    \begin{itemize}
        \item {\bf Deployment types}
        \item {\bf Distro} choice
        \item {\bf Hardware specs}
        \item {\bf Authentication}
        \item Other considerations - {\bf settings}, {\bf gotchas}
    \end{itemize}
\end{frame}

\begin{frame}
\frametitle{Deployment types}
    \begin{itemize}
        \item Native install
        \begin{itemize}
            \item Manual
            \item One-liner script - \texttt{INSTALL.sh}: \url{https://github.com/MISP/MISP/tree/2.4/INSTALL}
        \end{itemize}
        \item MISP VM: \url{https://www.circl.lu/misp-images/latest/}
        \item Docker: \url{https://github.com/MISP/misp-docker}
        \item RPM maintained by \texttt{amuehlem}: \url{https://github.com/misp/misp-rpm}
        \item Cloud provider images: \url{https://github.com/MISP/misp-cloud}
        \item LXC images via \texttt{misp-airgap}: \url{https://github.com/MISP/misp-airgap/}
    \end{itemize}
\end{frame}

\begin{frame}
\frametitle{Docker options}
    \begin{itemize}
        \item There are several MISP Docker installations available.
        \item The official MISP Docker installation is maintained by \texttt{ostefano} and can be found at \url{https://github.com/MISP/misp-docker}.
        \item The official MISP Docker image also includes one for the MISP modules.
    \end{itemize}
\end{frame}

\begin{frame}
    \frametitle{Distro options}
        \begin{itemize}
            \item Ubuntu 22.04 (20.04 will also work)
            \begin{itemize}
                \item Our target platform
                \item Our CI target
                \item Use this unless you are absolutely forced not to
                \item This is the platform we can support you with!
            \end{itemize}
            \item CentOS 7
            \begin{itemize}
                \item Annoying to operate
                \item Less tested, though used by many
                \item CentOS is dead. Consider other options
            \end{itemize}
            \item RHEL 7
            \begin{itemize}
                \item Same annoyance as CentOS in general
                \item We test against CentOS in general, some assembly may be required
            \end{itemize}
        \end{itemize}
\end{frame}

\begin{frame}
\frametitle{Hardware specs}
    \begin{itemize}
        \item No firm recommendations, it's highly usage dependent
        \item It's better to go a bit over what you need than under
        \item {\bf SSDs} are massively beneficial
        \item Let's look at what affects specs and some sample configurations
    \end{itemize}
\end{frame}

\frametitle{Hardware considerations}
    \begin{itemize}
        \item What are the factors that can impact my performance?
        \begin{itemize}
            \item Clustering of the data (how many datapoints / event?) (RAM, disk speed)
            \item Correlation (RAM, disk speed, disk space)
            \begin{itemize}
                \item Consider blocking overtly correlating values from doing so
                \item Feed ingestion strategy is crucial
            \end{itemize}
            \item Over-contextualisation (RAM, disk speed)
            \begin{itemize}
                \item Tag/attach galaxies to the event instead of each attribute when possible
            \end{itemize}
        \end{itemize}
    \end{itemize}
\end{frame}

\begin{frame}
\frametitle{Hardware considerations - continues}
    \begin{itemize}
        \item What are the factors that can impact my performance?
        \begin{itemize}
            \item Number of users that are active at any given time (RAM, CPU, disk speed)
            \item Logging strategy (Disk space)
            \item API users especially with heavy searches (substring searches for example) (RAM, CPU, Disk speed)
        \end{itemize}
    \end{itemize}
\end{frame}

\begin{frame}
\frametitle{Hardware considerations - continues}
    \begin{itemize}
        \item What are the factors that generally do {\bf NOT} impact my performance as much as expected?
        \begin{itemize}
            \item Warninglist usage
            \item Number of raw attributes on the instance
            \item Number of sync connections / recurring syncs (with measure)
            \item Tools feeding off the automation channels (ZMQ, kafka, syslog)
        \end{itemize}
    \end{itemize}
\end{frame}

\begin{frame}
\frametitle{Authentication options}
    \begin{itemize}
        \item Username/password is the default
        \item Some built in modules by 3rd parties (LDAP, Shibboleth, x509, OpenID, Azure Active Directory)
        \item CustomAuth system for more flexibility
        \item Additionally, consider Email OTP
    \end{itemize}
\end{frame}

\begin{frame}
\frametitle{Other considerations - tuning}
    \begin{itemize}
        \item PHP tuning
        \begin{itemize}
            \item Maximum memory usage (per process)
            \item Timeout settings
            \item Consider setting it per role!
            \item Background processes are exempt
        \end{itemize}
        \item MySQL: key buffer size is important
        \item Generally, tune for few heavy requests rather than many light ones
    \end{itemize}
\end{frame}

\begin{frame}
\frametitle{Other considerations - high availability}
    \begin{itemize}
        \item Clustering
        \begin{itemize}
            \item Load balanced apache servers with MISP
            \item Replicating / mirrored database backends
        \end{itemize}
        \item Careful about session pinning
        \item Attachment storage can be abstracted / network attached
        \item An example implementation for AWS \url{https://github.com/0xtf/HAMISPA}
    \end{itemize}
