Intrusion Detection and Prevention (IDP)
IDP db file format or convention has changed in Junos OS Release 15.1X49 and later releases. So, if the IDP configuration contains some predefined attacks or attack groups related configurations, then the system will go to amnesiac mode after upgrade. This is due to the failure in IDP configuration commit. PR1455125
User Access and Authentication
On vSRX 3.0 on Azure, with Microsoft Azure Hardware Security Module (HSM) enabled, keypair generation fails if you reuse the certificate ID for creating a new keypair—even if the previous keypair was deleted. PR1490558
When using Juniper vSRX deployment script deploy-azure-vsrx.sh to create new vSRX instance, if the same user was defined in both parameter.json file and YAML file (using write_files module), both passwords will be configured in different configuration groups in the running configuration of vSRX. The password defined in the YAML file will be considered. PR1491074
