+Initializing the Security Database
+----------------------------------
+The security database (security4.fdb) has no predefined users. This is intentional.
+You will need to create the user SYSDBA and set up the password for it
+using SQL CREATE USER command syntax in embedded mode as your first step to getting
+access to databases and utilities.
+
+Initialization is performed in embedded mode using the isql utility. For an embedded connection, an authentication
+password is not required and will be ignored if you provide one. An embedded connection will work fine
+with no login credentials and "log you in" using your host credentials if you omit a user name. However, even
+though the user name is not subject to authentication, creating or modifying anything in the existing security
+database requires that the user be SYSDBA; otherwise, isql will throw a privilege error for the CREATE USER
+request.
+
+The SQL user management commands will work with any open database. Because the sample database employee.fdb
+is present in your installation and already aliased in databases.conf, it is convenient to use
+it for the user management task.
+
+1. Stop the Firebird server. Firebird 4 caches connections to the security database aggressively. The presence
+   of server connections may prevent isql from establishing an embedded connection.
+2. In a suitable shell, start an isql interactive session, opening the employee database via its alias:
+    > isql -user sysdba employee
+3. Create the SYSDBA user:
+    WARNING! Do not just copy and paste! Generate your own strong password!
+
+    SQL> create or alter user SYSDBA password 'StrongPassword';
+    SQL> commit;
+    SQL> quit;
+
+	WARNING! Do not just copy and paste! Generate your own strong password!
+4. To complete the initialization, start the Firebird server again. Now you will be able to perform a network
+   login to databases, including the security database, using the password you assigned to SYSDBA.
+
+An effective password, using the default user manager Srp, can be up to 20 characters, although a password
+of up to 255 characters will be valid.
+
+The initialization can also be scripted using the file input option of isql with the content being same as interactive usage.
