\frametitle{Objects - or How We Learned to Stop Worrying and Love the Templates}
|
||||
\begin{itemize}
|
||||
\item Attributes are a simple but powerful tool to describe data
|
||||
\item Lacking the capability to create containers around attributes describing a common concept
|
||||
\item The goal was to develop something semi-standardised, with the option to {\bf dynamically build templates}
|
||||
\item We have considered a list of different solutions such as simple boolean operators, but found that the current implementation was superior.
|
||||
\item The result is a simple template that uses the basic attriubte types as building blocks along with some meta data
|
||||
\item The template does {\bf not have to be known} in order to use the constructed objects
|
||||
\item What we maintain now is a set of common objects, but similarly to our other JSON formats, users can extend it with their own ideas.

\frametitle{MISP Object Templates}
|
||||
\begin{itemize}
|
||||
\item Using a similar JSON format as the taxonomies, galaxies, warninglists.
|
||||
\item You can find the default set of object templates in the git repository\footnote{\url{https://www.github.com/MISP/misp-objects/}}.
|
||||
\item Some of the object templates capture objects from other standards or mimic the output of tools
|
||||
\item We tried to capture the most common use-cases coming from our own use-case as well as those of various partners that got involved
|
||||
\item Improvements or pull requests for new object templates are of course always welcome

\item Android permission - {\bf An object used to further contextualise another object}

\item Bank account

\begin{itemize}
|

\item Primary key: Object relation
|
||||
\item description: A description of the attribute in relation to the object
|
||||
\item disable\_correlation: You can disable correlations for attributes in the resulting object
|
||||
\item ui-priority: Not implemented yet, but the idea is to have a "quick view" of objects only showing certain prio levels
|
||||
\item misp-attribute: The misp attribute type used as as the building block
|
||||
\item values\_list: an optional list of values from which the user {\bf must} choose instead of entering a value manually
|
||||
\item sane\_defaults: an optional list of values from which the user {\bf may} choose instead of entering a value
|
||||
\item multiple: Allow the user to add {\bf more} than one of this attribute

\frametitle{Enforcement of certain keys}
|
||||
\begin{itemize}
|
||||
\item The template also defines which of the added attributes are mandatory
|
||||
\item Requirements are pointed to via their {\bf object relations names}
|
||||
\item We differentiate between two types of rule sets:
|
||||
\begin{itemize}
|
||||
\item Required: Everything in this list has to be set in order for the object to validate
|
||||
\item Required One Of: Any of the attributes in this list will satisfy the requirements
|
||||
\end{itemize}

\end{itemize}

|
||||
|
||||
\begin{frame}
|
||||
\frametitle{What will the the template actually do?}
|
||||
\begin{itemize}
|
||||
\item Templates create a form that can be used to populate an event
|
||||
\item When using templates, MISP will enforce everything according to the template rules
|
||||
\item However, these are only optional, users can avoid using the templates when creating events via the API
|
||||
\item The reason for this is that you do not need to have the template in order to create an object
|
||||
\item The limitation of this system: You {\bf cannot modify} objects that were created with unknown templates

||||
