Can you elaborate on what you mean by 'secure' here...

If you want to restrict access to the database with respect to which 
user can connect to derby database, you could turn on  user authentication.

To set user authentication, the property is

Before this, you would have to set users that can access the database. 

E.g. for default builtin authentication provided by derby, you would 
have to set the following property  to define a user 'sunitha' with 
password 'pwd'

Now to connect to derby, you would have to ensure that the userid, 
password combination is correct and valid , otherwise you will get the 
error 'Connection refused:Invalid authentication'.

$ java org.apache.derby.tools.ij
ij version 10.2
ij> connect 'jdbc:derby:testdb;create=true;user=sunitha;password=pwd';   
ij> connect 'jdbc:derby:testdb;create=true;user=sunitha;password=pwd2';
ERROR 08004: Connection refused : Invalid authentication.
ij> connect 'jdbc:derby:testdb;create=true;user=sunitha2;password=pwd2';
ERROR 08004: Connection refused : Invalid authentication.
