# Start and stop ASE

**Start ASE**

**Prerequisite**For ASE to start, the ase\_master.key must be present in the `/opt/pingidentity/ase/config` directory. If you have moved the master key to a secured location for security reasons, copy it to the config directory before executing the start script.

Change working directory to `bin` and run the `start.sh` script.

```
/opt/pingidentity/ase/bin/start.sh
Starting API Security Enforcer 4.1...
please see /opt/pingidentity/ase/logs/controller.log for more details
```

**Stop ASE**

Change working directory to `bin` and run the `stop.sh` script.

```
/opt/pingidentity/ase/bin/stop.sh -u admin –p admin
checking API Security Enforcer status…sending stop request to ASE. please wait…
API Security Enforcer stopped
