Importing and Exporting models¶
You can import models by selecting the System / Import Model menu, selecting the model type to import, and the model file itself.
You will usually want to stick with the Model package (.cairis) option to import .cairis files. .cairis files are zip archives with a model file, any supplemental locations and architectural pattern models, and all the image files associated with the model.
You can, alternatively, select the Model file (.xml) option, which imports a standard CAIRIS XML model file (as defined by the DTD in https://cairis.org/dtd/cairis_model.dtd). If you select this option, you can choose to overwrite an existing model (the default option) or you can incrementally import the contents of a model file into a pre-existing model.
You can also import other types of model into your current working project.
|Model type||DTD (in https://cairis.org/dtd)||Model elements|
|Project data||cairis.dtd||Project background, goal, scope, rich picture, naming conventions, contributors, revisions|
|Requirements||goals.dtd||domain properties, goals, obstacles, requirements, use cases, and countermeasures|
|Risk analysis||riskanalysis.dtd||roles, assets, vulnerabilities, attackers, threats, risks, responses, asset associations|
|Usability||usability.dtd||personas, external documents, document references, concept references, persona characteristics, task characteristics, tasks|
|Misusability||misusability.dtd||concept references, task characteristics|
|Associations||associations.dtd||manual associations, goal associations, dependencies|
|Threat and Vulnerability Types||tvtypes.dtd||vulnerability types, threat types|
|Domain Values||domainvalues.dtd||threat values, risk values, countermeasure values, security values, likelihood values, motivation values, capability values|
|Threat and Vulnerability Directory||directory.dtd||vulnerability directory entries, threat directory entries|
|Security Pattern||securitypattern.dtd||security patterns|
|Architectural Pattern||architectural_pattern.dtd||architectural patterns|
|Attack Pattern||attack_pattern.dtd||attack patterns|
|Synopsis||synopsis.dtd||characteristic synopses, reference synopses, step synopses, reference contributions, usecase contributions|
|Processes||processes.dtd||CSP process elements (used by desktop application only)|
|Dataflows||dataflow.dtd||dataflows and trust boundaries|
|Attack Tree (Dot)||N/A||Graphviz (Dot) representation of an attack tree|
|diagrams.net (Data Flow Diagram)||N/A||diagrams.net drawn DFD|
|diagrams.net (Asset Model)||N/A||diagrams.net drawn asset model|
|User goals (Workbook)||N/A||CAIRIS generated Excel workbook with user goals and contributions|
To export a model, select the System / Export Model option. Exporting the current model renders the current CAIRIS database you are working with as a CAIRIS XML model (conforming to cairis_model.dtd). You can also export a selected architectural pattern, the security patterns currently loaded into CAIRIS, or a GRL model for a selected environment and task; this GRL can be imported into jUCMNav.
