 \frametitle{MISP features}
 \begin{itemize}
         \item MISP\footnote{\url{https://github.com/MISP/MISP}} is a threat information sharing free \& open source software.
         \item MISP has {\bf a host of functionalities} that assist users in creating, collaborating \& sharing threat information - e.g. flexible sharing groups, {\bf automatic correlation}, free-text import helper, event distribution \& proposals.
         \item Many export formats which support IDSes / IPSes (e.g. Suricata, Bro, Snort), SIEMs (eg CEF), Host scanners (e.g. OpenIOC, STIX, CSV, yara), analysis tools (e.g. Maltego), DNS policies (e.g. RPZ).
         \item A rich set of MISP modules\footnote{\url{https://www.github.com/MISP/misp-modules}} to add expansion, import and export functionalities.
 \end{itemize}

 \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}
\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 950 organizations with more than 2400 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).

\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)

                    \item {\bf Objects} are custom templated Attribute compositions
                    \item {\bf Object references} are the relationships between other building blocks

        \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.
