# Running the Network Server without a security policy

You may override the Network Server's impulse to install a security manager if, for some reason, you need to run your application outside Java's security protections.

CAUTION:
You incur a severe security risk by opening up the server to all clients without limiting access via user authentication and a security policy.

Use the -noSecurityManager option to force the Network Server to come up without a security manager. E.g.:

    java org.apache.derby.drda.NetworkServerControl start -h localhost -noSecurityManager
