+  \includegraphics[scale=0.4]{circl.png}
+  \begin{itemize}
+    \item 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 securitymadein.lu g.i.e.
+  \end{itemize}
+\end{frame}

+\begin{frame}
+  \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}.
+  \end{itemize}
+\end{frame}

+  \frametitle{The aim of this presentation}
+  \begin{itemize}
+     \item To give some insight into what sort of an evolution of our various communities' have gone through as observed over the past 8 years
+     \item Show the importance of {\bf strong contextualisation}...
+     \item ...and how that can be leveraged when trying to make our data {\bf actionable}
+  \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}
+\end{frame}
+
+\begin{frame}
+  \frametitle{The initial scope of MISP}
+  \begin{itemize}
+    \item {\bf Extract information} during the analysis process
+    \item Store and {\bf correlate} these datapoints
+    \item {\bf Share} the data with partners
+    \item Focus on technical indicators: IP, domain, hostname, hashes, filename, pattern in file/memory/traffic
+    \item Generate protective signatures out of the data: snort, suricata, OpenIOC
+  \end{itemize}

+\begin{frame}
+  \frametitle{Why was it so simplistic?}
+  \begin{itemize}
+    \item This was both a reflection of our maturity as a community
+    \begin{itemize}
+      \item Capabilities for {\bf extracting} information
+      \item Capabilities for {\bf utilising} the information
+      \item Lack of {\bf willingness} to share context
+      \item Lack of {\bf co-operation} between teams doing technical analysis/monitoring and threat-intel
+    \end{itemize}
+    \item The more growth we saw in maturity, the more we tried to match it with our data-model, often against pushback
+  \end{itemize}
+\end{frame}
+
+\begin{frame}
+\frametitle{The growing need to contextualise data}
+\begin{itemize}
+       \item There were separate factors that made our data-sets less and less useful for detection/defense in general
+        \begin{itemize}
+                \item {\bf Growth of our communities}
+                \item Distinguish between information of interest and raw data
+                \item {\bf False-positive} management
+                \item TTPs and aggregate information may be prevalent compared to raw data (risk assessment)
+                \item {\bf Increased data volumes} leads to be able to prioritise
+        \end{itemize}
+\end{itemize}
+\end{frame}
+
+\begin{frame}
+\frametitle{Our initial solution}
+\begin{itemize}
+       \item Allow users to {\bf tag any information} created in MISP
+       \item We wanted to be {\bf lax with what we accept} in terms of data, but be {\bf strict on what we fed to our tools}, with strong filter options
+       \item We had some ideas on how to potentially move forward...
+\end{itemize}
+\end{frame}
+
+\begin{frame}
+\frametitle{Our initial failures}
+\begin{itemize}
+       \item Try to capture different aspects of contextualisation into {\bf normalised values} (threat level, source reliability, etc)
+        \begin{itemize}
+                \item Didn't scale with needs other than our own
+                \item Incorporating new types of contextualisation would mean {\bf the modification of the software}
+                \item Getting communities with {\bf established naming conventions} to use anything but their go-to vocabularies was a pipe-dream
+                \item Heated arguments over numeric conversions
+        \end{itemize}
+\end{itemize}
+\end{frame}
+
+\begin{frame}
+  \frametitle{Human creativity}
+  \begin{itemize}
+    \item We tried an alternate approach instead: Free tagging
+    \begin{itemize}
+      \item Result was spectacularly painful, at least 7 different ways to spell tlp:amber
+      \item No canonisation for common terms lead to tagging ultimately becoming a highly flawed tool for filtering within a sharing community
+    \end{itemize}
+  \end{itemize}
+  \begin{center}
+    \includegraphics[scale=0.45]{creativity.png}
+  \end{center}
+\end{frame}
+
+\begin{frame}
+\frametitle{How we ended up tackling the issue more successfuly}
+\begin{itemize}
+       \item We ended up with a mixed approach, currently implemented by the MISP-taxonomy system
+        \begin{itemize}
+                \item Taxonomies are {\bf vocabularies} of known tags
+                \item Tags would be in a {\bf triple tag format}
+                    \begin{itemize}
+                        \item[] \texttt{namespace:predicate=''value''}
+                    \end{itemize}
+                \item Create your own taxonomies, recipients should be able to use data you tag with them without knowing it at the first place
+                \item Avoid any coding, stick to {\bf JSON}
+        \end{itemize}
+        \item Massive success, approaching 100 taxonomies
+        \item Organisations can solve their own issues without having to rely on us
+\end{itemize}
+\includegraphics[scale=0.4]{taxonomy-workflow.png}
+\end{frame}
+
+\begin{frame}
+\frametitle{We were still missing something...}
+    \begin{itemize}
+       \item Taxonomy tags often {\bf non self-explanatory}
+       \item Example: universal understanding of tlp:green vs APT 28
+       \item For the latter, a single string was ill-suited
+       \item So we needed something new in addition to taxonomies - \textbf{Galaxies}
+        \begin{itemize}
+            \item Community driven \textbf{knowledge-base libraries used as tags}
+            \item Including descriptions, links, synonyms, meta information, etc. 
+            \item Goal was to keep it \textbf{simple and make it reusable}
+            \item Internally it works the exact same way as taxonomies (stick to \textbf{JSON})
+        \end{itemize}
+    \end{itemize}
+    \begin{center}

+\begin{frame}
+\frametitle{Broadening the scope of what sort of context we are interested in}
+\begin{itemize}
+       \item {\bf Who} can receive our data? {\bf What} can they do with it?
+       \item {\bf Data accuracy, source reliability}
+       \item {\bf Why} is this data relevant to us?
+       \item {\bf Who} do we think is behind it, {\bf what tools} were used?
+       \item What sort of {\bf motivations} are we dealing with? Who are the {\bf targets}?
+       \item How can we {\bf block/detect/remediate} the attack?
+       \item What sort of {\bf impact} are we dealing with?
+\end{itemize}
+\end{frame}
+
+\begin{frame}
+\frametitle{Parallel to the contextualisation efforts: False positive handling}
+\begin{itemize}
+        \item Low quality / false positive prone information being shared
+        \item Lead to {\bf alert-fatigue}
+        \item Exclude organisation xy out of the community?
+        \item False positives are often obvious - {\bf can be encoded}
+        \item {\bf Warninglist system}\footnote{\url{https://github.com/MISP/misp-warninglists}} aims to do that
+        \item Lists of well-known indicators which are often false-positives like RFC1918 networks, ...
+\end{itemize}

+    \includegraphics[scale=0.22]{warning-list.png}
+    \includegraphics[scale=0.45]{warning-list-event.png}
+\end{center}
+\end{frame}
+
+\begin{frame}
+  \frametitle{More complex data-structures for a modern age}
+  \begin{itemize}
+    \item Atomic attributes were a great starting point, but lacking in many aspects
+    \item {\bf MISP objects}\footnote{\url{https://github.com/MISP/misp-objects}} system
+    \begin{itemize}
+      \item Simple {\bf templating} approach
+      \item Use templating to build more complex structures
+      \item Decouple it from the core, allow users to {\bf define their own} structures
+      \item MISP should understand the data without knowing the templates
+      \item Massive caveat: {\bf Building blocks have to be MISP attribute types}
+      \item Allow {\bf relationships} to be built between objects
+    \end{itemize}
+  \end{itemize}

+\begin{frame}
+  \frametitle{Continuous feedback loop}
+  \begin{itemize}
+    \item Data ingested by MISP was in a sense frozen in time
+    \item We had a creation data, but lacked a way to use the output of our detection
+    \item Lead to the introduction of the {\bf Sighting system}
+    \item The community could sight indicators and convey the time of sighting
+    \item Potentially powerful tool for IoC lifecycle management, clumsy query implementation default

+  \frametitle{Making use of all this context}
+  \begin{itemize}
+    \item Most obvious goal: Improve the way we query data
+    \begin{itemize}
+      \item Unified all export APIs
+      \item Incorporate all contextualisation options into {\bf API filters}
+      \item Allow for an {\bf on-demand} way of {\bf excluding potential false positives}
+      \item Allow users to easily {\bf build their own} export modules feed their various tools

+  \begin{itemize}
+    \item Make decisions on whom to share data with based on context
+    \begin{itemize}
+      \item MISP by default decides based on the information creator's decision who data gets shared with
+      \item Community hosts should be able to {\bf act as a safety net} for sharing
+      \begin{itemize}
+        \item {\bf Push filters} - what can I push?
+        \item {\bf Pull filters} - what am I interested in?

+  \begin{itemize}
+    \item Standardising on high-level {\bf TTPs} was a solution to a long list of issues

+    \item A much better take on kill-chain phases in general

+  \begin{itemize}
+    \item We were still missing a way to use all of these systems in combination to decay indicators
+    \item Move the decision making \textbf{from complex filter options to} complex \textbf{decay models}
+    \item Decay models would take into account various \textbf{taxonomies}, \textbf{sightings}, the \textbf{type} of each indicator \textbf{Sightings} and \textbf{Creation date}
+    \item The first iteration of what we have in MISP now took:
+    \begin{itemize}
+       \item 2 years of research
