# Common Cloud Computing Threat Model (CCCTM) It is legacy. Use the [ACCTP threat model](ODTMACCTP.md) instead. This model is an example of domain-specific threat model. It depicts some common threats to cloud systems. The model is implemented as a OWL ontology. * [OWL file](../OdTMCCCTM.owl) Note: please use [old version of the base model](../old/OdTMBaseThreatModelv02.owl) with this one. There is also the similar model, implemented as a [threat template](https://github.com/nets4geeks/CCCTM_template) in the XML format for the Microsoft Threat Modelling (TM) tool. It can be used to prove different ideas (see below). Also if someone made a decision to create an opensource, ontology-driven alternative to Microsoft TM, the CCCTM ontology could be used to test the software means. Note, that it does not have a countermeasure hierarchy.
