?'
\end{itemize}
\item $\rightarrow$ These objectives can be conflicting (e.g. False-positives have different impacts)
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Communities using MISP}
\begin{itemize}
\item Communities are groups of users sharing within a set of common objectives/values.
\item CIRCL operates multiple MISP instances with a significant user base (more than 1200 organizations with more than 4000 users).
\item {\bf Trusted groups} running MISP communities in island mode (air gapped system) or partially connected mode.
\item {\bf Financial sector} (banks, ISACs, payment processing organizations) use MISP as a sharing mechanism.
\item {\bf Military and international organizations} (NATO, military CSIRTs, n/g CERTs,...).
\item {\bf Security vendors} running their own communities (e.g. Fidelis) or interfacing with MISP communities (e.g. OTX).
\item {\bf Topical communities} set up to tackle individual specific issues (COVID-19 MISP)
\end{itemize}
\end{frame}

\frametitle{Sharing Difficulties}
\begin{itemize}
\item Sharing difficulties are not really technical issues but often it's a matter of {\bf social interactions} (e.g. {\bf trust}).
\item Legal restriction\footnote{\url{https://www.misp-project.org/compliance/}}
\begin{itemize}
\item "Our legal framework doesn't allow us to share information."
\item "Risk of information-leak is too high and it's too risky for our organization or partners."
\end{itemize}
\item Practical restriction
\begin{itemize}
\item "We don't have information to share."
\item "We don't have time to process or contribute indicators."
\item "Our model of classification doesn't fit your model."
\item "Tools for sharing information are tied to a specific format, we use a different one."
\end{itemize}
\end{itemize}

\frametitle{Sharing in MISP}
\begin{itemize}
\item Sharing via distribution lists - {\bf Sharing groups}
\item {\bf Delegation} for pseudo-anonymised information sharing
\item {\bf Proposals} and {\bf Extended events} for collaborated information sharing
\item Synchronisation, Feed system, air-gapped sharing
\item User defined {\bf filtered sharing} for all the above mentioned methods
\item Cross-instance information {\bf caching} for quick lookups of large data-sets
\item Support for multi-MISP internal enclaves
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Information quality management}
\begin{itemize}
\item Correlating data
\item Feedback loop from detections via {\bf Sightings}
\item {\bf False positive management} via the warninglist system
\item {\bf Enrichment system} via MISP-modules
\item {\bf workflow} system to review and control information publication
\item {\bf Integrations} with a plethora of tools and formats
\item Flexible {\bf API} and support {\bf libraries} such as PyMISP to ease integration
\item {\bf Timelines} and giving information a temporal context
\item Full chain for {\bf indicator life-cycle management}
\end{itemize}
\end{frame}

\frametitle{Conclusion}
\begin{itemize}
\item {\bf Information sharing practices come from usage} and by example (e.g. learning by imitation from the shared information).
\item MISP is just a tool. What matters is your sharing practices. The tool should be as transparent as possible to support you.
\item Enable users to customize MISP to meet their community's use-cases.
\item MISP project combines open source software, open standards, best practices and communities to make information sharing a reality.
\end{itemize}
