 241 Security Considerations
 242 =======================
 243
 244 * Do you have any external interfaces other than RESTCONF? Yes, OpenFlow devices
 245 * Other security issues?
 246
 247   * `Insecure OpenFlowPlugin <--> OpenFlow device connections <https://wiki.opendaylight.org/view/OpenDaylight_OpenFlow_Plugin:_TLS_Support>`_
 248   * Topology spoofing: non authenticated LLDP packets to detect links between switches which makes it vulnerable to a number of attacks, one of which is topology spoofing  The problem is that all controllers we have tested set chassisSubtype value to the MAC address of the local port of the switch, which makes it easy for an adversary to spoof that switch since controllers use that MAC address as a unique identifier of the switch. By intercepting clear LLDP packets containing MAC addresses, a malicious switch can spoof other switches to falsify the controller’s topology graph.
 249   * DoS: an adversary switch could generate LLDP flood resulting in bringing down the openflow network
 250   * `DoS attack when the switch rejects to receive packets from the controller <https://wiki.opendaylight.org/view/Security_Advisories#.5BModerate.5D_CVE-2017-1000357_Denial_of_Service_attack_when_the_switch_rejects_to_receive_packets_from_the_controller>`_

 258
 259 Migration
 260 ---------
 261
 262 * Is it possible to migrate from the previous release? If so, how?
 263
 264   Yes, OpenFlowJava was merged into OpenFlowPlugin, so if project was relying on **org.opendaylight.openflowjava** dependency, it was moved to **org.opendaylight.openflowplugin.openflowjava**. Feature **odl-openflowjava-protocol** is same as before.
 265
 266 Compatibility
 267 -------------
 268
 269 * Is this release compatible with the previous release? Yes
 270 * Any API changes? Yes, `mastershipChangeServiceManager <https://git.opendaylight.org/gerrit/gitweb?p=openflowplugin.git;a=blob;f=openflowplugin-api/src/main/java/org/opendaylight/openflowplugin/api/openflow/mastership/MastershipChangeServiceManager.java>` and `reconcilliationManager <https://git.opendaylight.org/gerrit/gitweb?p=openflowplugin.git;a=blob;f=applications/reconciliation-framework/src/main/java/org/opendaylight/openflowplugin/applications/reconciliation/ReconciliationManager.java>` blueprint services was added
