Speeding up project using Zend_Db

<p>An existing project realized with the Zend Framework should be optimized in terms of performance. The use of Zend_Db slows down the database access because of its automatic table-scanning and overhead. The SQL-queries as well as the table structures are already optimized and should not be changed.

Securing a service using WS-Security

The software used on the server:</p><ul><li>Java 6</li><li>Apache CXF 2.2.3</li><li>SOAP Webservice</li></ul><p>Because of massive abuse in the past the access should be limited to authorized people only. The login credentials are stored in a database and should be checked with every request made on the service.

Secure the Thomson TG585

<p>The Thomson TG585 v7 provided by the Telekom Austria (with a branded firmware) is delivered with system access from every user registered with the modem by wlan or lan. The problem is that the modem knows a default-user (with default-privileges) who can get system access without any password. This user can add other users with passwords, but his own password is still blank so everone in the network is able to have access to the system of the modem.
