+# Security incidents in e-INFRA / MetaCentrum Cloud 
+This document describes details of process when CyberSecurity incidents is detected in the MetaCentrum Cloud.
+
+## Workflow
+
+![metacentrum_cloud_incidents.drawio.png](images/metacentrum_cloud_incidents.drawio.png)
+
+
+The MetaCentrum Security team detects suspicious VM and creates ticket in the RT instance `rt.cesnet.cz`, queue `cloud` and specifies actions to be taken by the MetaCentrum Cloud team including
+  - provide identity of the VM owner  
+  - share snapshot of the VM
+  - instruction how to address the VM further (stop, keep, etc)
+
+MetaCentrum Security handles communication with the user - owner of the Openstack project where the VM originates from. 
+
+Cloud team transfers the VM snapshot into Openstack project `meta-cloud-metac_sec-cerit_sec`. Access to this project is granted via Perun groups `meta-cloud-admins` (Cloud team) and `meta-sec` (Security team). [Available automation](https://gitlab.ics.muni.cz/cloud/g2/openstack-infrastructure-as-code-automation/clouds/g1/brno/security-incidents):
+
+  - `acquire_snapshot_and_create_volume_transfer.sh <THE_ORIGINAL_VM_VOLUME_ID>`
+  - `accept_volume_transfer.sh <VOLUME_TRANSFER_ID>` => results in a new volume with id shared with the Security team. 
+
+MetaCentrum Security runs a new VM with the new volume attached (not mounted). The VM can be accessed by a private key which is complementary to the provided public key passed in. 
+ - `run_vm_with_attached_volume.sh <VOLUME_ID> <SSH_PUB_KEY_LOCATION>`
+
+MetaCentrum Security cleans up the resources
+- `destroy_the_vm.sh`
+
+
+#### The provided automation requires following to be in place
